Tasmanian devil - Wikipedia Tasmanian devil For other uses, see Tasmanian Devil ( disambiguation ). Tasmanian devil Conservation status Endangered ( IUCN 3.1 ) Scientific classification Kingdom : Animalia Phylum : Chordata Class : Mammalia Infraclass : Marsupialia Order : Dasyuromorphia Family : Dasyuridae Genus : Sarcophilus Species : S. harrisii Binomial name Sarcophilus harrisii ( Boitard, 1841 ) Distribution of the Tasmanian devil ( grey ) The Tasmanian devil ( Sarcophilus harrisii ) is a carnivorous marsupial of the family Dasyuridae. It was once native to mainland Australia and now found in the wild only on the island state of Tasmania, including tiny east - coast Maria Island where there is a conservation project with disease - free animals. The size of a small dog, the Tasmanian devil became the largest carnivorous marsupial in the world following the extinction of the thylacine in 1936. It is related to quolls and distantly related to the thylacine. It is characterised by its stocky and muscular build, black fur, pungent odour, extremely loud and disturbing screech, keen sense of smell, and ferocity when feeding. The Tasmanian devil 's large head and neck allow it to generate among the strongest bites per unit body mass of any extant mammal land predator, and it hunts prey and scavenges carrion as well as eating household products if humans are living nearby. Although it usually is solitary, it sometimes eats with other devils and defecates in a communal location. Unlike most other dasyurids, the devil thermoregulates effectively and is active during the middle of the day without overheating. Despite its rotund appearance, the devil is capable of surprising speed and endurance, and can climb trees and swim across rivers. It is believed that ancient marsupials migrated from what is now South America to Australia tens of millions of years ago during the time of Gondwana, and that they evolved as Australia became more arid. Fossils of species similar to modern devils have been found, but it is not known whether they were ancestors of the contemporary species, or whether the current devils co-existed with these species. The date that the Tasmanian devil became locally extinct from the Australian mainland is unclear ; most evidence suggests they had contracted to three relict populations around 3000 years ago. A tooth found in Augusta, Western Australia has been dated to 430 years ago, but archaeologist Oliver Brown disputes this and considers the devil 's mainland extinction to have occurred around 3000 years ago. This disappearance is usually blamed on dingoes, which are absent from Tasmania. Because they were seen as a threat to livestock and animals that humans hunted for fur in Tasmania, devils were hunted and became endangered. In 1941, the devils, which were originally seen as implacably vicious, became officially protected. Since then, scientists have contended that earlier concerns that the devils were the most significant threat to livestock were overestimated and misplaced. Devils are not monogamous, and their reproductive process is very robust and competitive. Males fight one another for the females, and then guard their partners to prevent female infidelity. Females can ovulate three times in as many weeks during the mating season, and 80 % of two - year - old females are seen to be pregnant during the annual mating season. Females average four breeding seasons in their life and give birth to 20 -- 30 live young after three weeks ' gestation. The newborn are pink, lack fur, have indistinct facial features and weigh around 0.20 g ( 0.0071 oz ) at birth. As there are only four nipples in the pouch, competition is fierce and few newborns survive. The young grow rapidly and are ejected from the pouch after around 100 days, weighing roughly 200 g ( 7.1 oz ). The young become independent after around nine months, so the female spends most of her year in activities related to birth and rearing. Since the late 1990s, the devil facial tumour disease ( DFTD ) has drastically reduced the devil population and now threatens the survival of the species, which in 2008 was declared to be endangered. Programs are currently being undertaken by the Government of Tasmania to reduce the impact of the disease, including an initiative to build up a group of healthy devils in captivity, isolated from the disease. While the thylacine was extant it preyed on the devil, which targeted young and unattended thylacine cubs in their dens. Localised populations of devils have also been severely reduced by collisions with motor vehicles, particularly when they are eating roadkill. The devil is an iconic symbol of Tasmania and many organisations, groups and products associated with the state use the animal in their logos. It is seen as an important attractor of tourists to Tasmania and has come to worldwide attention through the Looney Tunes character of the same name. Starting in 2013, Tasmanian devils are again being sent to zoos around the world as part of the Australian government 's Save the Tasmanian Devil Program.

He had earlier made a presentation on the topic at the Zoological Society of London. However, that particular binomial name had been given to the common wombat ( later reclassified as Vombatus ursinus ) by George Shaw in 1800, and was hence unavailable. In 1838, a specimen was named Dasyurus laniarius by Richard Owen, but by 1877 he had relegated it to Sarcophilus. The modern Tasmanian devil was named Sarcophilus harrisii ( `` Harris 's meat - lover '' ) by French naturalist Pierre Boitard in 1841. A later revision of the devil 's taxonomy, published in 1987, attempted to change the species name to Sarcophilus laniarius based on mainland fossil records of only a few animals. However, this was not accepted by the taxonomic community at large ; the name S. harrisii has been retained and S. laniarius relegated to a fossil species. `` Beelzebub 's pup '' was an early vernacular name given to it by the explorers of Tasmania, in reference to a religious figure who is a prince of hell and an assistant of Satan ; the explorers first encountered the animal by hearing its far - reaching vocalisations at night. Related names that were used in the 19th century were Sarcophilus satanicus ( `` Satanic meatlover '' ) and Diabolus ursinus ( `` bear devil '' ), all due to early misconceptions of the devil as implacably vicious. The Tasmanian devil ( Sarcophilus harrisii ) belongs to the family Dasyuridae. The genus Sarcophilus contains two other species, known only from Pleistocene fossils : S. laniarius and S. moomaensis. The relationships between the three species are not clear. Phylogenetic analysis shows that the Tasmanian devil is most closely related to quolls. The roots of Australian marsupials are thought to trace back tens of millions of years to when much of the current Southern Hemisphere was part of the supercontinent of Gondwana ; marsupials are believed to have originated in what is now South America and migrated across Antarctica, which had a temperate climate at the time. As soil degradation took hold, it is believed that the marsupials adapted to the more basic flora of Australia. According to Pemberton, the possible ancestors of the devil may have needed to climb trees to acquire food, leading to a growth in size and the hopping gait of many marsupials. He speculated that these adaptations may have caused the contemporary devil 's peculiar gait. The specific lineage of the Tasmanian devil is theorised to have emerged during the Miocene, molecular evidence suggesting a split from the ancestors of quolls between 10 and 15 million years ago, when severe climate change came to bear in Australia, transforming the climate from warm and moist to an arid, dry ice age, resulting in mass extinctions. As most of their prey died of the cold, only a few carnivores survived, including the ancestors of the quoll and thylacine. It is speculated that the devil lineage may have arisen at this time to fill a niche in the ecosystem, as a scavenger that disposed of carrion left behind by the selective - eating thylacine. The extinct Glaucodon ballaratensis of the Pliocene age has been dubbed an intermediate species between the quoll and devil. A jawbone found in the mainland Jenolan Caves Fossil deposits in limestone caves at Naracoorte, South Australia, dating to the Miocene include specimens of S. laniarius, which were around 15 % larger and 50 % heavier than modern devils. Older specimens believed to be 50 -- 70,000 years old were found in Darling Downs in Queensland and in Western Australia. It is not clear whether the modern devil evolved from S. laniarius, or whether they coexisted at the time. Richard Owen argued for the latter hypothesis in the 19th century, based on fossils found in 1877 in New South Wales. Large bones attributed to S. moornaensis have been found in New South Wales, and it has been conjectured that these two extinct larger species may have hunted and scavenged. It is known that there were several genera of thylacine millions of years ago, and that they ranged in size, the smaller being more reliant on foraging. As the devil and thylacine are similar, the extinction of the co-existing thylacine genera has been cited as evidence for an analogous history for the devils. It has been speculated that the smaller size of S. laniarius and S. moornaensis allowed them to adapt to the changing conditions more effectively and survive longer than the corresponding thylacines. As the extinction of these two species came at a similar time to human habitation of Australia, hunting by humans and land clearance have been mooted as possible causes. Critics of this theory point out that as indigenous Australians only developed boomerangs and spears for hunting around 10,000 years ago, a critical fall in numbers due to systematic hunting is unlikely. They also point out that caves inhabited by Aborigines have a low proportion of bones and rock paintings of devils, and suggest that this is an indication that it was not a large part of indigenous lifestyle. A scientific report in 1910 claimed that Aborigines preferred the meat of herbivores rather than carnivores. The other main theory for the extinction was that it was due to the climate change brought on by the most recent ice age. While dingoes are seen as the main reason for the disappearance of devils from the mainland, another theory is that the increasing aridity of the mainland caused it, while the population in Tasmania has been largely unaffected as the climate remains cool and moist. According to this theory, the dingo was only a secondary cause. As the devil is the thylacine 's closest relative, there has been speculation that the thylacine could be revived by combining DNA from museum samples of thylacines with ova of the devil. Genetics Karyotype of male Tasmanian devil. The Tasmanian devil 's genome was sequenced in 2010 by the Wellcome Trust Sanger Institute. Like all dasyurids, the devil has 14 chromosomes. Devils have a low genetic diversity compared to other Australian marsupials and placental carnivores ; this is consistent with a founder effect as allelic size ranges were low and nearly continuous throughout all subpopulations measured. Allelic diversity was measured at 2.7 -- 3.3 in the subpopulations sampled, and heterozygosity was in the range 0.386 -- 0.467. According to a study by Menna Jones, `` gene flow appears extensive up to 50 km ( 31 mi ) '', meaning a high assignment rate to source or close neighbour populations `` in agreement with movement data. At larger scales ( 150 -- 250 km or 90 -- 200 mi ), gene flow is reduced but there is no evidence for isolation by distance ''. Island effects may also have contributed to their low genetic diversity. Periods of low population density may also have created moderate population bottlenecks, reducing genetic diversity. Low genetic diversity is thought to have been a feature in the Tasmanian devil population since the mid-Holocene. Outbreaks of devil facial tumour disease ( DFTD ) cause an increase in inbreeding. A sub-population of devils in the north - west of the state is genetically distinct from other devils, but there is some exchange between the two groups. One strand conformation polymorphism analysis ( OSCP ) on the major histocompatibility complex ( MHC ) class I domain taken from various locations across Tasmania showed 25 different types, and showed a different pattern of MHC types in north - western Tasmania to eastern Tasmania. Those devils in the east of the state have less MHC diversity ; 30 % are of the same type as the tumour ( type 1 ), and 24 % are of type A. Seven of every ten devils in the east are of type A, D, G or 1, which are linked to DFTD ; whereas only 55 % of the western devils fall into these MHC categories. Of the 25 MHC types, 40 % are exclusive to the western devils. Although the north - west population is less genetically diverse overall, it has higher MHC gene diversity, which allows them to mount an immune response to DFTD. According to this research, mixing the devils may increase the chance of disease. Of the fifteen different regions in Tasmania surveyed in this research, six were in the eastern half of the island. In the eastern half, Epping Forest had only two different types, 75 % being type O. In the Buckland - Nugent area, only three types were present, and there were an average of 5.33 different types per location. In contrast, in the west, Cape Sorell yielded three types, and Togari North - Christmas Hills yielded six, but the other seven sites all had at least eight MHC types, and West Pencil Pine had 15 types. There was an average of 10.11 MHC types per site in the west. Recent research has suggested that the wild population of devils are rapidly evolving a resistance to DFTD. Description Two devils, one without any white markings. Around 16 % of wild devils have no markings. The Tasmanian devil 's whiskers help it to locate prey in the dark. Dentition, as illustrated in Knight 's Sketches in Natural History The Tasmanian devil is the largest surviving carnivorous marsupial. It has a squat, thick build, with a large head and a tail which is about half its body length. Unusually for a marsupial, its forelegs are slightly longer than its hind legs, and devils can run up to 13 km / h ( 8.1 mph ) for short distances. The fur is usually black, often with irregular white patches on the chest and rump ( although approximately 16 % of wild devils do not have white patches ). These markings suggest that the devil is most active at dawn and dusk, and they are thought to draw biting attacks toward less important areas of the body, as fighting between devils often leads to a concentration of scars in that region. Males are usually larger than females, having an average head and body length of 652 mm ( 25.7 in ), a 258 mm ( 10.2 in ) tail and an average weight of 8 kg ( 18 lb ). Females have an average head and body length of 570 mm ( 22 in ), a 244 mm ( 9.6 in ) tail and an average weight of 6 kg ( 13 lb ), although devils in western Tasmania tend to be smaller. Devils have five long toes on their forefeet, four pointing to the front and one coming out from the side, which gives the devil the ability to hold food. The hind feet have four toes, and the devils have non-retractable claws. The stocky devils have a relatively low centre of mass. Devils are fully grown at two years of age, and few devils live longer than five years in the wild. Possibly the longest - lived Tasmanian devil recorded was Coolah, a male devil which lived in captivity for more than seven years. Born in January 1997 at the Cincinnati Zoo, Coolah died in May 2004 at the Fort Wayne Children 's Zoo. The devil stores body fat in its tail, and healthy devils have fat tails. The tail is largely non-prehensile and is important to its physiology, social behaviour and locomotion. It acts as a counterbalance to aid stability when the devil is moving quickly. An ano - genital scent gland at the base of its tail is used to mark the ground behind the animal with its strong, pungent scent. The male has external testes in a pouch - like structure formed by lateral ventrocrural folds of the abdomen, which partially hides and protects them. The testes are subovoid in shape and the mean dimensions of 30 testes of adult males was 3.17 cm × 2.57 cm ( 1.25 in × 1.01 in ). The female 's pouch opens backwards, and is present throughout its life, unlike some other dasyurids. Tasmanian devil skull in The Museum of Zoology, St. Petersburg, Russia Tasmanian devil skeleton on display at the Museum of Osteology, Oklahoma City, Oklahoma. The Tasmanian devil has an exceptionally strong bite for its size, generating a force of over 553 N ( 124 lbf ). The jaw can open to 75 -- 80 degrees, allowing the devil to generate the large amount of power to tear meat and crush bones -- sufficient force to allow it to bite through thick metal wire. The power of the jaws is in part due to its comparatively large head. The teeth and jaws of Tasmanian devils resemble those of hyenas, an example of convergent evolution. Dasyurid teeth resemble those of primitive marsupials. Like all dasyurids, the devil has prominent canines and cheek teeth. It has three pairs of lower incisors and four pairs of upper incisors. These are located at the top of the front of the devil 's mouth. Like dogs, it has 42 teeth, however, unlike dogs, its teeth are not replaced after birth but grow continuously throughout life at a slow rate. It has a `` highly carnivorous dentition and trophic adaptations for bone consumption ''. The devil has long claws that allow it to dig burrows and seek subterranean food easily and grip prey or mates strongly. The teeth and claw strength allow the devil to attack wombats up to 30 kg ( 66 lb ) in weight. The large neck and forebody that give the devil its strength also cause this strength to be biased towards the front half of the body ; the lopsided, awkward, shuffling gait of the devil is attributed to this. The devil has long whiskers on its face and in clumps on the top of the head. These help the devil locate prey when foraging in the dark, and aid in detecting when other devils are close during feeding. The whiskers can extend from the tip of the chin to the rear of the jaw and can cover the span of its shoulder. Hearing is its dominant sense, and it also has an excellent sense of smell, which has a range of 1 kilometre ( 0.6 mi ). The devil, unlike other marsupials, has a `` well - defined, saddle - shaped ectotympanic ''. Since devils hunt at night, their vision seems to be strongest in black and white. In these conditions they can detect moving objects readily, but have difficulty seeing stationary objects. Distribution and habitat Devils are found in all habitats on the island of Tasmania, including the outskirts of urban areas, and are distributed throughout the Tasmanian mainland and on Robbins Island ( which is connected to mainland Tasmania at low tide ). The north - western population is located west of the Forth River and as far south as Macquarie Heads. Previously, they were present on Bruny Island from the 19th century, but there have been no records of them after 1900, and they were introduced to Badger Island in the mid-1990s but are thought to have died out by 2005. A study has modelled the reintroduction of DFTD - free Tasmanian devils to the mainland in areas where dingoes are sparse. It is proposed that devils would have fewer impacts on both livestock and native fauna than dingoes, and that the mainland population could act as an additional insurance population. In September 2015, 20 immunised captive - bred devils were released into Narawntapu National Park, Tasmania. Two later died from being hit by cars. The `` core habitat '' of the devils is considered to be within the `` low to moderate annual rainfall zone of eastern and north - western Tasmania ''. Tasmanian devils particularly like dry sclerophyll forests and coastal woodlands. Although they are not found at the highest altitudes of Tasmania, and their population density is low in the button grass plains in the south - west of the state, their population is high in dry or mixed sclerophyll forests and coastal heaths. Devils prefer open forest to tall forest, and dry rather than wet forests. They are also found near roads where roadkill is prevalent, although the devils themselves are often killed by vehicles while retrieving the carrion. According to the Threatened Species Scientific Committee, their versatility means that habitat modification from destruction is not seen as a major threat to the species. The devil is directly linked to the Dasyurotaenia robusta, a tapeworm which is classified as Rare under the Tasmanian Threatened Species Protection Act 1995. This tapeworm is found only in devils. Ecology. and behaviour Although Tasmanian devils are nocturnal, they like to rest in the sun. Scarring from fighting is visible next to this devil 's left eye The Tasmanian devil is a nocturnal and crepuscular hunter, spending the days in dense bush or in a hole. It has been speculated that nocturnalism may have been adopted to avoid predation by eagles and humans. Young devils are predominantly crepuscular. There is no evidence of torpor. Young devils can climb trees, but this becomes more difficult as they grow larger. Devils can scale trees of trunk diameter larger than 40 cm ( 16 in ), which tend to have no small side branches to hand onto, up to a height of around 2.5 -- 3 m ( 8.2 -- 9.8 ft ). Devils that are yet to reach maturity can climb shrubs to a height of 4 metres ( 13.1 ft ), and can climb a tree to 7 m ( 23 ft ) if it is not vertical. Adult devils may eat young devils if they are very hungry, so this climbing behaviour may be an adaptation to allow young devils to escape. Devils can also swim and have been observed crossing rivers that are 50 metres ( 160 ft ) in width, including icy cold waterways, apparently enthusiastically. Tasmanian devils do not form packs, but rather spend most of their time alone once weaned. Classically considered as solitary animals, their social interactions were poorly understood. However, a field study published in 2009 shed some light on this. Tasmanian devils in Narawntapu National Park were fitted with proximity sensing radio collars which recorded their interactions with other devils over several months from February to June 2006. This revealed that all devils were part of a single huge contact network, characterised by male - female interactions during mating season, while female -- female interactions were the most common at other times, although frequency and patterns of contact did not vary markedly between seasons. Previously thought to fight over food, males only rarely interacted with other males. Hence, all devils in a region are part of a single social network. They are considered to be non-territorial in general, but females are territorial around their dens. This allows a higher total mass of devils to occupy a given area than territorial animals, without conflict. Tasmanian devils instead occupy a home range. In a period of between two and four weeks, devils ' home ranges are estimated to vary between 4 and 27 km ( 990 and 6,670 acres ), with an average of 13 km ( 3,200 acres ). The location and geometry of these areas depend on the distribution of food, particularly wallabies and pademelons nearby. Devils use three or four dens regularly. Dens formerly owned by wombats are especially prized as maternity dens because of their security. Dense vegetation near creeks, thick grass tussocks, and caves are also used as dens. Adult devils use the same dens for life. It is believed that, as a secure den is highly prized, some may have been used for several centuries by generations of animals. Studies have suggested that food security is less important than den security, as habitat destruction that impacts the latter has had more effect on mortality rates. Young pups remain in one den with their mother, and other devils are mobile, changing dens every 1 -- 3 days and travelling a mean distance of 8.6 kilometres ( 5.3 mi ) every night. However, there are also reports that an upper bound can be 50 kilometres ( 31 mi ) per night. They choose to travel through lowlands, saddles and along the banks of creeks, particularly preferring carved - out tracks and livestock paths and eschewing steep slopes and rocky terrain. The amount of movement is believed to be similar throughout the year, except for mothers who have given birth recently. The similarity in travel distances for males and females is unusual for sexually dimorphic, solitary carnivores. As a male needs more food, he will spend more time eating than travelling. Devils typically make circuits of their home range during their hunts. In areas near human habitation, they are known to steal clothes, blankets and pillows and take them for use in dens in wooden buildings. While the dasyurids have similar diet and anatomy, differing body sizes affect thermoregulation and thus behaviour. In ambient temperatures between 5 and 30 ° C ( 41 and 86 ° F ), the devil was able to maintain a body temperature between 37.4 and 38 ° C ( 99.3 and 100.4 ° F ). When the temperature was raised to 40 ° C ( 104 ° F ), and the humidity to 50 %, the devil 's body temperature spiked upwards by 2 ° C ( 3.6 ° F ) within 60 minutes, but then steadily decreased back to the starting temperature after a further two hours, and remained there for two more hours. During this time, the devil drank water and showed no visible signs of discomfort, leading scientists to believe that sweating and evaporative cooling is its primary means of heat dissipation. A later study found that devils pant but do not sweat to release heat. In contrast, many other marsupials were unable to keep their body temperatures down. As the smaller animals have to live in hotter and more arid conditions to which they are less well - adapted, they take up a nocturnal lifestyle and drop their body temperatures during the day, whereas the devil is active in the day and its body temperature varies by 1.8 ° C ( 3.2 ° F ) from its minimum at night to the maximum in the middle of the day. The standard metabolic rate of a Tasmanian devil is 141 kJ / kg ( 15.3 kcal / lb ) per day, many times lower than smaller marsupials. A 5 - kilogram ( 11 lb ) devil uses 712 kilojoules ( 170 kcal ) per day. The field metabolic rate is 407 kJ / kg ( 44.1 kcal / lb ). Along with quolls, Tasmanian devils have a metabolic rate comparable to non-carnivorous marsupials of a similar size. This differs from placental carnivores, which have comparatively high basal metabolic rates. A study of devils showed a loss of weight from 7.9 to 7.1 kilograms ( 17 to 16 lb ) from summer to winter, but in the same time, daily energy consumption increased from 2,591 to 2,890 kilojoules ( 619 to 691 kcal ). This is equivalent to an increase in food consumption from 518 to 578 grams ( 18.3 to 20.4 oz ). The diet is protein - based with 70 % water content. For every 1 gram ( 0.035 oz ) of insects consumed, 3.5 kilojoules ( 0.84 kcal ) of energy are produced, while a corresponding amount of wallaby meat generated 5.0 kilojoules ( 1.2 kcal ). In terms of its body mass, the devil eats only a quarter of the eastern quoll 's intake, allowing it to survive longer during food shortages. The devil is a keystone species in the ecosystem of Tasmania. Feeding A devil eating roadkill Tasmanian devils can take prey up to the size of a small kangaroo, but in practice they are opportunistic and eat carrion more often than they hunt live prey. Although the devil favours wombats because of the ease of predation and high fat content, it will eat all small native mammals such as bettong and potoroos, domestic mammals ( including sheep ), birds, fish, fruit, vegetable matter, insects, tadpoles, frogs and reptiles. Their diet is widely varied and depends on the food available. Before the extinction of the thylacine, the Tasmanian devil ate thylacine cubs left alone in dens when their parents were away. This may have helped to hasten the extinction of the thylacine, which also ate devils. They are known to hunt water rats by the sea and forage on dead fish that have been washed ashore. Near human habitation, they can also steal shoes and chew on them, and eat the legs of otherwise robust sheep when they have slipped in wooden shearing sheds, leaving their legs dangling below. Other unusual matter observed in devil scats includes collars and tags of devoured animals, intact echidna spines, pencil, plastic and jeans. Although devils can bite through metal traps, they tend to reserve their strong jaws for escaping captivity rather than breaking into food storage. Due to their relative lack of speed, they can not run down a wallaby or a rabbit, but they can attack animals that have become slow due to illness. They survey flocks of sheep by sniffing them from 10 -- 15 m ( 33 -- 49 ft ) away and attack if the prey is ill. The sheep stamp their feet in a show of strength. Despite their lack of extreme speed, there have been reports that devils can run at 25 km / h ( 16 mph ) for 1.5 km ( 0.93 mi ), and it has been conjectured that, before European immigration and the introduction of livestock, vehicles and roadkill, they would have had to chase other native animals at a reasonable pace to find food. Pemberton has reported that they can average 10 km / h ( 6.2 mph ) for `` extended periods '' on several nights per week, and that they run for long distances before sitting still for up to half an hour, something that has been interpreted as evidence of ambush predation. Devils can dig to forage corpses, in one case digging down to eat the corpse of a buried horse that had died due to illness. They are known to eat animal cadavers by first ripping out the digestive system, which is the softest part of the anatomy, and they often reside in the resulting cavity while they are eating. On average, devils eat about 15 % of their body weight each day, although they can eat up to 40 % of their body weight in 30 minutes if the opportunity arises. This means they can become very heavy and lethargic after a large meal ; in this state they tend to waddle away slowly and lie down, becoming easy to approach. This has led to a belief that such eating habits became possible due to the lack of a predator to attack such bloated individuals. Tasmanian devils can eliminate all traces of a carcass of a smaller animal, devouring the bones and fur if desired. In this respect, devils have earned the gratitude of Tasmanian farmers, as the speed at which they clean a carcass helps prevent the spread of insects that might otherwise harm livestock. Some of these dead animals are disposed of when the devils haul off the excess feed back to their residence to continue eating at a later time. The diet of a devil can vary substantially for males and females, and seasonally, according to studies at Cradle Mountain. In winter, males prefer medium mammals over larger ones, with a ratio of 4 : 5, but in summer, they prefer larger prey in a 7 : 2 ratio. These two categories accounted for more than 95 % of the diet. Females are less inclined to target large prey, but have the same seasonal bias. In winter, large and medium mammals account for 25 % and 58 % each, with 7 % small mammals and 10 % birds. In summer, the first two categories account for 61 % and 37 % respectively. Juvenile devils are sometimes known to climb trees ; in addition to small vertebrates and invertebrates, juveniles climb trees to eat grubs and birds ' eggs. Juveniles have also been observed climbing into nests and capturing birds. Throughout the year, adult devils derive 16.2 % of their biomass intake from arboreal species, almost all of which is possum meat, just 1.0 % being large birds. From February to July, subadult devils derive 35.8 % of their biomass intake from arboreal life, 12.2 % being small birds and 23.2 % being possums. Female devils in winter source 40.0 % of their intake from arboreal species, including 26.7 % from possums and 8.9 % from various birds. Not all of these animals were caught while they were in trees, but this high figure for females, which is higher than for male spotted - tailed quolls during the same season, is unusual, as the devil has inferior tree climbing skills. Three Tasmanian devils feeding. Eating is a social event for the Tasmanian devil, and groups of 2 to 5 are common. Although they hunt alone, there have been unsubstantiated claims of communal hunting, where one devil drives prey out of its habitat and an accomplice attacks. Eating is a social event for the Tasmanian devil. This combination of a solitary animal that eats communally makes the devil unique among carnivores. Much of the noise attributed to the animal is a result of raucous communal eating, at which up to 12 individuals can gather, although groups of two to five are common ; it can often be heard several kilometres away. This has been interpreted as notifications to colleagues to share in the meal, so that food is not wasted by rot and energy is saved. The amount of noise is correlated to the size of the carcass. The devils eat in accordance with a system. Juveniles are active at dusk, so they tend to reach the source before the adults. Typically, the dominant animal eats until it is satiated and leaves, fighting off any challengers in the meantime. Defeated animals run into the bush with their hair and tail erect, their conqueror in pursuit and biting their victim 's rear where possible. Disputes are less common as the food source increases as the motive appears to be getting sufficient food rather than oppressing other devils. When quolls are eating a carcass, devils will tend to chase them away. This is a substantial problem for spotted - tailed quolls, as they kill relatively large possums and can not finish their meal before devils arrive. In contrast, the smaller eastern quolls predate much smaller victims, and can complete feeding before devils turn up. This is seen as a possible reason for the relatively small population of spotted - tailed quolls. A study of feeding devils identified twenty physical postures, including their characteristic vicious yawn, and eleven different vocal sounds that devils use to communicate as they feed. They usually establish dominance by sound and physical posturing, although fighting does occur. The white patches on the devil are visible to the night - vision of its colleagues. Chemical gestures are also used. Adult males are the most aggressive, and scarring is common. They can also stand on their hind legs and push each other 's shoulders with their front legs and heads, similar to sumo wrestling. Torn flesh around the mouth and teeth, as well as punctures in the rump, can sometimes be observed, although these can also be inflicted during breeding fights. Digestion is very fast in dasyurids and, for the Tasmanian devil, the few hours taken for food to pass through the small gut is a long period in comparison to some other dasyuridae. Devils are known to return to the same places to defecate, and to do so at a communal location, called a devil latrine. It is believed that the communal defecation may be a means of communication that is not well understood. Devil scats are very large compared to body size ; they are on average 15 centimetres ( 5.9 in ) long, but there have been samples that are 25 centimetres ( 9.8 in ) in length. They are characteristically grey in colour due to digested bones, or have bone fragments included. Owen and Pemberton believe that the relationship between Tasmanian devils and thylacines was `` close and complex '', as they competed directly for prey and probably also for shelter. The thylacines preyed on the devils, the devils scavenged from the thylacine 's kills, and the devils ate thylacine young. Menna Jones hypothesises that the two species shared the role of apex predator in Tasmania. Wedge - tailed eagles have a similar carrion - based diet to the devils and are regarded as competitors. Quolls and devils are also seen as being in direct competition in Tasmania. Jones believed that the quoll has evolved into its current state in just 100 -- 200 generations of around two years as determined by the equal spacing effect on the devil, the largest species, the spotted - tail quoll, and the smallest species, the eastern quoll. Both the Tasmanian devil and the quolls appears to have evolved up to 50 times faster than the average evolutionary rate amongst mammals. Reproduction Developmental steps in the maturation of Tasmanian devil young. The diagonal lines indicate the amount of time the changes take ; for example, it takes about 90 days for a devil to develop fur over all its body. Females start to breed when they reach sexual maturity, typically in their second year. At this point, they become fertile once a year, producing multiple ova while in heat. As prey is most abundant in spring and early summer, the devil 's reproductive cycle starts in March or April so that the end of the weaning period coincides with the maximisation of food supplies in the wild for the newly roaming young devils. Occurring in March, mating takes places in sheltered locations during both day and night. Males fight over females in the breeding season, and female devils will mate with the dominant male. Females can ovulate up to three times in a 21 - day period, and copulation can take five days ; one instance of a couple being in the mating den for eight days has been recorded. Devils are not monogamous, and females will mate with several males if not guarded after mating ; males also reproduce with several females during a season. Females have been shown to be selective in an attempt to ensure the best genetic offspring, for example, fighting off the advances of smaller males. Males often keep their mates in custody in the den, or take them along if they need to drink, lest they engage in infidelity. Males can produce up to 16 offspring over their lifetime, while females average four mating seasons and 12 offspring. Theoretically this means that a devil population can double on an annual basis and make the species insulated against high mortality. The pregnancy rate is high ; 80 % of two - year - old females were observed with newborns in their pouches during the mating season. More recent studies of breeding place the mating season between February and June, as opposed to between February and March. Gestation lasts 21 days, and devils give birth to 20 -- 30 young standing up, each weighing approximately 0.18 -- 0.24 grams ( 0.0063 -- 0.0085 oz ). At birth, the front limb has well - developed digits with claws ; unlike many marsupials, the claws of baby devils are not deciduous. As with most other marsupials, the forelimb is longer ( 0.26 -- 0.43 cm or 0.10 -- 0.17 in ) than the rear limb ( 0.20 -- 0.28 cm or 0.079 -- 0.110 in ), the eyes are spots, and the body is pink. There are no external ears or openings. Unusually, the gender can be determined at birth, with an external scrotum present. Tasmanian devil young are variously called `` pups '', `` joeys '', or `` imps ''. When the young are born, competition is fierce as they move from the vagina in a sticky flow of mucus to the pouch. Once inside the pouch, they each remain attached to a nipple for the next 100 days. The female Tasmanian devil 's pouch, like that of the wombat, opens to the rear, so it is physically difficult for the female to interact with young inside the pouch. Despite the large litter at birth, the female has only four nipples, so there are never more than four babies nursing in the pouch, and the older a female devil gets, the smaller her litters will become. Once the young have made contact with the nipple, it expands, resulting in the oversized nipple being firmly clamped inside the newborn and ensuring that the newborn does not fall out of the pouch. On average, more females survive than males, and up to 60 % of young do not survive to maturity. Milk replacements are often used for devils that have been bred in captivity, for orphaned devils or young who are born to diseased mothers. Little is known about the composition of the devil 's milk compared to other marsupials. Inside the pouch, the nourished young develop quickly. In the second week, the rhinarium becomes distinctive and heavily pigmented. At 15 days, the external parts of the ear are visible, although these are attached to the head and do not open out until the devil is around 10 weeks old. The ear begins blackening after around 40 days, when it is less than 1 cm ( 0.39 in ) long, and by the time the ear becomes erect, it is between 1.2 and 1.6 cm ( 0.47 and 0.63 in ). Eyelids are apparent at 16 days, whiskers at 17 days, and the lips at 20 days. The devils can make squeaking noises after eight weeks, and after around 10 -- 11 weeks, the lips can open. Despite the formation of eyelids, they do not open for three months, although eyelashes form at around 50 days. The young -- up to this point they are pink -- start to grow fur at 49 days and have a full coat by 90 days. The fur growing process starts at the snout and proceeds back through the body, although the tail attains fur before the rump, which is the last part of the body to become covered. Just before the start of the furring process, the colour of the bare devil 's skin will darken and become black or dark grey in the tail. The devils have a complete set of facial vibrissae and ulnar carpels, although it is devoid of anconeal vibrissae. During the third week, the mystacials and ulnarcarpals are the first to form. Subsequently, the infraorbital, interramal, supraorbital and submental vibrissae form. The last four typically occur between the 26th and 39th day. Three young devils sunbathing Their eyes open shortly after their fur coat develops -- between 87 and 93 days -- and their mouths can relax their hold of the nipple at 100 days. They leave the pouch 105 days after birth, appearing as small copies of the parent and weighing around 200 grams ( 7.1 oz ). Zoologist Eric Guiler recorded its size at this time as follows : a crown - snout length of 5.87 cm ( 2.31 in ), tail length of 5.78 cm ( 2.28 in ), pes length 2.94 cm ( 1.16 in ), manus 2.30 cm ( 0.91 in ), shank 4.16 cm ( 1.64 in ), forearm 4.34 cm ( 1.71 in ) and crown - rump length is 11.9 cm ( 4.7 in ). During this period, the devils lengthen at a roughly linear rate. After being ejected, the devils stay outside the pouch, but they remain in the den for around another three months, first venturing outside the den between October and December before becoming independent in January. During this transitional phase out of the pouch, the young devils are relatively safe from predation as they are generally accompanied. When the mother is hunting they can stay inside a shelter or come along, often riding on their mother 's back. During this time they continue to drink their mother 's milk. Female devils are occupied with raising their young for all but approximately six weeks of the year. The milk contains a higher amount of iron than the milk of placental mammals. In Guiler 's 1970 study, no females died while rearing their offspring in the pouch. After leaving the pouch, the devils grow by around 0.5 kg ( 1.1 lb ) a month until they are six months old. While most pups will survive to be weaned, Guiler reported that up to three fifths of devils do not reach maturity. As juveniles are more crepuscular than adults, their appearance in the open during summer gives the impression to humans of a population boom. A study into the success of translocated devils that were orphaned and raised in captivity found that young devils who had consistently engaged with new experiences while they were in captivity survived better than young who had not. Embryonic diapause does not occur. Guiler has reported that consecutive hermaphroditism ( sex change ) has occurred in captured devils, while Pemberton and Mooney recorded in 2004 the case of an animal with a scrotum and a non-functional pouch. In an apparent response to reduced competition caused by devil facial tumour disease, female devils in regions with the disease are now more likely to begin breeding at the age of one year. The disease has also led to the reproductive season being less well - defined, with births more spread out throughout the year. Litters born to mothers with DFTD have more female pups than male pups. A slow - release hormonal contraceptive implant for female devils is being developed and tested in a joint program between the Save the Tasmanian Devil program, the Zoo and Aquarium Association, the Taronga Conservation Society and the University of Sydney. This wildlife contraceptive program is aimed to help the devils continue with their wild behaviour by mating freely, but without certain females contributing too much to the next generation, which `` can have long - term genetic consequences for the insurance population ''. Contraceptive trials in male devils showed that their testosterone increased, instead of decreasing as other male mammals ' testosterone does. Early studies suggest that the female contraception has been successful, and the female contraceptive implants will be tested in the Maria Island insurance population. Conservation status An 1808 impression featuring the Tasmanian devil and a thylacine by George Harris Widespread across Australia in the Pleistocene, the Tasmanian devil had declined and become restricted to three relict populations during the mid-Holocene period around 3,000 years ago. Rock art and a single fossil near Darwin point to a northern population, and remains in the southeast signify a southeastern population ranging from the mouth of the Murray River eastwards to the vicinity of Port Phillip in Victoria. This population had contracted from northern Victoria and New South Wales. The rising sea levels in the Holocene also cut it off from Tasmanian populations. The third population was from southwest Western Australia. Fossil evidence from this last location has proven controversial. As with many native animals, ancient devils were larger than their contemporary descendants. In 1972, Mike Archer and Alex Baynes found a devil tooth at the foot of a cliff near Augusta in Western Australia and dated it to 430 ± 160 years of age, a figure widely circulated and cited. Australian archaeologist Oliver Brown has disputed this, stating that the authors ' uncertainty about the origins of the tooth casts doubts on its age, especially as other remains all date to around 3,000 years ago. The cause of their disappearance from the mainland is unclear, but their decline seems to coincide with the expansion across the mainland of indigenous Australians and dingoes. However, whether it was direct hunting by people, competition with dingoes, changes brought about by the increasing human population, who by 3000 years ago were using all habitat types across the continent, or a combination of all three, is unknown ; devils had coexisted with dingoes on the mainland for around 3000 years. Brown has also proposed that the El Niño - Southern Oscillation ( ENSO ) grew stronger during the Holocene, and that the devil, as a scavenger with a short life span, was highly sensitive to this. In dingo - free Tasmania, carnivorous marsupials were still active when Europeans arrived. The extermination of the thylacine after the arrival of the Europeans is well known, but the Tasmanian devil was threatened as well. Thylacines preyed on devils, and devils attacked thylacine young ; devils may have hastened the thylacine 's extinction. While the thylacine was extant, apart from hunting devils, it may also have put pressure on the devil for survival, by competing for scarce food and dens ; both animals sought caves and burrows. It has been speculated that devils may have become more predacious and presided over larger home ranges to fill in the vacancy left by the thylacine. Habitat disruption can expose dens where mothers raise their young. This increases mortality, as the mother leaves the disturbed den with her pups clinging to her back, making them more vulnerable. Cancer in general is a common cause of death in devils. In 2008, high levels of potentially carcinogenic flame retardant chemicals were found in Tasmanian devils. Preliminary results of tests ordered by the Tasmanian government on chemicals found in fat tissue from 16 devils have revealed high levels of hexabromobiphenyl ( BB153 ) and `` reasonably high '' levels of decabromodiphenyl ether ( BDE209 ). The Save the Tasmanian Devil Appeal is the official fundraising entity for the Save the Tasmanian Devil Program. The priority is to ensure the survival of the Tasmanian devil in the wild. Since 1999, all devils caught in the field have had ear biopsies taken, providing samples of DNA. As of September 2010, there are 5,642 samples in this collection. Population declines At least two major population declines, possibly due to disease epidemics, have occurred in recorded history : in 1909 and 1950. The devil was also reported as scarce in the 1850s. It is difficult to estimate the size of the devil population. In the mid-1990s, the population was estimated at 130,000 -- 150,000 animals, but this is likely to have been an overestimate. The Tasmanian devil 's population has been calculated in 2008 by Tasmania 's Department of Primary Industries and Water as being in the range of 10,000 to 100,000 individuals, with 20,000 to 50,000 mature individuals being likely. Experts estimate that the devil has suffered a more than 80 % decline in its population since the mid-1990s and that only around 10,000 -- 15,000 remain in the wild as of 2008. The species was listed as vulnerable under the Tasmanian Threatened Species Protection Act 1995 in 2005 and the Australian Environment Protection and Biodiversity Conservation Act 1999 in 2006, which means that it is at risk of extinction in the `` medium term ''. The IUCN classified the Tasmanian devil in the lower risk / least concern category in 1996, but in 2009 they reclassified it as endangered. Appropriate wildlife refuges such as Savage River National Park in North west Tasmania provide hope for their survival. Culling The first Tasmanian settlers ate Tasmanian devil, which they described as tasting like veal. As it was believed devils would hunt and kill livestock, possibly due to strong imagery of packs of devils eating weak sheep, a bounty scheme to remove the devil from rural properties was introduced as early as 1830. However, Guiler 's research contended that the real cause of livestock losses was poor land management policies and feral dogs. In areas where the devil is now absent, poultry has continued to be killed by quolls. In earlier times, hunting possums and wallabies for fur was a big business -- more than 900,000 animals were hunted in 1923 -- and this resulted in a continuation of bounty hunting of devils as they were thought to be a major threat to the fur industry, even though quolls were more adept at hunting the animals in question. Over the next 100 years, trapping and poisoning brought them to the brink of extinction. After the death of the last thylacine in 1936, the Tasmanian devil was protected by law in June 1941 and the population slowly recovered. In the 1950s, with reports of increasing numbers, some permits to capture devils were granted after complaints of livestock damage. In 1966, poisoning permits were issued although attempts to have the animal unprotected failed. During this time environmentalists also became more outspoken, particularly as scientific studies provided new data suggesting the threat of devils to livestock had been vastly exaggerated. Numbers may have peaked in the early 1970s after a population boom ; in 1975 they were reported to be lower, possibly due to overpopulation and consequent lack of food. Another report of overpopulation and livestock damage was reported in 1987. The following year, Trichinella spiralis, a parasite which kills animals and can infect humans, was found in devils and minor panic broke out before scientists assured the public that 30 % of devils had it but that they could not transmit it to other species. Control permits were ended in the 1990s, but illegal killing continues to a limited extent, albeit `` locally intense ''. This is not considered a substantial problem for the survival of the devil. Approximately 10,000 devils were killed per year in the mid-1990s. A selective culling program has taken place to remove individuals affected with DFTD, and has been shown to not slow the rate of disease progression or reduced the number of animals dying. A model has been tested to find out whether culling devils infected with DFTD would assist in the survival of the species, and it has found that culling would not be a suitable strategy to employ. Road mortality A road sign telling drivers that there may be devils nearby Motor vehicles are a threat to localised populations of non-abundant Tasmanian mammals, and a 2010 study showed that devils were particularly vulnerable. A study of nine species, mostly marsupials of a similar size, showed that devils were more difficult for drivers to detect and thus avoid. At high beam, devils had the lowest detection distance, 40 % closer than the median. This requires a 20 % reduction in speed for a motorist to avoid the devil. For low beam, the devils are the seventh worst in terms of detection distance, 16 % below the median. For avoidance of roadkill to be feasible, motorists would have to drive at around half the current speed limit in rural areas. A study in the 1990s on a localised population of devils in a national park in Tasmania recorded a halving of the population after a hitherto gravel access road was upgraded, surfaced with bitumen and widened. At the same time, there was a large increase in deaths caused by vehicles along the new road ; there had been none in the preceding six months. The vast majority of deaths occurred in the sealed portion of the road, believed to be due to an increase in speeds. It was also conjectured that the animals were harder to see against the dark bitumen instead of the light gravel. The devil and quoll are especially vulnerable as they often try to retrieve roadkill for food and travel along the road. To alleviate the problem, traffic slowing measures, man - made pathways that offer alternative routes for devils, education campaigns, and the installation of light reflectors to indicate oncoming vehicles have been implemented. They are credited with decreases in roadkill. Devils have often been victims of roadkill when they are retrieving other roadkill. Work by scientist Menna Jones and a group of conservation volunteers to remove dead animals from the road resulted in a significant reduction in devil traffic deaths. It was estimated that 3,392 devils, or between 3.8 and 5.7 % of the population, were being killed annually by vehicles in 2001 -- 04. In 2009, the Save the Tasmanian Devil group launched the `` Roadkill Project '', which allowed members of the public to report sightings of devils which had been killed on the road. On 25 September 2015, 20 immunised devils were microchipped and released in Narawntapu National Park. By 5 October, 4 had been hit by cars, prompting Samantha Fox, leader of Save the Tasmanian Devil, to describe roadkill as being the biggest threat to the Tasmanian devil after DFTD. A series of solar - powered alarms have been trialled that make noises and flash lights when cars are approaching, warning the animals. The trial ran for 18 months and the trial area had two - thirds less deaths than the control. Devil facial tumour disease Main article : Devil facial tumour disease Devil facial tumour disease causes tumours to form in and around the mouth, interfering with feeding and eventually leading to death by starvation First seen in 1996 in Mount William in northeastern Tasmania, devil facial tumour disease ( DFTD ) has ravaged Tasmania 's wild devils, and estimates of the impact range from 20 % to as much as an 80 % decline in the devil population, with over 65 % of the state affected. The state 's west coast area and far north - west are the only places where devils are tumour free. Individual devils die within months of infection. The disease is an example of a transmissible cancer, which means that it is contagious and passed from one animal to another. However, this tumour is not native to Tasmanian devils and is also characterised as a tissue graft that is able to pass between hosts without inducing a response from the host 's immune system. Short of a cure, scientists are removing the sick animals and quarantining healthy devils in case the wild population dies out. Because Tasmanian devils have extremely low levels of genetic diversity and a chromosomal mutation unique among carnivorous mammals, they are more prone to the infectious cancer. The Tasmanian devil 's major histocompatibility complex, or MHC, is particularly important in the mechanism of the cancer. MHC molecules are integral proteins in an immune system 's arsenal to fight diseases. In normal circumstances, the tumour graft should be recognised by these MHC proteins and induce an immune response. Because of the lack of diversity in these MHC 's, however, these molecules can not recognise the tumour as foreign. This allows the disease to be able to spread throughout a population without being threatened by the host 's own immune system, further facilitating its transmission. The loss of this diversity is thought to be due to the several population fluctuations of the Tasmanian devils that have occurred in the last several decades. When the population is reduced to a very low number, genetic variation can decrease, resulting in MHC molecules that are very similar in make up. Wild Tasmanian devil populations are being monitored to track the spread of the disease and to identify changes in disease prevalence. Field monitoring involves trapping devils within a defined area to check for the presence of the disease and determine the number of affected animals. The same area is visited repeatedly to characterise the spread of the disease over time. So far, it has been established that the short - term effects of the disease in an area can be severe. Long - term monitoring at replicated sites will be essential to assess whether these effects remain, or whether populations can recover. Field workers are also testing the effectiveness of disease suppression by trapping and removing diseased devils. It is hoped that the removal of diseased devils from wild populations should decrease disease prevalence and allow more devils to survive beyond their juvenile years and breed. Research published in the Proceedings of the National Academy of Sciences on 27 June 2011, suggests picking a genetically diverse breeding stock, defined by the genome sequence, for conservation efforts. In 2011, it was estimated that it would cost $11 million to preserve the Tasmanian devil species. Research by Professor Greg Woods from the University of Tasmania 's Menzies Institute for Medical Research has shown encouraging evidence for the potential development of a vaccine using dead devil facial tumour disease cells to trigger an immune response in healthy devils. Field testing of the vaccine is being undertaken as a collaborative project between the Menzies Institute for Medical Research and the Save the Tasmanian Devil Program under the Wild Devil Recovery program, and aims to test the immunisation protocol as a tool in ensuring the devil 's long term survival in the wild. In March 2017 it was reported that scientists have for the first time successfully treated Tasmanian devils suffering from the disease, by injecting live cancer cells into the infected devils to make their immune system recognise the disease and fight it off, in a breakthrough which is hoped to speed - up development of an effective vaccine that can be administered to devils in the wild. Relationship with humans At Lake Nitchie in western New South Wales in 1970, a male human skeleton wearing a necklace of 178 teeth from 49 different devils was found. The skeleton is estimated to be 7000 years old, and the necklace is believed to be much older than the skeleton. Archeologist Josephine Flood believes the devil was hunted for its teeth and that this contributed to its extinction on mainland Australia. Owen and Pemberton note that few such necklaces have been found. Middens that contain devil bones are rare -- two notable examples are Devil 's Lair in the south - western part of Western Australia and Tower Hill in Victoria. In Tasmania, local Aborigines and devils sheltered in the same caves. Tasmanian Aboriginal names for the devil recorded by Europeans include `` tarrabah '', `` poirinnah '', and `` par - loo - mer - rer ''. According to Fritz Noetling, the Secretary of the Royal Society of Tasmania in 1910, there was no evidence that Tasmanian Aborigines ate any carnivorous animals. Owen and Pemberton feel this may have contributed to the devil 's survival prior to European settlement. Convicts at the time when Hobart was being settled in made a meal of Tasmanian devils and it was claimed to be not unlike veal. It is a common belief that devils will eat humans. While they are known to eat the bodies of murder victims or people who have committed suicide, there are prevalent myths that they eat living humans who wander into the bush. Despite outdated beliefs and exaggerations regarding their disposition, many, although not all, devils will remain still when in the presence of a human ; some will also shake nervously. They can bite and scratch out of fear when held by a human, but a firm grip will cause them to remain still. Although they can be tamed, they are asocial and are not considered appropriate as pets ; they have an unpleasant odour and neither demonstrate nor respond to affection. Until recently, the devil was not studied much by academics and naturalists. At the start of the 20th century, Hobart zoo operator Mary Roberts, who was not a trained scientist, was credited for changing people 's attitudes and encouraging scientific interest in native animals such as the devil that were seen as fearsome and abhorrent, and the human perception of the animal changed. Theodore Thomson Flynn was the first professor of biology in Tasmania and carried out some research during the period around World War I. In the mid-1960s Professor Guiler assembled a team of researchers and started a decade of systematic fieldwork on the devil. This is seen as the start of modern scientific study of it. However, the devil was still negatively depicted, including in tourism material. The first doctorate awarded for research into the devil came in 1991. Tasmanian devil milk is being researched for its potential to resist superbugs. In captivity At Healesville Sanctuary, Victoria Early attempts to breed Tasmanian devils in captivity had limited success. The animal activist Mary Roberts, who was known for her work in presenting a less hostile image of the devil to the public and wrote about it in academic journals, bred a pair at Beaumaris Zoo which she named Billy and Truganini in 1913. However, although advised to remove Billy, Roberts found Truganini too distressed by his absence, and returned him. The first litter was presumed eaten by Billy, but a second litter in 1914 survived after Billy was removed. Roberts wrote an article on keeping and breeding the devils for the London Zoological Society. Even by 1934, successful breeding of the devil was rare. In a study on the growth of young devils in captivity, some developmental stages were very different from those reported by Guiler. The pinnae were free on day 36, and eyes opened later, on days 115 -- 121. In general, females tend to retain more stress after being taken into captivity than males. A plan to create `` insurance populations '' of disease - free devils has been ongoing since 2005. As of June 2012, the insurance population has reached a combined total of 500 animals and representing over 98 % of the genetic diversity of this species. Most of these devils are living in Australian zoos and wildlife reserves. Beginning in November 2012 however, in an effort to create a population that is both wild and disease - free, Tasmanian devils have been relocated to Maria Island, a mountainous island off the east coast of Tasmania. The Maria Island population has grown from a starting population of twenty - eight to 90 and experts will soon begin transferring healthy devils back to the mainland population. A study on the survival rates of the Maria Island population found that in contrast to other carnivores raised in captivity, the Tasmanian devils were not adversely impacted by being born in captivity when released on Maria Island. Tasmanian devils were displayed in various zoos around the world from the 1850s onwards. In the 1950s several animals were given to European zoos. In October 2005 the Tasmanian government sent four devils, two male and two female, to the Copenhagen Zoo, following the birth of the first son of Frederik, Crown Prince of Denmark and his Tasmanian - born wife Mary. Due to restrictions on their export by the Australian government, at the time these were the only devils known to be living outside Australia. In June 2013, due to the successes of the insurance population program, it was planned to send devils to other zoos around the world in a pilot program. San Diego Zoo Global and Albuquerque Biopark were selected to participate in the program, and Wellington Zoo and Auckland Zoo soon followed. In the United States, four additional zoos have since been selected as part of the Australian government 's Save the Tasmanian Devil program, the zoos selected were : the Fort Wayne Children 's Zoo, the Los Angeles Zoo, the Saint Louis Zoo, and the Toledo Zoo. Captive devils are usually forced to stay awake during the day to cater to visitors, rather than following their natural nocturnal style. There have been reports and suspicions of illegal trading in the past. In 1997, a devil turned up in Western Australia ; it had not escaped from any licensed keeper. During the 1990s there were internet sites in the US that were advertising devil sales, and rumours that some US Navy personnel had tried to buy them illegally during a visit to Tasmania. Cultural references The devil is an iconic animal within Australia, particularly Tasmania ; it is the symbol of the Tasmanian National Parks and Wildlife Service, and the former Tasmanian Australian rules football team which played in the Victorian Football League was known as the Devils. The Hobart Devils were once part of the National Basketball League. The devil has appeared on several commemorative coins in Australia over the years. Cascade Brewery in Tasmania sells a ginger beer with a Tasmanian devil on the label. In 2015, the Tasmanian devil was chosen as Tasmania 's state emblem. Tasmanian devils are popular with tourists, and the director of the Tasmanian Devil Conservation Park has described their possible extinction as `` a really significant blow for Australian and Tasmanian tourism ''. There has also been a multimillion - dollar proposal to build a giant 19 m - high, 35 m - long devil in Launceston in northern Tasmania as a tourist attraction. Devils began to be used in tourism from the 1970s, when studies showed that the animals were often the only things known about Tasmania overseas and suggested that they should therefore be the centrepiece of marketing efforts, resulting in some devils being taken on promotional tours. With their unique personality, the Tasmanian devil has been the subject of numerous documentaries, fiction and non-fiction children 's books. Royalties from Margaret Wild 's Ruby Roars, about a Tasmanian devil, are going to research into DFTD. A 2005 Australian documentary on the Tasmanian devil, Terrors of Tasmania, directed and produced by David Parer and Elizabeth Parer - Cook, follows a female devil called Manganinnie through breeding season and the birth and rearing of her young. The documentary also looks at the effect of devil facial tumour disease and the conservation measures being taken to ensure survival of the Tasmanian devil. It has screened on television in Australia and in the United States on the National Geographic Channel. Warner Bros ' Tasmanian Devil `` Taz '' at a parade in California The Tasmanian devil is probably best known internationally as the inspiration for the Looney Tunes cartoon character the Tasmanian Devil, or `` Taz '' in 1954. Little known at the time, the loud hyperactive cartoon character has little in common with the real life animal. After a few shorts between 1957 and 1964, the character was retired until the 1990s, when he gained his own show, Taz - Mania, and again became popular. In 1997, a newspaper report noted that Warner Bros. had `` trademarked the character and registered the name Tasmanian Devil '', and that this trademark `` was policed '', including an eight - year legal case to allow a Tasmanian company to call a fishing lure `` Tasmanian Devil ''. Debate followed, and a delegation from the Tasmanian government met with Warner Bros. Ray Groom, the Tourism Minister, later announced that a `` verbal agreement '' had been reached. An annual fee would be paid to Warner Bros. in return for the Government of Tasmania being able to use the image of Taz for `` marketing purposes ''. This agreement later disappeared. In 2006, Warner Bros. permitted the Government of Tasmania to sell stuffed toys of Taz with profits funnelled into research on DFTD. There is a DC Comics superhero called Tasmanian Devil who is a member of the Global Guardians team. Snarl, a character in the Transformers Beast Wars storyline, had the alternate form of a Tasmanian devil. Tasmanian Kid from Beast Wars II could also transform into a Tasmanian devil. Researchers have named a genetic - mutant mouse `` the Tasmanian Devil ''. It is defective in the development of sensory - hair cells of the ear, leading it to abnormal behaviours including head - tossing and circling, more like the cartoon `` Taz '' than the actual Tasmanian devil. For the 2.6. 29 release of the Linux kernel, Linus Torvalds temporarily replaced the Tux mascot with a Tasmanian devil named `` Tuz '', in support of the Save the Tasmanian Devil Campaign. The Devil Cat catamaran A catamaran, called the Devil Cat, was named for, and based on, the Tasmanian devil. Operating on the world 's longest distance high speed ferry service, the catamaran crossed Bass Strait between George Town in Tasmania, and Station Pier, at Port Phillip, Port Melbourne in Victoria, during 1997 -- 2002.
