Douroucouli - Capron Park Zoo Capron Park Zoo Central America to northern Argentina Habitat: Variety of forest types from sea level to 10,000 feet Average Size: Wild: Vegetable matter (shoots, fruit, flowers, leaves and sap), occasionally invertebrates, birds, frogs and bats Zoo: Produce, monkey biscuits, occasional treats like peanut butter and jelly Reproduction: Litter size: 1 infant Appearance: The Douroucouli is a smallish monkey with dense silvery-black fur covering most of the body. It head has large, dark eyes that are surrounded by light colored fur, giving it an owl-like appearance. Predators: Nocturnal raptors (such as the Great Horned Owl) and other arboreal carnivores. Population Status: Stable About the Animal: The Douroucouli, or owl monkey, is the only truly nocturnal monkey in the world, and the only nocturnal primate in the New World. Other nocturnal primates, such as lemurs, are found primarily in western Africa and Madagascar. Because of their nighttime habits, Douroucoulis are accomplished scent makers.

They have a gland at the base of the tail that secretes a smelly, oily substance. As they move through the trees, they rub this gland on branches. They also wash their hands with urine, thus spreading their scent as they walk, leaving behind a pungent trail of oil and urine wherever they go. Unlike many primates that live in troops, Douroucoulis are monogamous, living only in family groups. Each family group will defend its established territory against outsiders in an aggressive fashion. Even though they are nocturnal, in the coldest parts of their range Douroucoulis will forage in the daytime during the winter. Mating and Reproduction: Douroucoulis have not set mating season, and give birth throughout the year. Each litter will have one infant that is cared for by both parents. Offspring will remain in the family group for up to six years. Amazing Information: The ‘double-chin’ of the Douroucouli is actually and air pouch, which when inflated adds resonance and volume to the call.

The Animal Douroucouli - KidsBiology.com About Douroucouli The Douroucouli are among the most adorable of all animals because of their large eyes. These eyes are used for seeing at night. The Douroucouli monkey is a nocturnal monkey, meaning that it sleeps during the day, and searches for food at night. The Douroucouli eats insects and fruits. It has a small pouch under its throat, which it inflates when it calls out. What is this animal's name? Douroucouli What class is this animal assigned to? Mammalia What does this animal eat? Insects and fruit Where did this animal live? South America Mammals - Virginia Zoo in Norfolk Blog Mammals Meet some of the popular mammals living at the Virginia Zoo. In addition to these favorites, we have lots more mammals, too, so come see us soon. African Lion Our male lion, Mramba weighs 364 pounds, and has a laid back nature. Zola, the Zoo’s female lion, is Mramba’s mate. She weighs 344 pounds, is quick tempered and likes playing with balls and cones.

Our lions are very vocal, and their roars can be heard across the Zoo. African lions are found throughout the south Sahara desert and in parts of southern and eastern Africa. Lions are the only truly social cat species, and the only cats that live in large family groups. They spend their lives clustered into groups called prides, which consist of a single dominant male and several closely related females. Females hunt as a team to kill a communal meal. Males eat first, then the females, and finally the cubs. The male lion’s mane serves as form of intimidation by making him seem larger, and it also protects his throat from enemies. A lion is a “digitigrade” or toe walker – that means his heel does not touch the ground. Asian Small-Clawed Otter We have two Asian small-clawed otters: male Sawyer and female Merrill, that we are hoping will breed. The habitat features an underwater viewing area through which visitors can watch the otters swim. The Asian small-clawed otter is the smallest of the 13 species of otters found throughout the world. They are generally no more than two feet long and weigh less than 10 pounds.

The hind feet are fully webbed, while the front are only partially webbed, giving them the kind of flexibility found in “hands” rather than feet. These otters are carnivorous, eating mostly mollusks and crustaceans, but also frogs, fish and eggs. Asian small-clawed otters can be found in freshwater streams and rivers in southern India, China and the Philippines, and throughout Southeast Asia, but populations are declining due to habitat destruction, pollution and hunting. Asiatic Black Bear Also known as “moon bears,” because of the patch of white fur on their chest resembles a crescent moon. The Virginia Zoo has two Asiatic black bear brothers, Chai and Thai. Very active, they like to wrestle and can frequently be seen tearing up bamboo in the Moon bears are omnivorous and can be found throughout Southern Asia, Korea and northeastern China. Though similar in size to North American black bears, Asiatic black bears have a thicker mane of fur around their neck.ir habitat. Chai is the bigger of the two, weighing in at around 450 pounds. Binturong We have two binturongs: Rungus, a male, and Suzy, a female.

Sometimes called Asian bearcats, binturongs are not related to bears or cats; some people just thought they looked like a combination of the two animals. They are arboreal, and about half of their four to six foot body length is a long prehensile tail they use to help them climb through the trees. In the wild, they can be found in the upper tree canopy in rainforests in China, Inonesia, the Philippines and India. Binturong are omnivorous, eating fruit, leaves, small mammals, birds, invertebrates, carrion and eggs. Bongo The bongo is the largest and heaviest forest antelope. The bright chestnut color of its coat becomes darker with age until old males are almost black. The body is highlighted with 12 to 14 narrow white stripes on the shoulders, flanks and hindquarters. The large ears are believed to sharpen hearing, and the distinctive coloration may help bongos identify one another in their dark forest habitats. Both males and females have spiraled horns. Bongos are found in rain forest with dense undergrowth in the Lowland Rain Forest of West Africa and the Congo Basin to the Central African Republic and Southern Sudan.

They are timid and easily frightened. They will move away after a scare, running at considerable speed, even through dense undergrowth. Malayan Tapir Visitors to the Zoo often think our tapirs look like giant anteaters, or that they must be related to elephants, because of their prehensile nose. In fact, Tapirs are among the most primitive herbivores, dating back 20 million years and are most closely related to the horse and rhinoceros. In Thailand, tapirs are called “P’som-sett,” meaning “mixture is finished,” which refers to the local belief that tapirs were created from the leftover parts of other animals. Our two tapirs, our male Rimba and our female Hattie, enjoy bananas and taking a dip in their habitat’s small pond. Rimba was born in the Singapore Zoo and is very active for a tapir, often jogging laps around his habitat or chasing Annie. In the wild, tapirs can be found in the dense rainforests of Thailand, Myanmar, Malaysia and Indonesia. They are herbivores, eating grasses, aquatic vegetation, leaves, buds, soft twigs and fruits of low shrubs.

Excellent swimmers and divers, tapirs often breathe with their snouts poked above the water surface like a snorkel. Tapirs are endangered and their numbers are decreasing due to habitat destruction and fragmentation. Large scale deforestation, including illegal logging and the growth of palm oil plantations, is a major factor in the loss of their habitat. Malayan Tiger Christopher and cubs Stubbley and Osceola are our three Malayan tigers. Though obviously much larger and more dangerous, they exhibit many of the same qualities found in house cats, lounging in the sun, stalking potential prey and playing with toys. Malayan tigers are endangered and recent counts showed there may be as few as 400 left in the wild. It is perhaps the smallest subspecies of tiger, with an average weight of nearly 300 pounds for adult males and just over 200 pounds for females. In the wild, Malayan tigers mainly prey on deer and wild boar. They are found in the tropical forests of the southern and central Malay Peninsula. Masai Giraffe We have three giraffes at the Virginia Zoo: adult male Billy, older female Imara, and Noelly who arrived in April 2015.

Giraffes are the tallest land mammals, and that height allows them to see danger sooner than smaller animals. They also have excellent eyesight. They frequently are the first to start running when they sense danger is near, which is a signal to other animals nearby. Like most mammals, the giraffe has seven neck vertebrae. However, each can be over 10 inches long. Their tongues are over 18 inches long, and they are blue. The color helps prevent the tongue from being sunburned when they use it to pluck leaves from trees. Orangutan We have 4 orangutans at the Zoo; Schnitz, Pepper, Dara and Solaris. Schnitz, a male orangutan, and Pepper, a female, were actually playmates when very young, but spent some time apart at separate zoos before being reunited in 1995. They have been together since and came to the Virginia Zoo together in 2011. Both were zoo born and the outdoor habitat at the Virginia Zoo will be their first outdoor habitat.

Male orangutans can weigh as much as 300 pounds and stand up to five feet tall, while females are generally less than half that weight and stand about four feet tall. As males mature, they develop pronounced cheek pads of fatty tissue and acquire broad jowls and long beards. An orangutan’s arms can be more than six feet long, while the legs are 30 to 50 percent shorter. This body type suits an animal that spends most of its time swinging from branch to branch; a movement known as brachiating. They are omnivorous, eating fruit, young shoots, bark and insects. Orangutans once ranged throughout Southeast Asia and into southern China, and were found on the island of Java and in southern Sumatra. Orangutans are now found only on the islands of Borneo and Sumatra with the Sumatran species limited to the northern part of the island. Sumatran orangutans are fragmented into nine separate populations, all of which are located in the Indonesian provinces of Aceh and North Sumatra. Bornean orangutans are much more widely distributed and are found in Kalimantan, Sabah and Sarawak.

Their habitats include lowland and hilly tropical rain forests, mangrove and coastal peat swamp forests, and mountain forests. Red Panda Thomas, born on June 20, 2013, and Sunny can frequently be spotted exploring the trees and logs in their exhibit in Asia Trail of the Tiger. Timora, also known as Timmy, resides in the red panda habitat to the right of the path leading to the event field from fountain plaza. Red pandas, which resemble raccoons, are about 42 inches long with a long, bushy tail. Their soft, dense fur covers their entire body – even the soles of their feet. Red pandas use their long, bushy tails to help them balance when they are in the trees. They also cover themselves with their tails to keep warm in the winter. Red pandas live in the cool temperate bamboo forests in Sichuan and Yunnan Provinces in China, the Himalayas and in Myanmar. They share part of their range with giant pandas. Red pandas eat bamboo leaves, berries, blossoms, and bird eggs. Red pandas are endangered primarily due to habitat loss.

Red panda births are significant as they are a threatened species with fewer than 2,500 adults left in the world. Siamang The siamang is the largest member of the gibbon family. Like other primates, siamangs have four long fingers and a smaller opposable thumb. Their feet have five toes with an opposable big toe. Their arms are longer than their legs. Siamang are distinctive from other gibbons for two reasons: 1) Two digits on each foot are partially joined by a membrane and 2) A large gular sac which can be inflated to the size of its head, allowing the siamang to make loud resonating calls or songs. We have four siamangs, an adult male, Bali, and female, Hitam, and their offspring Lola and Guntur, who was born on November 21, 2014. They are acrobatic and agile, and can be seen leaping with confidence across formidable gaps between ropes or branches on Siamang Island, their outdoor habitat, or in their indoor playroom. Siamangs range through Southeast Asia and are found in some numbers on the Malay Peninsula and Sumatra.

They are arboreal, preferring the middle canopy level, but will travel from tree tops to low bushes while feeding. Like other primates, they are omnivores; though roughly half of their diet consists of leaves, siamangs also eat fruit, insects, nuts, small animals, birds and birds’ eggs. They are endangered and their numbers are declining as humans invade their habitat, often killing the mothers while capturing the young for a lucrative pet market. Slender-Tailed Meerkats Slate, a male, and Pat, a female, weigh about two pounds each and are very territorial. They are enthusiastic diggers, and their exhibit features extensive tunnels. Their other favorite pastime is to bask in the sun. Their favorite food is meal worms. Meerkats live in the Kalahari Desert in South Africa. They live in grass-lined burrows that they share with ground squirrels and yellow mongooses. However, they are very territorial with other meerkats and will fiercly defend their homes from other meerkat gangs also known as mobs. They are close knit with their own mob, and live in extended family structures. Security is an important concern, so they stand sentry and send out emergency calls to each other.

Squirrel Monkey This gang is curious and playful, swinging from the vines in their exhibit like professional trapeze artists. They weight between one and one and one-half pounds and are fascinated by mirrors. They also love marigolds and eating bananas. In the wild, squirrel monkeys live in big groups that include more than one male and lots of youngsters. Mothers carry the babies around on their backs. Their home range is east of the Andes from Columbia and northern Peru to northeastern Brazil. They live in forests and in cultivated areas, usually along rivers and streams. Squirrel monkeys’ tails are the same length or longer than the length of their bodies. They find safety in numbers by feeding in large groups that are too great for the larger monkeys to chase from the trees. White-Cheeked Gibbon We have two white-cheeked gibbons, Dexter, a male, and Asia, a female. Asia loves getting back scratches from her keepers. Dexter enjoys snacking on crickets and teasing the Asian small-clawed otters, with whom he shares his outdoor habitat. Male and female white-cheeked gibbons are so strikingly different in color that they look like different species.

Females have white fur, with a tiny patch of black on top of their head. Males are all black except for white patches on their cheeks. When baby gibbons are born, their fur is white like their mom’s (an effective form of camouflage), but they turn all black by one year of age. Then, as they become young adults, females turn white again, while males remain black. Adults are 18 to 25 inches tall and weigh about 12 to 20 pounds. White-cheeked gibbons are frugivores, eating eat mostly ripe fruits, but they also eat leaves and occasionally small invertebrates. In the wild they occupy the upper canopy of tropical rainforests and monsoon forests in Laos, Vietnam and southern China. White-cheeked gibbons are listed as Critically Endangered due to hunting and habitat loss. White Rhino Born in 1968, Alfred is one of the oldest animals at the Virginia Zoo. Alfred weighs 4,200 pounds and loves to play with toys like a large ball and barrel. He also enjoys wallowing in the mud. White rhinos are highly endangered, with less than 3,000 living in the wild.

Their horn is made of keratin, a fibrous protein that makes up human hair and nails. Rhinos have poor vision, but a very keen sense of smell. The white rhino is more placid and sociable than other types of rhinos. As the second largest land animal, typically a rhino yields only to an elephant. More Mammals Below is a list of many other mammals that make the Virginia Zoo their home. Most can be seen on exhibit, and some are popular Animal Ambassadors through the Education Department. You can meet Animal Ambassadors at Zoo special events, birthday parties, education programs and private parties. Come visit the amazing mammals at the Virginia Zoo!

Within the genus, there are two groups of owl monkeys, the gray-necked (lemurinus and subspecies, hershkovitzi, trivirgatus, and vociferans), found north of the Rio Amazonas (Amazon River) and the red-necked (miconax, nancymaae, nigriceps, azarae and subspecies), found south of the Rio Amazonas. Because this change in taxonomy was introduced fairly recently and is disputed, some published research continues to refer to the entire group as A. trivirgatus rather than distinguishing among species and subspecies.

It may be necessary to generalize about some of the characteristics of owl monkeys because of the confusion of taxonomy in the literature in addition to the limited published information about this taxonomic group. MORPHOLOGY: Separated into two groups based on their coloration, karyotype, and geographic distribution, owl monkeys have gray-tan to brown bodies and either gray or red fur on the sides of their necks. They have pale yellow to orange fur on their stomachs, underarms, and inner legs, light gray to white markings above and below their eyes, and three conspicuous, black stripes from the top of their head to either side of each eye and straight down the forehead between the eyes to the bridge of the nose. Their coats range in thickness and length depending on the altitudes at which they are found, with species living at higher elevations having thicker, shaggier coats than those living at sea level. They are unusual in their appearance compared to other primates because of their disproportionately large, brown eyes which have evolved as an adaptation to their nocturnal lifestyles. All owl monkeys are at least somewhat nocturnal and they are the only New World monkeys active at night.

While a nocturnal lifestyle is associated with primitive primates like prosimians, owl monkeys are not primitive but rather they re-evolved nocturnality from diurnal ancestors. Changes in the morphology of the eye and brain of owl monkeys reveal how specialized they have become to keep this nocturnal lifestyle but also reveal structural commonalities between other diurnal primates. To see objects in low light levels, owl monkeys have evolved large eyeballs, their lenses have a more spherical shape than is seen in diurnal primates, and there are also more rods and fewer cones. Though they do see in color, owl monkeys have less acute color vision than other primates. This is not a disadvantage as they are faster at locating and following moving objects at low light levels and have better spatial resolution at low light levels than other primates which helps them capture insects and move through arboreal habitat. There is very limited data on body size and weight for Aotus, most measurements from wild animals are extrapolated from only a few samples. Owl monkeys are not sexually dimorphic so males and females are about the same size and weight. Average male A. a.

azarae weigh about 1254 g (2.76 lb) while females average 1246 g (2.75 lb). Wild A. a. boliviensis males weigh, on average 1180 g (2.60 lb) while females are slightly heavier, having an average weight of 1230 (2.71 lb). The weights from one wild A. a. infulatus male and one female are 1190 g (2.62 lb) and 1240 g (2.73 lb), respectively, and data from one male and one female A. brumbacki reveal weights of 875 g (1.93 lb) and 455 g (1.00 lb). Data from wild A. lemurinus reveal an average male weight of 920.7 g (2.03 lb) and average female weight of 859 g (1.89 lb). The weight of one male A. nigriceps was 875 g and the average weight of two females was 1040 g (2.29 lb).

There is a fair amount of information available on the body weights of A. nancymaae and A. trivirgatus. A. nancymaae males weigh, on average, 794 g (1.75 lb) and females weigh 780 g (1.72 lb) while wild A. trivirgatus males weigh, on average 813 g (1.79 lb) and females average 736 g (1.62 lb) (Fernandez-Duque in press). The weights of wild A. vociferans and A. zonalis are also based on small sample sizes. Male A. vociferans weigh 697.5 g (1.54 lb) and there are no data for wild females while A. zonalis males have an average weight of 889 g (1.96 lb) and females weight 916 g (2.02 lb), on average. There are no data available for A. miconax.

Owl monkeys move quadrupedally on branches and vines in the forests in which they live and are skilled leapers, able to cross gaps in the canopy up to four meters wide. The maximum recorded longevity for a captive owl monkey is 20 years. The only data on their longevity in the wild comes from an A. azarae population where it is known that a male has lived at least 11 years. RANGE / CURRENT RANGE MAPS (IUCN REDLIST): Aotus azarae | Aotus hershkovitzi | Aotus lemurinus | Aotus miconax | Aotus nancymaae | Aotus nigriceps | Aotus trivirgatus | Aotus vociferans Owl monkeys are widely distributed across southern Central America and northern South America. A. lemurinus subspecies are found in Panama, northern Colombia, and northwestern Venezuela while A. hershkovitzi ranges only in Colombia. The other gray-necked species include A. trivirgatus, which occupies a range extending from eastern Colombia and southern Venezuela into part of northern Brazil and A.

vociferans, which is widely distributed across Colombia, northern Brazil, northern Peru, and eastern Ecuador. All of the gray-necked species live north of the Amazon River while the red-necked owl monkeys are found south of the Amazon. A. miconax is limited to a very small region in northwestern Peru; A. nancymaae occupies a small region straddling the Peru-Brazil border and is sympatric with both red-necked (A. nigriceps) and gray-necked species (A. vociferans); A. nigriceps is found in Brazil and Peru, and A. azarae subspecies are found in Paraguay, Argentina, southern Bolivia, and Brazil. Little research has been conducted on Aotus in the wild probably primarily due to the difficulty of studying nocturnal primates. Research on owl monkeys requires not only specialized forest skills, including the ability to maneuver through the forest at night and good auditory and nocturnal visual skills, but radio-tracking equipment as well (Sussman 2000; Aquino & Encarnación 1994).

Some of the intrepid owl monkey researchers and contributors to the knowledge of wild Aotus include Patricia Wright (Peru and Paraguay), Rolando Aquino and Filomeno Encarnación (Peru), and Eduardo Fernandez-Duque (Argentina). Captive studies of Aotus have been conducted at the New England Primate Research Center. HABITAT: Aotus species widely inhabit primary, secondary, and remnant tropical forests as well as seasonally deciduous scrub forest, subtropical dry forest, and gallery forest from Panama to Argentina and Paraguay at a wide variety of elevations from sea level to 3200 m (10,498 ft). Temperatures at higher elevations can be as low as 5° C (41° F) and in the Chaco of Argentina, night temperatures as low as -5° C (23° F) are tolerated by Aotus. They tend to inhabit areas of high plant species diversity with a relatively dense canopy and will forage at all canopy levels. In Peru, they specifically prefer two types of habitats: lowland forest that is flooded seasonally or highland forest that is never flooded.

In the flooded forest, where water can be as deep as seven meters (23.0 ft) during the rainy season, there is a predominance of trees with thickened trunks and branches that provide hollows used as sleeping sites, as well as pervasive growth of lianas and epiphytes, important plants used as sleeping sites and refuges. In Colombia, Aotus species are found in high, primary forests and in remnant and older secondary forests, but not in young secondary forests with low species diversity. In Argentina, Aotus is found in both high and low forests as well as gallery and island forests with dense canopies. In Brazil, A. infulatus uses a variety of habitats including coastal forests with palm trees, mangroves, and gallery forest. All of the habitats in which they are found exhibit seasonal patterns of rainfall and temperature changes, with the rainy season generally lasting from about September to about May and the dry season occurring during June through August. ECOLOGY: Aotus is the only nocturnal monkey.

Adopting a system of nocturnal behavior seems disadvantageous to animals like primates that have a high dependence on vision: food, including insects, animal prey, and fruit, is more difficult to find at night, locomotion through the forest canopy is significantly more dangerous in dim light, and a different set of environmental conditions such as cooler temperatures, differences in humidity, competitors, and predators pose threats. Despite these obstacles, the fossil record proves that owl monkeys assumed this nocturnal role from diurnal ancestors and, based on their wide geographical distribution, have been successful in exploiting this niche. Many of the ecological and behavioral characteristics of Aotus can be explained or at least linked to their unique pattern of life. Though most species of owl monkeys are nocturnal, A. a. azarae shows the particularly rare pattern of cathemeral activity in which it is regularly active during both daylight and nighttime hours. Because of its range in the very seasonal Chaco of Argentina and Paraguay, the ability to forage during daylight hours is probably an adaptation to avoid activity on extremely cold, moonless nights. Members of the genus generally leave their sleeping site about 15 minutes after sunset and return before sunrise each day.

After leaving the sleeping site, groups travel and feed until about midnight, when they stop to rest for 90 to 120 minutes. Owl monkeys are frugivores and supplement their diet with flowers, insects, nectar, and leaves. They prefer small, ripe fruit when available and in order to find these, they forage in large-crown trees (larger than ten meters [32.8 ft]). Seasonal availability of fruit varies across environments. Aotus species in tropical forests eat more fruit throughout the year because it is more readily available compared to the dry forests where fruit is limited in the dry season and owl monkeys are more dependent on leaves. It is difficult to quantify leaf and insect eating during the night, though, and researchers sometimes have to rely on fecal sample composition to project quantity and therefore importance to owl monkeys. Insect foraging occurs at dawn and dusk. Rather than seeking out insects in holes and crevices, owl monkeys are adept at grabbing flying insects out of the air or snatching them off of a branch. They most often eat large orthopterans, moths, beetles, and spiders and probably specialize in these because of the insects' rhythms.

Moths are active at night, orthopterans call loudly at night, exposing their location, and beetles are active at night are easier making them easier to see. After spending the night traveling, foraging, resting, and socializing, as dawn approaches owl monkeys increase their activity levels, and forage as they travel to either the same sleeping site from the previous day or another one within their home range. Sleeping sites are either tree holes or thickets of dense foliage made up of lianas or epiphytes and, if they are big enough, may be shared with other nocturnal animals like bats. Owl monkeys spend most of their time foraging and sleeping above in the high canopy, above ten meters (32.8 ft). Density of owl monkeys ranges from two to 16 groups per km² (.772 to 6.18 groups per square mile). Home ranges of owl monkeys are smallranging between .031 and .175 km² (.012 and .068 mi²), depending on the species.

The average nightly range is about of 708 m per night (.441 mi), but they use a larger area during the wet season, 829 m (.515 mi) per night and a smaller area during the dry season, 252 m (.157 mi). This use of space indicates that they spend more time resting and rely on fewer resources during the dry season, but resource availability is not the only factor influencing nightly travel distance. Nightly path length is also correlated with available light; the distance traveled is directly linked to the amount of moonlight on a given night. Owl monkeys travel twice as far on bright nights with full moons than on dark nights, and they concentrate their movement during the times of night with the most moonlight. Even though they do not travel as far, they still need to move on dark nights to find food and one adaptation to this need to forage is to travel the same routes repeatedly. They probably memorize routes and use chemical cues to help them find their way between food sites and sleeping sites.

Aotus azarae azarae : Though owl monkeys are sympatric with other primates that use similar resources, they do not compete for access to resources because of their alternative schedules. Furthermore, non-primate nocturnal competitors are usually small-bodied (like bats) or forage alone or in pairs, not posing a significant source of competition. Nocturnal predators do not usually eat monkeys, but some potential threats include owls, snakes, and felids. Diurnal raptors may pose a threat to owl monkeys if they are not well hidden in their sleeping sites. SPECIAL NOTES At any given time, there are about 150 to 200 million people worldwide infected with malaria and over a million children annually under the age of five die from this disease spread by infected mosquitoes. Owl monkeys have been successfully employed in biomedical research on malaria since the 1960s because of their natural resistance to the parasites that cause the disease. Individuals of some species are intermittently removed from the wild to bolster captive colonies for research, breeding programs, and zoos, but effects on the total population are not significant and the population can recover after these "cropping" events.

Weird Elusive Animals | strange true facts|strange weird stuff|weird diseases Weird Elusive Animals 0 Comments I love watching monkeys doing tricks, and all I know that chimpanzee, orangutan or gorilla are of the same kind. Then I came upon this article What-on earth, and I discovered that there are lot more various kind of monkey species. Hairy Saki Male hairy saki have more colorful heads, dark fur, bushy tail. Their nails on fingers and toes are convex, almost claw-like. They eat fruits, seeds, vegetable matters, insects, small birds and eggs and bats. They are found mostly in Orinaco river north of Amazon to the Guianas, except for the white-nosed sakis, which are restricted to an area south of the Amazon between the rivers of Madeira and Xingu.

Saki monkey have different kind of species like; Southern-bearded saki is known as Black-bearded saki, Black Saki otherwise called Saki satan or Humbold’ts sakis, Red-backed sakis or called Jew monkey, White-nosed bearded saki also called Saki a nez blanc in Brazil, Beardless saki, Monk saki and white-faced saki or pale-faced, matfaced or wanaku. Sloth Monkey Sloth Monkey They are also called, “Lazy animal” because of their very, very low movements of metabolism. The bulk of their diet are buds, leaves and tender shoots, mainly Ceropsia trees (locally known as yarumo ot yagrumo). Brazil sloths are small monkey. Prosboscis Monkey (Long-nosed Monkey) Proboscis Monkey (Long-Nosed monkey) Also commonly called in Malay language as Monyet Belanda or Bekantan in Indonesian language or simply called Long-nosed monkey. This reddish-brown is endemic found in South-East Asia of Borneo. Red-Faced Spider Monkey Red-faced Spider Monkey They are commonly called Guiana Spider Monkey or Red-faced Spider monkey, found in Northern South America.

Uakari Red Faced-Bald Monkey Uakari Red-faced Bald Monkey Found in Western amazon of Brazil and Peru. Red-faced bald headed Uakari monkey, have long shaggy coats, short bob-like tail. Scarlet red faced is due to lack of skin pigments and full of capillary that run under their facial tissue. Douroucouli Monkey or Owl monkeys Douroucouli Monkey or Owl Monkey Douroucouli monkey or Owl monkeys, also called Night monkeys, true nocturnal species of monkeys in the world. These night monkeys usually are active on the twilight periods when most species, are active in the early night. They are found in South America and sometimes in the central regions and you can hear them before you see them.
