orthacanthus is an extinct genus of fresh-water shark from a family of prehistoric sharks known as xenacanths .

members of the genus had a long spine growing from the back of their skull and a very long dorsal fin , which ran all along its back giving it an eel-like appearance .

its body reached nearly 10 feet ( 3 meters ) in length and the shark possessed a peculiar set of double-fanged teeth .

orthacanthus has yet to be readded to jurassicraft . until it is , this information can only be considered accurate for 1 . 7 . 10 and prior .
the practice , known as
fillial cannibalism ,
was identified thanks to evidence found in a shark coprolite — a fossilized piece of feces . as a study in the journal paleontology details , scientists from trinity college dublin discovered the presence of juvenile orthacanthus teeth inside an orthacanthus coprolite . ( the scientists know it ' s ancient orthacanthus poop because of its unique spiraling shape — that eel - shaped ancient shark actually had a corkscrew - shaped rectum which gave its feces an idiosyncratic form . ) mature orthacanthus grew to almost 10 feet ( 3 meters ) long , and was the apex predator of the swamps and bayous it inhabited .
paleontologists have found evidence that the extinct shark orthacanthus , which roamed swamplands and shallow seas some 300 million years ago , occasionally cannibalized its own young and pooped them out in fecal spirals through a corkscrew - shaped rectum . that ' s just how orthacanthus rolled , according to new research published in the journal palaeontology .
a number of species of orthacanthus shark have been described . these sharks , that possessed a long spine just in front of their sinewy dorsal fin , evolved in the devonian . orthacanthus fossils ( especially teeth ) are quite common in carboniferous rocks located in north america and europe . orthacanthus teeth fossils have been found in cumbria ( uk ) , close to the small port of whitehaven , a part of the coast we at everything dinosaur , know quite well . the sediments in that part of cumbria represent a coastal environment and amongst the carbonised remains of ancient plants , occasionally the distinctive tricuspid ( three pointed ) teeth of orthacanthus can be found .
“we don’t know why orthacanthus resorted to eating its own young . however , the carboniferous period was a time when marine fishes were starting to colonise freshwater swamps in large numbers . it’s possible that orthacanthus used inland waterways as protected nurseries to rear its babies , but then consumed them as food when other resources became scarce . ”
not only was orthacanthus very similar to the smaller xenacanthus ,  it also has a similar temporal range in the fossil record .  the two sharks probably coexisted with only the minimum of competition between the two .  this is because at only one meter long ,  xenacanthus could operate in waters that were too small or densely overgrown to support a three meter long predator like orthacanthus .  as the larger of the two ,  orthacanthus would have specialised in larger and more powerful prey that it would have seized with its double fanged teeth .  the overall eel like body morph of orthacanthus is a reflection of its habitat .  rather than being a pelagic open seas predator ,  orthacanthus hunted in freshwater swamps and waterways that would have been densely overgrown in areas .  by having a long body with short fins orthacanthus could navigate these waters without getting stuck in submerged debris and vegetation .  it ' s possible that orthacanthus may have used ambush tactics like lurking within the submerged debris and plants waiting for prey to pass by . the spike that rises up from the back of the head of orthacanthus seems to have been a defensive feature to stop other predators from clamping their jaws onto its head .  these exact predators may still be unknown to science but they may have been other fish like hyneria ,  or large amphibian tetrapods .
“orthacanthus was a three - metre - long xenacanth shark with a dorsal spine , an eel - like body , and tricuspid teeth . there is already evidence from fossilised stomach contents that ancient sharks like orthacanthus preyed on amphibians and other fish , but this is the first evidence that these sharks also ate the young of their own species . ”
these ancient shark turds were unearthed in minto coalfield in new brunswick , canada , and can be easily pegged as orthacanthus because of their recognizable spiraled shape . adult orthacanthus sharks could grow to as large as three meters ( 9 . 8 feet ) , and were apex predators in the swamps and shallow seas of the late carboniferous and early permian periods .
a new study suggests that orthacanthus sharks turned to cannibalism when food became scarce , with evidence of baby shark teeth being found in poop fossils unearthed from an old canadian coalfield .
it ' s possible that orthacanthus used inland waterways as protected nurseries to rear its babies , but then consumed them as food when other resources became scarce ,
he added .

though orthacanthus and other ancient sharks and fish developed to be euryhaline , or survive in waters with varied salinity , that might not have meant that there was enough food in the different ecosystems .
it ' s possible that orthacanthus used inland waterways as protected nurseries to rear its babies , but then consumed them as food when other resources became scarce ,
falcon - lang concluded .
the discovery was made by aodhán ó gogáin , a phd candidate at trinity college dublin ' s school of natural sciences , who found baby shark teeth in adult orthacanthus coprolites , or fossilized poop .
orthacanthus in jurassicraft is a hostile mob that will attack players , farm animals , squid , and other members of its own species . due to these cannibalistic tendencies , these fish cannot be kept in groups . the attack strength of the orthacanthus is pretty low ( slightly higher than that of a zombie or a spider ) , and it is only truly dangerous if the player is not wearing armour at all .
the preferred habitat of orthacanthus consisted of large bodies of freshwater , such as lakes , bayous and large rivers . it would ' ve been an apex predator in the many submerged coal - swamps of the carboniferous .
the fossilized poop , or coprolites , of orthacanthus shows baby teeth from their own young , which may mean that the ancient sharks resorted to cannibalism in tough times . the teeth are highlighted by a black box .
the fossil evidence for shark cannibalism comes from distinctive spiral - shaped coprolites ( fossil poop ) found in the minto coalfield of new brunswick , canada . the poop is known to have been excreted by orthacanthus because this shark had a special corkscrew rectum that makes identification easy . the poop is packed full of the teeth of juvenile orthacanthus , confirming that these sharks fed on their own babies . this is called
fillial cannibalism
.
fillial cannibalism has been observed in a number of extant shark species , including the bull shark ( carcharhinus leucas ) . the researchers suggest that orthacanthus may have filled a similar environmental niche as modern bull sharks . both types of shark are able to migrate backwards and forwards between salt and freshwater and in the case of orthacanthus , this unusual adaptation for a fish may have helped it play an important role in the colonisation of inland freshwater environments .

“it ' s possible that orthacanthus used inland waterways as protected nurseries to rear its babies , but then consumed them as food when other resources became scarce , ” said co - author howard falcon - lang , paleontologist at the royal holloway university of london , in a press release .
aodhán ó gogáin added :
orthacanthus was probably a bit like the modern day bull shark , in that it was able to migrate backwards and forwards between coastal swamps and shallow seas . this unusual ecological adaptation may have played an important role in the colonisation of inland freshwater environments .
the researchers theorize that the sharks began to cannibalize its own young not because it was an evil fish of the underworld , but because of lack of food resources . the orthacanthus was a euryhaline species , and as it moved into different aquatic ecosystem types , it may have run out of food .
a study of the coprolites of a prehistoric , freshwater shark suggest that this fish indulged in cannibalism when times were hard . the shark in question , an orthacanthus ( identified from the typical spiral shape of the fossil poo ) , probably ate members of its own species when other food resources became scarce .
: orthacanthus ' teeth were v - shaped . like most sharks , orthacanthus ' teeth were probably located in rows which rotated into use as they were needed . most sharks have about 5 rows of teeth at any time . the front set is the largest and does most of the work . the first two rows are used for obtaining prey , the other rows rotate into place as they are needed . as teeth are lost , broken , or worn down , they are replaced by new teeth . they did not chew their food like we do , but gulped it down whole in very large chunks .
about 260 million years ago , orthacanthus was the apex predator of freshwater swamps and bayous in europe and north america . it owned a peculiar set of double - fanged teeth . they first appeared about 400 million years ago in the devonian , and became extinct just before the mesozoic , about 225 million years ago .
we don ' t know why orthacanthus resorted to eating its own young ,
said study co - author howard falcon - lang , a researcher at the royal holloway university of london .
however , the carboniferous period was a time when marine fishes were starting to colonise freshwater swamps in large numbers .
finding juvenile teeth in ancient shark poop wouldn ' t have been enough on its own to suggest that orthacanthus resorted to cannibalism when other food sources ran low . after all , it ' s possible that some other carnivorous marine species was feeding on the baby sharks , and excreted the undigested teeth in their droppings .
orthacanthus was probably a bit like the modern day bull shark , in that it was able to migrate backwards and forwards between coastal swamps and shallow seas ,
said ó gogáin in a press release .
this unusual ecological adaptation may have played an important role in the colonisation of inland freshwater environments .
in a time long , long ago , say 300 million years ago , north america and europe were on the equator , covered in hot and humid swamps . many now - extinct fish species dominated the region , in particular the orthacanthus , a shark with double - fanged teeth that could grow up to 10 feet long .
within the fossils , there were loads of juvenile shark teeth . scientists think that this species , orthacanthus , lived in oily waters in swamps off the coast of europe and north america , surrounded by hot jungles . when nothing else was available , these top predators might have dipped into their own population to keep from going hungry .

orthacanthus is a genus of prehistoric freshwater shark that lived during the paleozoic era ( 400 - 225 mya ) . it was a member of a group of ancient sharks called xenacanths , all of which were freshwater sharks with long fins down their backs and a spine at the start of the fin . it was the largest of the known xenacanths .
scientist have known that around 260 million years ago , the orthacanthus was an apex predator in the swamps that would one day become the coal seams mined throughout the appalachians and western europe . but a new study in the journal palaeontology says that the top shark was not only eating all types of other species . it was eating its own children .
being fully aquatic , an orthacanthus egg can only be hatched underwater . like a vanilla minecraft squid , the fish can only survive for a few seconds out of the water ( word of warning : it may carelessly leap onto the bank when chasing you , so design its enclosure accordingly ) . in water , it will swim around randomly when idle .
we don ' t know why orthacanthus resorted to eating its own young . however , the carboniferous period [ roughly 360 to 300 million years ago ] was a time when marine fishes were starting to colonise freshwater swamps in large numbers ,
said one of the researchers , howard falcon - lang from royal holloway , university of london in the uk .
the group of international researchers studied fossils in new brunswick , canada , looking to focus in on ancient species’ euryhaline nature , or the ability of an organism to live in a wide range of water salinity types . but when they came across the fossilized feces of the orthacanthus , which is easy to spot from its corkscrew shape , the researchers found baby shark teeth inside .
dublin , ireland , thursday 11th august , 2016 - scientists have discovered macabre fossil evidence suggesting that 300 million - year - old sharks ate their own young , as fossil poop of adult orthacanthus sharks contained the tiny teeth of juveniles . these fearsome marine predators used protected coastal lagoons to rear their babies , but it seems they also resorted to cannibalising them when other food sources became scarce .
orthacanthus ( meaning
straight spine
) was a species of freshwater xenacanth shark that lived in europe and north america during the carboniferous and permian ( about 350 - 280 million years ago ) . it measured up to about 3 metres long , and was recognizable by a long spike extending from the back just in front of the ( very long and eel - like ) dorsal fin .
the coprolite fossil was discovered in a coalfield in minto , new brunswick , canada , but when the ancient shark roamed , that location was closer to the equator . at that time , freshwater rivers , coastal swamps and saltwater oceans all intersected , and paleontologists surmise that ocean fish like the orthacanthus started to use secluded freshwater spaces as nurseries , where young sharks were protected from other predators .
scientists think that orthacanthus sharks hunted in a range of shallow waters toward the end of the carboniferous period , so long ago that europe and north america lay on the equator . back then , the species was equally at home in the ocean and the swamps of the steamy jungle environments , called ' coal forests ' – as the remnants have now become compacted into coal seams over millennia .
orthacanthus is a genus of prehistoric freshwater shark that lived during the paleozoic era . it was also an member of a group of ancient sharks called xenacanths , all of which were freshwater sharks with long fins down their backs and a spine at the start of the fin . it was the largest of the known xenacanths at 3 meters ( 10 feet ) and 45 kg ( 100 lbs ) .
eating the young of one ' s own species is called filial cannibalism , in case you ' re wondering , and it is fairly common in the natural world , especially among fish . there are any number of reasons for it , ranging from paternal competition to sheer desperation . without any way to directly observe orthacanthus ' s baby - eating behavior , the motivations of these sharks remains hazy , but it ' s possible to speculate on what might have compelled them to dine on their children .
however , say the scientists , orthacanthus may have turned on its own young when other food sources in the freshwater swamps became scarce . and while the idea of prehistoric shark - eels consuming the flesh of their flesh may seem gruesome , it ' s not all that uncommon . animals killing and eating their own young , or the young of others of their species , may sound strange but it ' s not unheard of — the same behavior ' s been observed across the animal kingdom and in many mammals , from dolphins to bears and bonobos .
sharks not only dominated marine environments but they were also present in large numbers in brackish conditions and freshwater . one group of sharks , the xenacanthiforms were very common in freshwater environments and orthacanthus was a member of this group . fossil coprolites found in the minto coalfield of new brunswick , canada , reveal a dark secret . the 300 million - year - old shark poo is packed with the fossilised remains of juvenile members of its own genus . this is evidence of cannibalism , specifically fillial cannibalism – when adults of one species deliberately hunt and consume young of their own species , even their immediate offspring .

you know how people do that weird thing when a cute baby ' s nearby , where they tickle the baby and say things like ,
ooh , who ' s a cute baby ? who ' s so cute ? who ' s so cute i could just eat him up ?
according to a new study , an ancient precursor to modern sharks had the cutest babies around . ok , that ' s a bit of an extrapolation — and probably not an accurate one at that . but the study did show that around 300 million years ago , the orthacanthus shark engaged in the practice of feeding on its own young .

doesn ' t really look like many sharks alive today . its body was much longer and more slender and it had a shallow , rounded dorsal fin running from the back of its head all the way down to the base of its tail instead of the famous triangle fin we commonly associate with sharks . these physical characteristics gave it the appearance of an eel more than anything else but it was a true shark nonetheless . it also sported a long spike growing up from the base of its skull which may have been a defensive weapon against larger predators . it is this spike that gives the shark its name which translates to
vertical spike
. there are actually several kinds of living sharks that have spikes , too but all of theirs grow from the base of the dorsal fin , not the skull . orthacanthus ' s teeth grew in pairs or
twins
. this means that there were two pointy teeth coming out of one root .

aodhán ó gogáin , a phd candidate in the school of natural sciences at ireland ' s trinity college , uncovered an interesting new bit of information about a 300 - million - year - old shark .
new fossils of fecal matter found in canada revealed something a little unsettling : these sharks were feasting on their own young , possibly in times of low food supply . the findings were published on thursday in the journal palaeontology .
he said that they were probably similar to the bull sharks of today because they could survive in brackish swamps and shallow oceans . gogáin also mentioned that this may be part of the way fish started to colonize inland fresh waters .
another coauthor of the study , dr . howard falcon - lang of the royal holloway university of london , noted in the release that although the juvenile shark teeth were found in the fecal matter of adults , there is still some question as to why .
but , because the time that these sharks lived in was also the time in which marine fish were moving into freshwater locations , there might have been a decreased food supply for the sharks . this could have caused them to eat their own young for survival — an ironic twist on trying to keep the species alive .
it looks like this isn ' t the only time a species has been forced to cannibalize its own members in attempts to survive , however . recently , seagulls in washington state have started eating their own chicks , for example , because rising water temperatures have caused plankton , their main food source , to vanish .
so , while it may seem like an usually sinister phenomenon , cannibalistic ways appear to be a long - practiced final resort for animals who are trying to hold on in the face of changing environmental conditions .

three hundred million years ago , europe and north america lay on the equator and were covered by steamy jungles ( the remains of which are now compacted into coal seams ) . the top predators of these so - called
coal forests
were not land animals , but huge sharks that hunted in the oily waters of coastal swamps .
professor mike benton , university of bristol , is a co - author of the study . he said :
as palaeontologists cannot observe predator - prey relationships directly in the way that a zoologist can , they have to use other methods to interpret ancient food webs . one method is by probing the contents of coprolites [ fossil poop ] as we have done here .
the minto coalfield in canada , where the fossils were discovered , is of considerable historical importance , being the first place in north america where settlers mined coal in the early 17th century .

during the late carboniferous , much of the northern hemisphere was covered by swamps and ancient forests . amphibians and primitive reptiles dominated the land , but in the water , the fish reigned supreme and one group of fishes , that have survived through to today , the sharks , were particularly diverse and numerous .
fossil shark poo ( coprolite ) is not rare , it can be found in quite plentiful quantities in some bedding planes . shark coprolite comes in all shapes and sizes , but it often has a distinctive spiral pattern on it , an impression of the intestinal tract in which it was formed and of the rectum in which it was passed through . it is this spiral pattern that has permitted the scientists to identify the coprolite down to genus level in this instance .

shark week is over so lets say farewell to every nerd ' s favorite week of summer by checking out a truly fascinating - looking prehistoric shark . enter
! this shark actually lived in fresh water swamps throughout what is now the northern hemisphere as far back as the devonian ( 400 million years ago ) through the end of the permian era ( 260 million years ago ) . there are a few species within the genus ,
, but they are all relatively similar to one another . the fact that a genus of animal can last 140 million years is impressive
grew to about ten feet long and belongs to the family of sharks called xenacanths that was prevalent during this long time span .
likely was an opportunistic predator and probably hunted the many kinds of other fish as well as amphibians it shared its shallow freshwater environment with . it may also have periodically encountered the giant mammal - like reptile ,

that meal turned out to be another shark . a baby shark . and most notably , a shark of the same species .
the damning evidence - - the earliest we have of sharks eating members of their own species - - comes in the form of coprolites ( fossilized poop ) discovered in a coalfield in new brunswick , canada . scientists found 300 - million - year - old spiral - shaped feces that was
packed full
of the teeth of juvenile
because the shark ' s distinctive corkscrew - shaped rectum produced equally distinctive corkscrew - shaped poop , which makes identification
easy .
the question remains why the eel - shaped prehistoric shark turned to eating its own kind instead of its usual diet of fish and amphibians .
preyed on amphibians and other fish , but this is the first evidence that these sharks also ate the young of their own species .
we suppose starvation is as good an excuse as any for a shark to turn to filial cannibalism .

this is the first evidence that these sharks also ate the young of their own species ,
said researcher aodhán ó gogáin .
the evidence is pretty clear . there ' s no mistaking the juvenile teeth or the owner of the coprolites .
ó gogáin is the lead author of a new paper on the discovery , published this week in the journal paleontology . he likens the ancient shark to the modern bull shark - - both preferring to navigate back and forth between inland waters and shallow coastal seas .

food sources can do crazy things to an ancient shark ; recent research indicates changes in its prey may have caused the extinction of bus - sized shark megalodon .
an ancient shark that lived 300 million years ago was likely the most dangerous predator in its marine environment , and it looks like its fearsomeness wasn ' t just reserved for prey from other species .
but what most likely settles the identification issue is the shape of the fossil poop that the researchers found .
it also had a distinctive corkscrew - shaped rectum , and the coprolites ( fossil poop ) that the researchers discovered were indeed spiral - shaped – making it hard to avoid the grisly conclusion that these sharks ate their own young ( a practice known as filial cannibalism ) .
in any case , eating your own young is a relatively rare event in the animal world , for obvious enough reasons .
there ' s cannibalism and then there ' s specifically filial cannibalism . and that is relatively unusual ,
falcon - lang told jonathan webb at bbc news .
we generally find it in rather stressed ecosystems , where for whatever reason , food is running scarce . obviously , it ' s evolutionarily a bad move to eat your own young unless you absolutely have to .


the andaman shrew or andaman white-toothed shrew ( crocidura andamanensis ) is a critically endangered species of mammal in the family soricidae .

it is endemic to the south andaman island of india .

they are usually active by twilight or in the night and have specialized habitat requirements .

habitat loss due to selective logging , natural disasters such as tsunami and drastic weather change are thought to contribute to current population declines .

facts summary : the andaman white - toothed shrew ( crocidura andamanensis ) is a species of concern belonging in the species group
mammals
and found in the following area ( s ) : india .
this species was previously only known by the holotype of ' south andaman island ' , india in the eastern indian ocean . a single individual was collected on mount harriet , south andaman island ( das 1999 , hutterer 2005 ) .
this species is restricted to and known only from the holotype on middle andaman island ( andaman islands , india ) ( molur et al . 2005 ) . surveys by chakraborty et al . ( 2004 ) did not yield any specimens of this species .
this species was previously only known by the holotype of ' south andaman island ' , india in the eastern indian ocean . a single individual of this species was recently collected on mount harriet , south andaman island ( das 1999 ; hutterer 2005 ) .
this species is a nocturnal animal , that lives in the leaf litter of tropical evergreen forests of northern middle andaman island ( molur et al . 2005 ) .
comments : erroneously attributed to genus suncus by krumbiegel ( 1978 : 71 ) . the species was recently collected on mt . harriet , andaman isls ( das , 1999 )
justification : listed as vulnerable because it is known from only a single , small location ( northern middle andaman island ) , and habitat loss resulting from tsunami or storm events represents a plausible future threat .
justification : listed as critically endangered because its extent of occurrence of approximately 51 km² , all individuals are in a single location ( south andaman island ) , and there is continuing decline in the extent and quality of its habitat .

hymenopus coronatus , also called h. bicornis , is a mantis from the rain forests of southeast asia .

it is known by various common names including walking flower mantis and ( pink ) orchid mantis .

it is one of several species known as flower mantises from their resemblance and behaviour .

in the wild , h. coronatus can be found in malaysia .

hymenopus coronatus , or orchid mantis , like creobroter pictipennis , comes from india , the surrounding inslands , and east to thailand and malaysia .
flying insects such as flies , moths , bees and so forth can be used as food , since hymenopus coronatus can dexterously catch them mid - flight .
the orchid mantis , or hymenopus coronatus , is one of the most stunning insects on the planet . it’s famous ability to mimic an orchid , with deep pinks , purples and whites , it what has made the orchid mantis such a desirable species . the hymenopus coronatus originates from malaysia , however has slowly crept into captivity .
the females of hymenopus coronatus are quite aggressive against others and must therefore be kept seperately . the males are less aggressive and can be kept in groups when properly fed .

orchid mantis , or hymenopus coronatus , is a beautiful pink and white mantis with lobes on its legs that look like flower pentals . although this species does not live on orchids , it does look remarkably well like a flower or orchid . this species is very popular and loved as a pet because of its beautiful bright colors and amazing camouflage . in the wild hymenopus coronatus is found in malaysia .
hymenopus coronatus , better known as the malaysian orchid mantis , is one of the most popular and sought after mantid species in captivity . they can be found in indonesia , malaysia , and sumatra rain forests .
hymenopus coronatus is a rather calm species of mantis . they will often stay at one spot over days without much movement . when disturbed they partially react in a similarely calm manner , but sometimes will flee by running or jumping away .
what hingston had seen was not a carnivorous orchid , as he thought . but the reality is no less weird or fascinating . he had seen – and been fooled by – an orchid mantis , hymenopus coronatus , not a plant but an insect .
the distribution area of hymenopus coronatus spans starting at north - east india over thailand and malaysia to the southasian islands . there it has been found on bornea , java , sumatra and ambon . my specimen originated from java ( igm - nr . 125 ) .

hymenopus coronatus feed primarily on flying insects in their nature habitat , which is why they are usually found on flowers . this would normally consist of pollen feeding flying insects ( bees , wasps , moths , butterflies , etc ) , however this can be difficult to achieve in captivity .
hymenopus coronatus is a quiet kind of praying mantis . usually she stays waiting for a prey . sometimes it will hunt after a prey when they detect it . the adult males can be extremely skittish and hyperactive . the adult male will often ( try to ) fly away when disturbed .
some orchid mantises are totally white , whilst some have the pink / purple colourings . the actual colour of the mantis is very dependant on the environmental conditions , such as diet , lighting , humidity and surrounding . in the wild , regardless of colour , the hymenopus coronatus would typically be found on orchids , flowers and insect - attracting shrubs .

he orchid mantis ( hymenopus coronatus ) should be kept in an enclosure that is at least 3 times as tall as the mantis is long , and at least 2 times as wide as the mantis is long . the gender of your mantis is a very important consideration when deciding on what size enclosure to purchase . this is because as a adult , females can get up to 3 inches long , while males can be less than 1 inch long as an adult .

its basic color is white . however , the color of the plants on which it is reared can influence the pinks and greens . hymenopus coronatus has large lobes on the upper sides of the legs . the eyes protrude far from the head , as with creobroter . they are initially golden , but become ever brighter , until in the last stage it is a wine - red color . the males have , compared to the female , rather small fangs . they possess , however , longer antennae in proportion .
orchid mantid nymphs can be sexed as soon as l2 ( click here to see how ) . males will remain tiny after each molt while the female will continue to grow . adult male coronatus are incredibly tiny in bulk compared to the females . it is perhaps the most extreme sexual dimorphism seen in any species . it is beneficial to sex the nymphs asap to separate the males from the females . males will mature very rapidly and must be slowed down and females must be sped up to ensure proper breeding . females coronatus grow up to 3 inches long while the tiny males will barely pass 1 inch .
the malaysian orchid mantis or hymenopus coronatus , lives on top of the orchid blossoms in the rainforests of indonesia and malaysia . their camouflage is so perectly adapted to their surroundings that it is almost impossible to say were the plant ends and the insect starts . the orchid mantis is a relatively normal sized species of mantis . the females can get over 5 - 8 cm in length . the males can get over 3 - 4 cm in length and are earlier adult . for more praying mantis video ' s please visit my channel . visit urltoken for all the latest nature news and wildlife video ' s subscribe to my channel : urltoken my channel : urltoken my latest video ' s : urltoken
just like most mantids , coronatus molt upside down when the time comes . the nymphs will refuse food a day or two prior to molting and attention should be given to the humidity to ensure a proper molt . females will take 7 molts to reach adulthood and males will molt only 6 times…which is why it is very important to slow the males down while speeding up the growth of the females . as long as proper humidity is maintained , there should be no problems with molting . allow the mantid to dry out on its own and resume feeding 1 day after molting .
hi having bred plenty of hymenopus i would say that your pair are close enough to put together , these are quite an easy species to mate , but the first thing the female will do is try and lift her wings once the males jumps on and taps her , if the male is too light at this point he is a poor mate so the female flips him off and quite often eats him , so feed the males prior to pairing . i would also suggest that you do keep well gut loaded flying food in the pair whilst they are together ( this can be several days before they couple ) to avoid disappointment . regards graham & janice
mated coronatus females will lay their oothecae from days to weeks after mating . the oothecae are approximately 2 inches in length and are white in color at first , but change to a light brown after a day or 2 . these must be kept under the same conditions as the adults to avoid drying out . maintain the humidity at 80 - 90 % just like a normal nymph and keep the temperature at 80 - 85f and the 50 - 100 or so nymphs should hatch out within 5 - 6 weeks . the hatchlings will be red and black at first and will take on their white and pink colors after their first molt . keep the nymphs as this caresheet suggests and separate the nymphs after the first molt .
the orchid mantis is white with soft or bright pink accents . some individuals are completely white , others completely pink and yet others are somewhat of a mix . one mantis can change color in a matter of days , depending on the environmental conditions like humidity and light conditions . this species has lobes on its legs that mimic flower petals . its natural habitat consists of white and pink flowers in bushes and small trees . in this way the mantis can remain unseen for predators such as birds and at the same time can catch pollinating insects that are attracted to the flowers .
the first instar of the orchid mantis is dark orange with black legs and a black head . after the first molt the nymphs are white with hot pink accents . the amount of pink can vary a lot between individuals but also during the lifetime of one individual .
an adult female is approximately 6 to 7 cm long , while the male is only about 2 , 5 cm . this size difference is definitely not to be missed ! because the male is that much smaller , he also matures earlier than the female ( he does not need so much time to grow ) . the male and female also differ in appearance ; the adult male has white wings with a pink - orange body , almost no lobes on the legs and long wings , while the female can vary in color and has large lobes on the legs . on her back the female has a green spot , while the male does not have this green spot but rather a brownish spot .
the ideal temperature for the orchid mantis is about 28 ° c , but you can vary the temperature between 25 ° and 35 ° c . at night the temperature should be at least 18 ° c . if you want to mate a male and a female that where born at the same time , you need to slow down the development of the male . these males should be constantly kept at 18 ° c .
this species needs a relatively high humidity . approximately 60 to 80 % rh . the nymphs are better kept drier , they are very sensitive to a humid environment . you can mist the nymphs about 1x per week , also depending on the ventilation you have in their enclosure . as the nymphs get older , you can gradually increase the air humidity by spraying more often .
as with all types praying mantids , this species needs an enclosure that is at least 3 times the length of the mantis in height , and at least 2x the length of the mantis width . for an adult female this means is at least 24 cm in height and 16 cm in width . a nice size for a terrarium would be 30 x 20 x 20 cm ( hxwxl ) , so there is room for many artificial flowers and perches .
you can not keep orchid mantises together in one enclosure when they are older than l3 . it is therefore strongly advised to house these nymphs separately . especially because of the size differences between males and females , cannibalism is very common .
because this species lives on flowers , it eats mainly flying insects in nature . it is advisable to also offer them flying insects in captivity . wild butterflies and hoverflies can be given in addition to a diet of houseflies / blue bottle flies . crickets may also be fed , but preferably not as a main food .
the females of this species are much larger than the males . it is therefore very important that the males and females identified in time , so you can make adjustments to their developmental time . if you want to mate males and females that were born around the same time , you need to slow down the development of the males . if you do not , then the males have already died of old age while the females are not yet mature . you can determine the sex of a mantis by counting the segments on the abdomen , as described here . once you know what the males and the females , you should start treating them differently . the females must grow much more , to reach their large adult size , so they should eat as much as they want every day . the temperature may be very high for them , around 35 ° c . males have to be inhibited in their growth . give them small prey , and a lot less than the females . they should also be kept much cooler than the females , at about 18 ° c to 20 ° c . much lower temperatures cause health problems , so it is best to inhibit the growth primarily by food . of course you do not want to starve your males , so keep a good eye on their body condition . if you see that the females are almost adult , you can start to treat the males the same as the females . the females live much longer than males , so it is not a problem at all to have the female mature before the male . if you do not plan to breed the species you can keep males and females just the same all the time .
approximately 2 to 4 weeks after the last molt , a mating attempt could be made . make sure the female has eaten very well before you introduce the male . usually the female is very hungry and can eat the male in an instance . it is certainly advisable that the female has something to eat when the male is introduced . she is occupied with having dinner so the male can approach her relatively safe . mating may take several hours to even a few days . as long as everything looks good you can leave the male on her back for as long as he wants . when he leaves her back , remove him from the enclosure to make sure he is not eaten .
as described by their name , the orchid mantis look like… an orchid . with white / pink projections over their legs , neck , and abdomen , they can make a fantastic camouflage when placed on an orchid . males are distinctively smaller than females , with a much thinner body and less bulbas abdomen .
as adult , both species possess fully grown wings , and the male can fly very well . females can reach up to 6cm , wild caught specimens usually being slightly longer . males will reach a maximum of 3cm , and are mostly under half the length of the female ! this is the easiest way of determining sex , but can also be done by using the usual method , 8 segments for the male , and 6 or 7 for the female .
being a tropical species from malaysia , in captivity you will need to replicate these conditions for the orchid mantis as closely as possible . generally this means a fairly high humidity ( around 60 - 70 % ) , and relatively high temperatures between 25 - 35c . the ideal temperature is in the middle – around 28c . nighttime temperatures can drop to around 18 - 20c .
males typically mature faster than females , so keep males at a cooler temperature ( around 20c ) will slow their growth if you’re looking to achieve adult stages at a similar time .
whilst high humidity is recommended for larger nymphs and adults , the nymphs will be better suited to lower humidities – death in young orchid mantis nymphs can often be as a result of over spraying . as a result you should spray the enclosure just once every 5 - 7 days .
enclosures should be well ventilated to allow a good flow of air , and to allow stagnant air to dissipate . as with most mantis enclosures , it’s recommended to have at least 1 mesh or net side on your orchid mantis enclosure – this is usually done with either the top of the enclosure or a mesh / net door on the front . either way is fine ( or any way ) , just as long as there is ample ventilation , and not a sealed unit .
in terms of height and width , the enclosure should be at least 3 times the length of the mantis in height to ensure ample room for skin shedding , and at least 2 times the length in width . the addition of extra branches and artificial flowers makes for a much more attractive enclosure .
bluebottles and greenbottles can be the easiest food types ( you can buy maggots from tackle shops and hatch them out , allowing the flies to feed on a honey mixture to gut load them slightly ) . but any other flying insects found outside or inside would be gladly received by the orchid mantis .
young nymphs will happily feed on fruit flies , but larger pray will need to be introduced after l3 / 4 stage .
if flying pray isn’t achievable , then you can feed on crickets or locusts – but this is not recommended as a staple .
there have been many accounts of live food eating the mantis , so any food which has not been consumed within a day or so , should be removed .
as mentioned above , the growth of the males and females will be very different , with males growing at a much faster rate . therefore if you want to successfully mate your orchid mantis pairs , you will need to keep the males at a much lower temperature , and try to slow down the feeding cycles so the females are eating more .
around 3 weeks after the final moult into adult , you can then introduce your male to the female . as a much larger , more aggressive specimen , the female orchid mantis should be well fed , and ideally eating at the time the male is introduced .
orchid mantis ootheca will vary hugely in size , but you can expect to hatch up to about 90 young , all of which will emerge as jet black and red , skittish nymphs . even from young nymphs , orchid mantis are very ferocious when feeding , and will happily eat prey the same size – or bigger – when offered .
once he has picked up her pheromones , he should make an advance and attempt to start mating .

the orchid mantis is a praying mantis , which has got its name because it resembles the flower of an orchid with its four walking legs resembling flower petals . most orchid mantises are white , but there is also a pink to purplish colour morph .
did you know ? that as 1st instar hatchlings , orchid mantises resemble ants with black bodies and red legs ? only after they have shed their skin one time ( 2nd instar ) , they become white . after a few more sheds , they will get their final colour , white or or pink , males with a brownish - purple
necklace
, and females with a green necklace .
only four specimens reported to isis by one institution , which definietly does not reflect reality .
for air transport of adult individuals , container note 62 , for caterpillars container note 63 , of the iata live animals regulations should be followed .
zoos keep the orchid mantis for educational reasons because looks almost like the orchids it sits on . this ability to
hide in plain sight
helps the insect survive in its rainforest habitat . this kind of camouflage in which a species appears similar to its surroundings , is called mimicry .
the mantis comes to us when we need peace , quiet and calm in our lives .
they originate from india , the surrounding islands , and east to thailand and malaysia . orchid mantids are one of the most beautiful mantids in the world . the oothecas take 2 month to hatch . the temperature should be kept at 30 - 35c during the day time . at night , the temperature should not fall under 20°c and is best at 25°c .
diet : drosophila , houseflies , crickets , flour worms . the feed must be very diversified . to the newly hatched larvae must be promptly offered drosophila flies .
the enclosure must also have adequate ventilation , and some kind of material on the ceiling of the enclosure which will allow the mantis to hang upside down during molting , as well as an empty space at the top which is at least 2 times the size of the mantis . they can be kept in glass or mesh cages , but enclosures with glass or clear plastic sides and a mesh or screen top are ideal , due to the humidity requirements of this species .
orchid mantises are native to the tropical rainforests of malaysia , so they generally need warm , humid conditions to thrive . the ideal temperature for an orchid mantis is 80°f to 85°f , but they can tolerate a range between 70°f and 90°f . humidity should be kept above 60 % relative humidity ( rh ) , though younger nymphs seem to be less tolerant of higher humidity levels than adults . nymphs should be kept at the lower end of the range of humidity , between 60 % and 70 % rh . ventilation is also very important in the nymph stage . l1 nymphs in particular should be kept in a well - ventilated enclosure , with a top that allows for good air flow .
depending on the amount of ventilation , the enclosure should be given a light misting once a day . orchid mantises kept in mesh or screen cages should have their enclosures misted twice a day to maintain proper humidity . not only that , but misting the enclosure also allows the orchid mantis to drink . most mantises do not like getting sprayed directly , so it is best to try and spray around the mantis , but if you get them a little wet by accident , it is usually no big deal . use spring water , distilled water , or water filtered by reverse osmosis ( ro ) , but do not use plain tap water .
l5 nymph to adult : should be fed house flies , hover flies , blue bottle flies , butterflies , and moths .

the orchid mantid has been incredibly elusive in the pet trade . it is due to failed breeding and a ban on collection of wild specimen that contributes to its rarity . it is indeed a gem of the mantid kingdom . this infamous mantid lives up to its name like no other . it mimics the orchid flowers of its native origin and even the flower’s color . their color ranges from pink to white to red and even green . each leg sports a semi - circular lobe that gives the mantid its petal - like appearance . when threatened , the orchid mantid will flatten itself and spread its lobed legs outward to make itself look like a flower . adult males are white in color with brown markings and adult females are white with brown or green markings .
orchid mantids need high humidity , especially for nymphs of all stages . although a drop wont harm the mantid , it is best to maintain the humidity at 80 - 90 % . temperature varies on a wide scope . males that are being slowed down can be kept at 15 c ( roughly 60 f ) and females that are being sped up can be kept at 30 - 33 c ( 86 - 91 f ) . the more heat they are exposed to , the faster they will grow…but take care to not cook the mantid .
keep the orchid mantid nymphs in a small container lined with paper towel at the bottom…once they’ve outgrown their container ( be warry that they still have room to molt ) , move on to larger containers , but keep it small to make feeding easy . once they are well past l6 , terrarium substrate may be used to replace paper towel . as always , be sure to give the mantid proper room to molt . the suggested size is an enclosure with length , width , and hight that is at least 3x the mantids length . for example , a 1 inch mantid should not be kept in any cups or other enclosures smaller than 3x3x3 inches . i have heard that this species can be kept communally . i myself have not tried this and would not recommend it .
orchid mantids are not very picky , but good nutrition is necessary to breed them properly . feed them copiously with flying insects such as moths and flies and so on . these can be fed honey or sugared water prior to feeding to give the mantid additional nutrients . be sure to stay away from insects that can seriously harm the mantid . wasps and bees are not recommended unless the stinger has been removed…even then , bees do not have that much juice in them anyway so the mantid will just be eating a shell ( i’ve tried it ) . hatchlings may start out with fruit flies and graduate to house flies as they grow older and eventually moths and larger prey . crickets can be used if given proper nutrients prior to feeding , but an occasional cricket or two will not harm the mantid .
after 2 weeks since their last molt ( the “2 week” rule mostly applies to females , males can be bred within 1 week ) , introduce the female into the male’s cage . make sure that the female is very well fed and continue to feed her while she’s with the male . males are not easily coaxed into mating so he must be allowed to take things on his own terms . the male will occasionally drum on the female with his arms while courting and if the female is mature , she will allow him to copulate with her . you can try manually introducing the male onto the female’s back , but the males are very skittish and this may be too difficult . once copoulation is complete , remove the female and place her in a container for her to lay her oothecae . she may be re - bred after laying 2 or 3 oothecae to increase fertility in the last few oothecae , but it is not necessary .

the males reaching about 2 , 5 cm are significantly smaller than the females and are much less robust . meso - and metathorax including the walking legs and the wingbases are light brown . the rest of the habitus is similar to that of the female .
the sexes of juveniles can be distinguished be counting abdominal segments ( 8 for males , 6 for females ) . older larvae can be sexed by size .
the preying habits of this species are paticularely interesting . flying insects will be caught mid - flight without a problem . groundliving prey will be cunningly stalked with slow and rhythmic movements . the last centimeters will be reached by stretching and bending forwards to catch the prey with the raptorial legs .
the wings are rarely used in the terrarium ( that goes for both sexes ) . the males however , are excellent flyers when there is enough space , so be careful when taking them out of the container . females can not fly , the wings are at the most used to aid in longer jumps .
due to the mimesis it is a good idea to introduce flowering plants into the container . one can however not expect them to actually sit on the flowers , since most mantids just seek out the highest place possible ( in most cases the ventilation mesh ) .
raising the larvae is rather easy . when kept as mentioned above , the animals should develope without a problem . just keep in mind to seperate the females as soon as possible to avoid cannibalism . with some practice sexing can be done starting at the 3rd to 4th larva stadium .
breeding these animals is a little more difficult . since the males molt some times less than the females , it can happen that the males drop dead before the females reach adulthood . therefore one should keep the males much cooler ( 20 to 22 °c ) after a certain age and feed them less often . this reduces their speed of developement . when the females are subadult one can again keep the males regularely to make sure they reach adulthood together with the females . an ideal point in time is with or about one week after the females .
when the females are sexually mature and ready for mating ( about 2 to 3 weeks after the last molt ) , they will start to spray pheromones . to achieve this , they will bend their abdomen downwards and one can observe rhythmical pumping movements . now is the time to place the male behind or on top of the female ( the males are ready for mating about 1 week after the last molt ) . the male will then start to drum on the female to calm it and raise the mood for mating , using its raptorial legs . soon after the male will insert its abdomen into the genital opening of the female to pass the spermatophore . after a successful fertilization the female can lay about 2 to 3 oothecae . i have never seen them laying more then 4 . the oothecae will be placed on smooth surfaces , almost never on twigs .
the oothecae should be yielded at about 30 °c during day and 20 °c during night . 4 to 6 weeks later about 20 to 30 young will hatch , but i have had oothecae with little more then 50 young . the young should then be fed with drosophila hydei , but starting at about l3 houseflies can be fed , too .
the larvae are quite variable in color . in l1 the are colored orange with a black head and extremities . this ant minikry is lost one molt further and from there on they are colored in the usual white . they can be completely white or even pink . the pink coloration can mainly be seen on tibiae of the raptorial legs , the femora of the walking legs and the rear part of the abdomen . this pink coloration is lost when they molt into adulthood . the rear part of the pronotum of the young is colored green , will get darker over time and reach a brown in the adults .
this beautiful and rather easily kept species is good for beginners . it is much more difficult to keep the breeding over several generations . the need for space of the females can be a bit problematic too , since they must be kept seperately .

it lives as the name already says , mainly amidst orchids , but also on other colorful , large - petaled plants , on which it ambushes flying , nectar - seeking insects .
the small males remain distinctly smaller at 3 - 4 centimeters . the female is double that size getting as large as over 7 centimeters .
drosophila , houseflies , crickets , flour worms . the feed must be very diversified . to the newly hatched larvae must be promptly offered drosophila flies .
further pictures of this type can be seen in our picture gallery . questions , suggestions and criticisms can be sent directly to me .

hiding within this picture lies one of the world’s most stealthy creatures . it also has an awesome super power .
hiding within the majestic petals of a patch of orchids in the tropical rainforests of southeast asia lies one of the world’s most stealthy creatures .
for decades , humans believed the orchid mantis was hiding within the petals of these orchids , fleeing from the many dangers lurking on the forest floor in malaysia .
but a new exhibition at the melbourne museum is sharing incredible new insight which has changed what we thought we knew about these beautifully disguised creatures .
what australian scientists learned about these surprisingly uncommon creatures is that instead of hiding within these petals , ambushing bees and flies , they have become finely adapted for camouflage , mimicking parts of the orchid flower in an extraordinary display of predatory behaviour .
in fact it’s killer moves are now described as “pure ninja stealth” and scientists believe the insect is even better at catching pollinators than orchids themselves .
“this [ the orchid mantis ] is one of our big hero bugs , ” dr phil sirvid , entomologist at the museum of new zealand te papa tongarewa , who worked in conjunction with melbourne museum for the exhibition , told news . com . au .

the orchid mantis , hidden in the flower of a pink orchid , uses its front legs , covered in dagger - like spines , to spike its prey .
according to melbourne museum , its bug lab : little bugs , super powers exhibition allows museum visitors to “get up close and personal with real bugs including stick insects , beetles , snails , spiders and learn about their habitats , life cycles , social lives and how much humans depend on them” .
the orchid mantis is highlighted in the exhibition because of its deceptive imitation of the texture and colour of the orchid’s petals .
it remains completely still as it camouflages itself , only rotating its head to suss its surroundings .
“for decades we thought it was hiding and ambushing bees and flies , ” dr sirvid said .
dr sirvid explains that when a bee flies around looking for pollen , the way the flower looks to us is different to the way the flower looks to the bee .
flowers signal to bees using pollen and nectar , but the orchid mantis has found a way to override this signal with its own .
“what the orchid mantis is doing is outshining the flowers , providing more of a reward for the bee , and the bee will fly into the orchid mantis . it’s the last mistake it will ever make . ”
it turns out the mantis was never hiding at all , it was in fact , trapping .
“to a bee , the mantis looks like the best flower around . it’s like a hack , the bee is perceiving the uv shine of the mantis as a promising reward . but it will be anything but . ”
any pollinating insect , including flies , butterflies and moths , will all be fooled in just the same way as the bees .
once it has its prey right where it wants it , the orchid mantis uses its front legs , covered in dagger - like spines , to spike its prey .
“they’re such a wonderful looking insects , it’s a nice science , because for years people thought it was hiding , then people like james [ o’hanlon , an australian scientist ] flipped what we thought we know on its head . ”
— bug lab : little bugs , super powers is on from 23 june — 15 october 2017 at the melbourne museum . find more information here .
