The aye aye is a highly unusual primate that was originally classified as a rodent, until further research was done on this bizarre creature. The tails of these unique creatures are black or brown in coloration, and the body of the aye aye is generally brown or a slate color, with small flecks of white on the thick hair coat. The aye aye looks more like a rodent, than a primate at first glance, with its long, bushy tail that exceeds the length of its body. An aye-aye clings to a palm in eastern Madagascar. Aye-ayes tap a long finger on tree bark, feeling for the vibrations of insect larvae. The aye-aye lives a secretive life high up in the trees, and has few natural predators. The Fossa (Cryptoprocta ferox) is known to prey on aye-ayes, and the young are vulnerable to attacks from both snakes and birds of prey. Aye-aye are solitary animals that mark their large home range with scent. The well adapted aye-aye is the only primate to use echolocation to find its prey. The aye-aye is a weird and wonderful creature that can only be found on the island of Madagascar. Giant, sensitive ears help the animal detect prey. In one study, the height of such nests in trees was found to average 17.6 m (57.74 ft). It builds several nests of twigs and leaves on its territory and it often changes its location to escape from the predators. [32] The aye-aye begins foraging between 30 minutes before and three hours after sunset. Initially, Geoffroy considered using the Greek name Scolecophagus ("worm-eater") in reference to its eating habits, but he decided against it because he was uncertain about the aye-aye's habits and whether other related species might eventually be discovered. Big, yellow eyes let it see in the dark. The species has an average head and body length of 36–43 cm (14–17 in) plus a tail of 56–61 cm (22–24 in), and weighs around 2 kilograms (4 pounds).[5]. The ears of the aye-aye are extremely large and moveable, to assist in locating larvae in wood cavities through a hunting technique known as percussive foraging. Aye Ayes feed on wood boring larvae, seeds, fruit, fungi and nectar. The aye aye can only be found on the island of Madagascar. Colin Groves upheld this classification in 2005 because he was not entirely convinced the aye-aye formed a clade with the rest of the Malagasy lemurs. The aye aye does not make a good pet, as this primate is not domesticated. Aye-ayes utilize an acoustic feedback system by tapping on wood surfaces to listen for cavities in trees that house potential prey Aye-ayes break through natural material by gnawing, then retrieve prey using their long, thin fingers Role of Enrichment: Fish & Wildlife Service Species Profile, https://en.wikipedia.org/w/index.php?title=Aye-aye&oldid=994327954, Wikipedia articles needing page number citations from December 2020, Short description is different from Wikidata, Articles with unsourced statements from April 2011, Srpskohrvatski / српскохрватски, Creative Commons Attribution-ShareAlike License, This page was last edited on 15 December 2020, at 03:51. The hands of the aye aye are the most distinctive characteristic, next to the eyes, as they feature long, thin fingers with claw-like nails. [16] In 1931, Anthony and Coupin classified the aye-aye under infraorder Chiromyiformes, a sister group to the other strepsirrhines. Although they are known to come down to the ground on occasion, aye-ayes sleep, eat, travel and mate in the trees and are most commonly found close to the canopy where there is plenty of cover from the dense foliage. The aye aye may not look like a primate, but this rare animal is actually related to apes. However, the aye-aye is also similar to felines in its head shape, eyes, ears and nostrils. The home ranges of males often overlap, and the males can be very social with each other. [8] From an ecological point of view, the aye-aye fills the niche of a woodpecker, as it is capable of penetrating wood to extract the invertebrates within. The Aye-aye is not just nocturnal, but it is also arboreal. Another hypothesis proposed by Simons and Meyers (2001) is that it derives from "heh heh", which is Malagasy for "I don't know". Male aye-ayes are very assertive in this way, and sometimes even pull other males away from a female during mating. This foraging method is called percussive foraging, and takes up 5–41% of foraging time. CTRL + SPACE for auto-complete. Many of these villagers are very poor and they cling to the legends of the past. They are not typically monogamous, and will often challenge each other for mates. [33], The aye-aye was thought to be extinct in 1933, but was rediscovered in 1957. The smaller territories of females often overlap those of at least a couple of males. This includes caterpillars, tadpoles, maggots, grubs, and nymphs. [38] Recent research shows the aye-aye is more widespread than was previously thought, but its conservation status was changed to Endangered in 2014. In addition, the native population has engaged in killing the animal on sight due to superstitious beliefs. It has been considered a highly derived member of the family Indridae, a basal branch of the strepsirrhine suborder, and of indeterminate relation to all living primates. The possession of continually growing incisors (front teeth) parallels those of rodents, leading early naturalists to mistakenly classify the aye-aye within the mammalian order Rodentia[14] and as a squirrel, due to its toes, hair coloring, and tail. - Wildlife Journal Junior [27] In 2008, Russell Mittermeier, Colin Groves, and others ignored addressing higher-level taxonomy by defining lemurs as monophyletic and containing five living families, including Daubentoniidae. Diet:The aye-aye’s diet is highly specialized, consisting mainly of the interior of Ramy nuts, nectar from the Traveller’s Palm tree, some fungi and insect grubs. The Aye-ayes are the only primates thought to use echolocation to find prey. They just use their fingers to do it. Most of these primates are furry, cuddly-looking creatures, except one: the aye-aye. [6][7] The only other animal species known to find food in this way is the striped possum. If correct, then the name might have originated from Malagasy people saying "heh heh" to avoid saying the name of a feared, magical animal. However, little is known about predation on aye-ayes. Aye-aye spends a day in nests in the trees. Horizontal movement is more difficult, but the aye-aye rarely descends to jump to another tree, and can often travel up to 4 km (2 1⁄2 mi) a night. The nest has a single hole for going in and out. [16][18][19][20][21][22][23][24] The most parsimonious explanation for this is that all lemurs are derived from a single ancestor that rafted from Africa to Madagascar during the Paleogene. Prey Most of the time, the Aye-Aye Lemurs mainly eat insects and grubs. Among the aye-aye's signature traits are its fingers. The aye aye does not have a breeding season, but mates whenever the female advertises that she is ready by emitting a distinct mating call. The aye-aye is an omnivore and commonly eats seeds, fruits, nectar and fungi, but also insect larvae and honey. [37], Like many other prosimians, the female aye-aye is dominant to the male. The aye aye is a rather solitary creature whose only main time of interaction is at the time of mating. This could be bad to habitat of the aye-ayes because lemurs are a huge part in keeping the rainforest alive. The female aye-aye gives birth to a single baby. The animals are also known to raid coconut plantations, and have been … I… The Aye-Aye is one of only two animal species that hunt for food using ‘persuasive foraging’ – a method of tapping and creating trees to find prey. Aye-ayes are well equipped to hunt one of their preferred prey – insect grub. The aye ayes favorite food source is wood-boring insect larvae, but has also been known to feast on other insect grubs, fungi, ramy nuts, palm tree nectar, coconut flesh, and other fruits when insect larvae cannot be found. The tag itself is flanked by a swallow and an octopus, and is inlaid with a shimmering blue Lapis stone, representing the vast expanse of … [9], The conservation of this species has been aided by captive breeding, primarily at the Duke Lemur Center in Durham, North Carolina. [35], The aye-aye is classically considered 'solitary' as they have not been observed to groom each other. The aye-aye commonly eats animal matter, nuts, insect larva, fruits, nectar, seeds, and fungi, classifying it as an omnivore. They tap on trees with their long middle finger and listen for wood-boring insect larvae moving under the bark. Aye-ayes were originally classified as rodents because of their continuously growing incisor teeth. The Aye Aye commonly eats animal matter, nuts, insect larvae, fruits, nectar, seeds, and fungi, classifying it as an omnivore. Adaptations for nocturnal life include dark fur that helps camouflage them in the dense forest and large ears that help them This hunting technique makes Aye-ae the only known primate to enclose his prey: hence it has extraordinarily sensitive, bats-like ears. But they’ve also caused confusion. Aye-aye nests are typically oval-shaped and placed quite high in the crowns of, forks of and tangles in trees. And a long, bushy tail allows the aye-aye to balance as it scampers along tree branches. According to Dunkel et al. The aye-aye (Daubentonia madagascariensis) is a long-fingered lemur, a strepsirrhine primate native to Madagascar with rodent-like teeth that perpetually grow[4] and a special thin middle finger. It climbs trees by making successive vertical leaps, much like a squirrel. This highly unusual animal is the largest known nocturnal primate in the world, and possesses interesting characteristics that set the mammal apart from all the rest. The aye aye is believed by the native people of Madagascar to be a bad omen. Outside of mating, males and females interact only occasionally, usually while foraging. Aye-ayes live alone or in pairs. They tap on trees with their long middle finger and listen for wood-boring insect larvae moving under the bark. This hunting technique makes the aye-aye the only known primate to echolocate its prey: hence its extraordinarily sensitive, bat-like ears. Aye aye is the key to Stephen King’s pennywise interruption, at least according to the local Malagasy legend. Read on to learn more about the aye aye. [17], However, molecular results have consistently placed Daubentonia as the most basal of lemurs. The aye aye is cared for in breeding colonies and national parks by imitating the natural habitat of this unique creature. The aye aye is a nocturnal creature, meaning it sleeps during the day, and, when they are awake, they spend the night feeding. Their incisors also are used to pry open the hard shells of coconuts or hard fruits and nuts. The aye-aye is a nocturnal and arboreal animal meaning that it spends most of its life high in the trees. (adsbygoogle = window.adsbygoogle || []).push({}); Animals.NET aim to promote interest in nature and animals among children, as well as raise their awareness in conservation and environmental protection. Aye-ayes tap on the trunks and branches of trees at a rate of up to eight times per second, and listen to the echo produced to find hollow chambers. The aye aye has a unique way to find its food, using a technique called “echolocation,” which is the act of producing sound waves to find prey. Aye-ayes may be prey for fossas, Cryptoprocta ferox, one of Madagascar’s largest carnivores. Aye-ayes are sometimes suggested to parallel the niche of birds like woodpeckers in the way they seek out prey under the bark and then dig them out. It is currently classified as Endangered by the IUCN; and a second species, Daubentonia robusta, appears to have become extinct at some point within the last 1000 years. Females have two nipples located in the region of the groin. The gestation period, which is the period of time the female carries the baby in her uterus, lasts approximately 160-170 days (about 5 1/2 months), before giving birth to a single baby aye aye. IT'S ALL RELATIVE The aye-aye’s odd traits may be useful to the animal. Captive breeding colonies of the aye aye can be found in the London zoo, the Durrell Wildlife Conservation Trust in Jersey (in the Channel Islands), and at the Duke Primate Centre in North Carolina. They are the only primates thought to use echolocation to find prey. The aye-aye is a nocturnal and arboreal animal meaning that it spends most of its life high in the trees. [36] Regular scent marking with their cheeks and neck is how aye-ayes let others know of their presence and repel intruders from their territory. The aye-aye is to lemurs what Stephen King’s Pennywise is to clowns, at least according to local Malagasy legend. The Aye-Aye’s middle finger really does have a long pointed, crooked, creepy looking digit. [9][10], The aye-aye is the only extant member of the genus Daubentonia and family Daubentoniidae. [13], The French naturalist Pierre Sonnerat was the first to use the vernacular name "aye-aye" in 1782 when he described and illustrated the lemur, though it was also called the "long-fingered lemur" by English zoologist George Shaw in 1800—a name that did not stick. Males are normally locked to females during mating in sessions that may last up to an hour. [12], Due to its derived morphological features, the classification of the aye-aye was debated following its discovery. The aye aye is a bizarre primate that was originally classified as a rodent. The aye aye makes a nest out of the branches and leaves, which looks like a ball up in the crown of tall forest trees. Creatures of the Night Aye-ayes are nocturnal spending up to 80% of the nighttime hours foraging for food. [39], As many as 50 aye-ayes can be found in zoological facilities worldwide. The Aye-Aye uses this middle finger to scoop out the pulp of coconuts and mangos. Although endemic (only found in one geographical area) to this country, the species is wide-ranging, being seen from the rainforests of Madascar’s east coast, to the dry forests of the northwest. The Aye-Aye will tap into the trees 8 times per second and tap and draw between 5 and 41 percent of its disturbing time to create a hole for its prey. During the day, aye-ayes sleep in spherical nests in the forks of tree branches that are constructed out of leaves, branches and vines before emerging after dark to begin their hunt for food. Specifically, they were responsible for the first aye-aye born into captivity and studied how he and the other aye-aye infants born at the center develop through infancy. [31] They sleep during the day in nests built from interwoven twigs and dead leaves up in the canopy among the vines and branches. The Aye-Aye Lemur is also part of legends and superstitions in many of these villages. The male aye aye has a territory of approximately 240-494 acres (100-200 hectares ), which he marks by rubbing his rump, face, and neck onto various branches, to keep other males away. Each home range occupied by a single male aye aye is home to several female aye aye. [15], A full-grown aye-aye is typically about 90 centimetres (3 feet) long with a tail longer than its body. [28], Further evidence indicating that the aye-aye belongs in the superfamily Lemuroidea can be inferred from the presence of petrosal bullae encasing the ossicles of the ear. [20][25][26] Similarities in dentition between aye-ayes and several African primate fossils (Plesiopithecus and Propotto) have led to the alternate theory that the ancestors of aye-ayes colonized Madagascar separately from other lemurs. The Australian ghost shark has an elephant-like snout that detects prey … An Aye-Aye Image courtesy of Frank Vassen/Flickr This method of finding food is called percussive foraging and is also used by woodpeckers. [29] The aye-aye has also evolved a sixth digit, a pseudothumb, to aid in gripping.[30]. Unfortunately, this weird appearance has led some local on Madagascar to fear or hate them as bad omens–killing them on sight to ward off spirits. [33] The aye-aye is thought to be the only primate which uses echolocation to find its prey. The aye aye’s favorite food source is wood-boring insect larvae, but has also been known to feast on other insect grubs, fungi, ramy nuts, palm tree nectar, coconut flesh, and other fruits when insect larvae cannot be found. Researchers believe that after the female aye aye mates, she will not give birth again for almost three years. They feel that this Lemur is a form of evil and that it should be killed immediately. Males are known to cover distances of up to 4km a night in their search for food, feeding on a … The Sakalava people go so far as to claim aye-ayes sneak into houses through the thatched roofs and murder the sleeping occupants by using their middle finger to puncture the victim's aorta. It is for this reason that they are readily killed. [12] In 1863, British zoologist John Edward Gray coined the family name Daubentoniidae. When insects and grubs are nowhere to be seen, they will feast on fungi, fruit, and nuts. A captive temperature of 63º – 82º F (17º – 28º C) is maintained to mimic the seasonal temperatures of Madagascar. For the nautical phrase, see, "Daubentonia" redirects here. Besides humans, main predators of aye-aye are fossa and birds of prey. Aye-ayes are endangered in Madagascar. The third finger is so thin, that it looks more like bone than a finger, but its special design helps the aye aye dig out insect larvae, and the meat of coconuts. Diet. The secretive and tree-dwelling lifestyle of the Aye Aye means that it actually has very few natural predators in its native environment, with the agile and equally nocturnal Fossa being their most ferocious natural predator (along with Birds of Prey and Snakes that hunt the smaller and more vulnerable young). According to Sonnerat, the name "aye-aye" was a "cri d'exclamation & d'étonnement" (cry of exclamation and astonishment). They use this finger to tap, tap, and tap on tree branches and logs to hear if there is a hollow area beneath the bark to pull out and eat the grubs that lie underneath. [6] Once a chamber is found, they chew a hole into the wood and get grubs out of that hole with their highly adapted narrow and bony middle fingers.
