The aye aye’s middle finger is extremely thin, to the point that it looks no larger than the bone underneath. If correct, then the name might have originated from Malagasy people saying "heh heh" to avoid saying the name of a feared, magical animal. The aye-aye also eats nectar, seeds, and fruit. Aye-ayes are well equipped to hunt one of their preferred prey – insect grub. [32], This article is about the lemur species. But they’ve also caused confusion. IT'S ALL RELATIVE The aye-aye’s odd traits may be useful to the animal. 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. In addition, the native population has engaged in killing the animal on sight due to superstitious beliefs. The Aye-Aye Lemur is also part of legends and superstitions in many of these villages. [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 tag itself is flanked by a swallow and an octopus, and is inlaid with a shimmering blue Lapis stone, representing the vast expanse of … However, little is known about predation on aye-ayes. 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. And a long, bushy tail allows the aye-aye to balance as it scampers along tree branches. 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. An aye-aye clings to a palm in eastern Madagascar. A captive temperature of 63º – 82º F (17º – 28º C) is maintained to mimic the seasonal temperatures of Madagascar. According to Sonnerat, the name "aye-aye" was a "cri d'exclamation & d'étonnement" (cry of exclamation and astonishment). Some say that the appearance of an aye-aye in a village predicts the death of a villager, and the only way to prevent this is to kill it. Male aye-ayes tend to share their territories with other males and are even known to share the same nests (although not at the same time), and can seemingly tolerate each other until they hear the call of a female that is looking for a mate. For the defunct legume genus, see, "Revision of the Species of Lemuroid Animals, with the Description of some New Species", "Giant rabbits, marmosets, and British comedies: etymology of lemur names, part 1", "Primate jumping genes elucidate strepsirrhine phylogeny", "Development and application of a phylogenomic toolkit: Resolving the evolutionary history of Madagascar's lemurs", "DNA from extinct giant lemurs links archaeolemurids to extant indriids", "A Molecular Phylogeny of Living Primates", "A Genome Sequence Resource for the Aye-Aye (, "Fossil lemurs from Egypt and Kenya suggest an African origin for Madagascar's aye-aye", "Anatomy of the hand and arm in Daubentonia madagascariensis: a functional and phylogenetic outlook", "Primate Factsheets: Aye-aye (Daubentonia madagascariensis) Behavior", "Was the Oligo-Miocene Australian metatherian, "Molecular evolutionary dynamics of cytochrome, U.S. 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. [9], The conservation of this species has been aided by captive breeding, primarily at the Duke Lemur Center in Durham, North Carolina. 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 animals are also known to raid coconut plantations, and have been … [9][10], The aye-aye is the only extant member of the genus Daubentonia and family Daubentoniidae. However, American paleoanthropologist Ian Tattersall noted in 1982 that the name resembles the Malagasy name "hai hai" or "hay hay", which refers to the animal and is used around the island. The aye aye does this by tapping its middle finger on the bark of trees, which helps the animal to locate wood-born insect larvae tunneling through the tree. Aye-aye captain, less than cute furry creatures full steam ahead. [39], As many as 50 aye-ayes can be found in zoological facilities worldwide. 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. Outside of mating, males and females interact only occasionally, usually while foraging. The aye aye has become critically endangered, due to people hunting the creature for sport. The Aye-ayes are the only primates thought to use echolocation to find prey. 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. The infant will remain in the forest nest for two months before the primate is mature enough to venture out. This includes caterpillars, tadpoles, maggots, grubs, and nymphs. The well adapted aye-aye is the only primate to use echolocation to find its prey. The opposable big toes of the aye aye are what allows it to dangle from tree branches without falling. 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. This means that it generally spends most … The aye aye is not a domesticated creature, but does belong to a large group of captive breeding programs and protected areas. [12], Due to its derived morphological features, the classification of the aye-aye was debated following its discovery. Others believe, if one points its narrowest finger at someone, they are marked for death. 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. Aye-ayes are endangered in Madagascar. It is the world's largest nocturnal primate. Aye-aye spends a day in nests in the trees. Protected areas that are home to a large population of the aye aye species include Madagascar’s Nosy Mangabe Special Reserve, Andasible-Mantadia National Park, Ranomafana National Park, and Ankarana Reserve. [33][34], Though foraging is usually solitary, they occasionally forage in groups. The aye aye is a highly unusual primate that was originally classified as a rodent, until further research was done on this bizarre creature. [1][2] This is for three main reasons: the aye-aye is considered evil, the forests of Madagascar are being destroyed, and the farmers will kill aye-ayes to protect their crops and for poaching. 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. An Aye-aye's prey are insect larva. The aye aye is believed by the native people of Madagascar to be a bad omen. Females have two nipples located in the region of the groin. Big, yellow eyes let it see in the dark. On the head and back, the ends of the hair are typically tipped with white while the rest of the body will ordinarily be a yellow and/or brown color. [40], The aye-aye is often viewed as a harbinger of evil and killed on sight. Another hypothesis proposed by Simons and Meyers (2001) is that it derives from "heh heh", which is Malagasy for "I don't know". Aye-ayes are particularly fond of ceramicist beetles. This hunting technique makes Aye-ae the only known primate to enclose his prey: hence it has extraordinarily sensitive, bats-like ears. 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. 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. Prey Most of the time, the Aye-Aye Lemurs mainly eat insects and grubs. [5] It is characterized by its unusual method of finding food: it taps on trees to find grubs, then gnaws holes in the wood using its forward-slanting incisors to create a small hole in which it inserts its narrow middle finger to pull the grubs out. [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. The aye-aye is a nocturnal and arboreal animal meaning that it spends most of its life high in the trees. Read on to learn more about the aye aye. Humans have also destroyed a great portion of the aye aye’s natural habitat, cutting down the forest trees to make way for agricultural development. [31] Each home range occupied by a single male aye aye is home to several female aye aye. Humans are in fact the biggest threat to the Aye Aye as populations have been obliterated in much of their native forests due to superstition from local people who believe that it is a bad omen to see one. This nautical charm pendant is inspired by military dog tags, and is named after the response given to a command from a ranking officer. [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. This method of finding food is called percussive foraging and is also used by woodpeckers. The Aye-Aye uses this middle finger to scoop out the pulp of coconuts and mangos. Lemurs exist only on the island of Madagascar. 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. These ridges can be regarded as the acoustic equivalent of a Fresnel lens, and may be seen in a large variety of unrelated animals, such as lesser galago, bat-eared fox, mouse lemur, and others. CTRL + SPACE for auto-complete. [17], However, molecular results have consistently placed Daubentonia as the most basal of lemurs. [15] The skinny middle finger is unique in the animal kingdom in that it possesses a ball-and-socket metacarpophalangeal joint. Its natural habitat is rainforest or deciduous forest, but many live in cultivated areas due to deforestation. [32] The aye-aye begins foraging between 30 minutes before and three hours after sunset. 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 tap on trees with their long middle finger and listen for wood-boring insect larvae moving under the bark. The baby is weaned when it is about seven months old, but it stays with its mother for around two years. They have sent multiple teams to capture lemurs in Madagascar and have since created captive breeding groups for their lemurs. [16] In 1931, Anthony and Coupin classified the aye-aye under infraorder Chiromyiformes, a sister group to the other strepsirrhines. The aye-aye is an omnivore and commonly eats seeds, fruits, nectar and fungi, but also insect larvae and honey. Aye-aye is a solitary creature that gathers with other aye-ayes only for … Tall trees with leafy branches are also provided to allow the aye aye to create its unique, spherical nest. Researchers believe that after the female aye aye mates, she will not give birth again for almost three years. They then use their unique middle finger t… (2012), the widespread use of the Malagasy name indicates that the name could not have come from Sonnerat. [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. [24] The third finger, which is much thinner than the others, is used for tapping, while the fourth finger, the longest, is used for pulling grubs and insects out of trees, using the hooked nail. [37], Like many other prosimians, the female aye-aye is dominant to the male. Female home ranges never overlap, though a male's home range often overlaps that of several females. [11], The genus Daubentonia was named after the French naturalist Louis-Jean-Marie Daubenton by his student, Étienne Geoffroy Saint-Hilaire, in 1795. [38] Recent research shows the aye-aye is more widespread than was previously thought, but its conservation status was changed to Endangered in 2014. I… 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. Besides humans, main predators of aye-aye are fossa and birds of prey. 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. Aye-aye and lemurs - when the aye-aye is in hiding, the main prey of the fossa is lemurs. The nest has a single hole for going in and out. They use their incisors to gnaw through bark to expose insect larvae and grubs. The aye-aye is a weird and wonderful creature that can only be found on the island of Madagascar. The face of the aye aye is the lightest part of the animal, with striking, wide-open yellow-orange eyes, and big leathery ears. Adaptations for nocturnal life include dark fur that helps camouflage them in the dense forest and large ears that help them The aye aye is native to the rain forests of Madagascar, where it spends its life perched in forest trees, avoiding contact with the ground. Males are normally locked to females during mating in sessions that may last up to an hour. [33] The aye-aye is thought to be the only primate which uses echolocation to find its prey. 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. However, little is known about predation on aye-ayes. They are the only primates thought to use echolocation to find prey. However, there is no direct evidence to suggest aye-ayes pose any legitimate threat to crops and therefore are killed based on superstition. [29] The aye-aye has also evolved a sixth digit, a pseudothumb, to aid in gripping.[30]. 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. Male aye-ayes are very assertive in this way, and sometimes even pull other males away from a female during mating. The aye aye is a rather solitary creature whose only main time of interaction is at the time of mating. [15], A full-grown aye-aye is typically about 90 centimetres (3 feet) long with a tail longer than its body. They just use their fingers to do it.
