Each home range occupied by a single male aye aye is home to several female aye aye. 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. It climbs trees by making successive vertical leaps, much like a squirrel. When insects and grubs are nowhere to be seen, they will feast on fungi, fruit, and nuts. The Aye-Aye Lemur is also part of legends and superstitions in many of these villages. Aye-aye and lemurs - when the aye-aye is in hiding, the main prey of the fossa is lemurs. [11], The genus Daubentonia was named after the French naturalist Louis-Jean-Marie Daubenton by his student, Étienne Geoffroy Saint-Hilaire, in 1795. [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. They are seen exhibiting polygyny because of this. The Aye-Aye uses this middle finger to scoop out the pulp of coconuts and mangos. Aye Ayes feed on wood boring larvae, seeds, fruit, fungi and nectar. [citation needed] However, recent research suggests that it is more social than once thought. Like many lemurs, the aye-aye is rated ‘ Endangered ‘ by the IUCN. 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. [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. [9][10], The aye-aye is the only extant member of the genus Daubentonia and family Daubentoniidae. The aye aye is exclusively found on the island of Madagascar, spending its whole life in the very tops of the rain forest trees. The Australian ghost shark has an elephant-like snout that detects prey … [15], A full-grown aye-aye is typically about 90 centimetres (3 feet) long with a tail longer than its body. The aye aye can only be found on the island of Madagascar. It is difficult for the males to defend a singular female because of the large home range. [6][7] The only other animal species known to find food in this way is the striped possum. Diet. The aye-aye is an omnivore and commonly eats seeds, fruits, nectar and fungi, but also insect larvae and honey. 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. 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. IT'S ALL RELATIVE The aye-aye’s odd traits may be useful to the animal. 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. 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 complex geometry of ridges on the inner surface of aye-aye ears helps to sharply focus not only echolocation signals from the tapping of its finger, but also to passively listen for any other sound produced by the prey. 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. 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. Its natural habitat is rainforest or deciduous forest, but many live in cultivated areas due to deforestation. 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. [31] The aye aye’s middle finger is extremely thin, to the point that it looks no larger than the bone underneath. I… [5], The aye-aye lives primarily on the east coast of Madagascar. Its teeth are efficient tools for gaining access to the meat of coconuts, while the long middle finger is … The Aye-ayes are the only primates thought to use echolocation to find prey. Another hypothesis proposed by Simons and Meyers (2001) is that it derives from "heh heh", which is Malagasy for "I don't know". The well adapted aye-aye is the only primate to use echolocation to find its prey. Aye-aye nests are typically oval-shaped and placed quite high in the crowns of, forks of and tangles in trees. Prey Most of the time, the Aye-Aye Lemurs mainly eat insects and grubs. The Aye-Aye’s middle finger really does have a long pointed, crooked, creepy looking digit. Many of these villagers are very poor and they cling to the legends of the past. Rainforest aye-ayes, the most common, dwell in canopy areas, and are usually sighted above 70 meters altitude. [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. [16] In 1931, Anthony and Coupin classified the aye-aye under infraorder Chiromyiformes, a sister group to the other strepsirrhines. 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. Lemurs exist only on the island of Madagascar. Besides humans, main predators of aye-aye are fossa and birds of prey. The aye aye is believed by the native people of Madagascar to be a bad omen. (2012), the widespread use of the Malagasy name indicates that the name could not have come from Sonnerat. Their incisors also are used to pry open the hard shells of coconuts or hard fruits and nuts. An aye-aye clings to a palm in eastern Madagascar. This includes caterpillars, tadpoles, maggots, grubs, and nymphs. 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). 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. (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. They then employ the same middle finger to fish them out. 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. They are the only primates thought to use echolocation to find prey. Young aye-ayes typically are silver colored on their front and have a stripe down their back. The aye aye is a highly unusual primate that was originally classified as a rodent, until further research was done on this bizarre creature. Aye-ayes are well equipped to hunt one of their preferred prey – insect grub. They are not typically monogamous, and will often challenge each other for mates.
