Aye-Aye Classification & Evolution

The Aye Aye lemur is a species of lemur that lives in Madagascar's rainforests. The Aye Aye lemur is not only the world's largest nocturnal primate, but also one of the most unusual. In fact, when it was first discovered, it was thought to be a large species of Squirrel. The Aye Aye lemur was finally recognised as a species of Lemur in the mid 1800s, but it was classified in a group of its own because their closest Lemur relatives remain a mystery even today.

However, these incredibly unique animals are severely threatened throughout much of their natural habitat and were thought to be on the verge of extinction by 1980, owing primarily to them being killed instantly by locals who believe that seeing an Aye Aye lemur is a sign of bad luck. Despite the fact that population numbers appear to be increasing, the Aye Aye lemur is one of Madagascar's most endangered animal species.

Aye-Aye Lemur Anatomy and Appearance

The Aye Aye is a primate that is most closely related to Lemurs but is one of the most unique animals on the planet due to a variety of very distinct adaptations. Their body and long tail are covered in coarse, shaggy black or dark brown fur with a layer of white guard hairs that help them blend into the surrounding forest at night. The Aye Aye has large eyes on its pointed face, a pink nose, and rodent-like teeth with incisors that grow continuously to avoid becoming blunt.


Their large rounded ears are extremely sensitive, providing the Aye Aye with excellent hearing when listening for grubs beneath the tree bark, and they can rotate independently. The Aye Aye has long as well as bony fingers with sharp pointed claws on the ends to aid in dangling from branches, but their most distinguishing feature is the middle fingers on their front feet. These opposable fingers, which are much longer than the others and have a double-jointed tip and a hooked claw on the end, are used for both detecting and extracting grubs in dead wood.

Aye -Aye Animal

Aye-ayes can be easily found on the island of Madagascar. Although these strange creatures do not appear to be primates at first glance, they are related to chimps, apes, and humans.


Aye-aye (Daubentonia madagascariensis), the only living member of the Daubentoniidae family and a rare squirrel-like primate of Madagascar. The majority of aye-ayes are nocturnal, solitary, and arboreal, and they live in the eastern Madagascar rainforests. However, fossils from Egypt and Kenya dating back 34 million years suggest that modern aye-ayes evolved in Africa before spreading to Madagascar. The aye-aye is distinguished by its unusually long third digit.


The aye-aye is about 40 cm (that is equal to 16 inches) long, excluding the bushy tail that measures 55 to 60 cm (21.6 to 23.6 inches). It has a short face, large eyes, and rodent-like incisors that are covered in long, coarse, dark brown or black fur.


The hands of the aye-aye are large, and its fingers, particularly the third, are long and slender. The species has five fingers on each hand and a pseudo-thumb, a distinct bony digit found in no other primate. Except for the large opposable flat-nailed great toes, all of the fingers and toes have pointed claws. The aye-aye builds a large ball-shaped nest of leaves in forked tree branches and feeds primarily on insects and fruit. It finds wood-boring insect larvae by tapping the tree with its long, specialised third finger, apparently listening for the hollow sound of the channels the grubs make through the wood, and then extracts the insects with this finger.It also digs the pulp out of fruit with the third finger. The female gives birth to a single child.

Coloring and Anatomy

Aye-ayes have a bushy tail that is longer than their body and are dark brown or black in colour. They also have large, sensitive ears, large eyes, and thin fingers. Aye-ayes have pointed claws on all of their fingers and toes, with the exception of their opposable big toes, which allow them to dangle from branches.

Life in the Canopy

Aye-ayes spend their lives in rainforest trees, avoiding human contact. They sleep at night and spend the day curled up in a ball of leaves and branches. The nests, which look like closed spheres with a single entry hole, are found in the forks of large trees.


While perched in the air, the aye-aye taps on trees with its long middle finger, listening for wood-boring insect larvae moving beneath the bark. It extracts them with the same middle finger. The digit can also be used to scoop the flesh from coconuts as well as other fruits, supplementing the animal's insect diet.

Superstitions of Aye-Aye Animal

Many Malagasy people consider the aye-aye to be a bad omen. As a result, they are frequently executed on the spot. Aye-aye populations are in jeopardy as a result of such hunting and habitat destruction. They are now legally safeguarded.

Aye-Aye Habitat and Distribution 

Historically, the Aye Aye was a species that lived in the coastal forests of eastern and northwestern Madagascar, but by 1983, they were thought to be nearly extinct, with only a few scattered individuals remaining. Since then, their population has grown, and while these populations aren't particularly large, they can now be found in an increasing number of locations and in a variety of different forest habitats.

The Aye Aye prefers dense tropical and coastal rainforest with plenty of cover, but they have also been observed in secondary forest, bamboo thickets, mangroves, and even coconut groves along Madagascar's eastern coast. However, in addition to being persecuted by locals, the Aye Aye are severely threatened in their natural environment due to habitat loss.

Aye-Aye Behaviour and Lifestyle

The Aye Aye is a nocturnal and arboreal animal, which means it spends the majority of its time in the trees. Aye Ayes sleep, eat, travel, as well as mate in the trees as well as are most commonly found close to the canopy where there is plenty of cover from the dense foliage.

Aye Ayes spend the day sleeping in spherical nests made of leaves, branches, and vines in the forks of tree branches before emerging after dark to begin their hunt for food. The Aye Aye lemur is a solitary animal that uses scent to mark its large home range, with a female's smaller territory frequently overlapping those of at least a couple of males. Male Aye Ayes tend to share territories with other males and have even been known to share the same nests (though not at the same time), and they can appear to tolerate each other until they hear the call of a female looking for a mate.

Aye-Aye Reproduction & Life Cycles

Previously, it was thought that the Aye Aye had a very strict breeding season (similar to other Lemurs), but they actually seem to breed all year, depending on when the female comes into season. When a female is ready to mate, she calls to male Lemurs, who are known to congregate around her and fight aggressively for breeding rights.


After a five-month gestation period, a single infant is born and spends the first two months in the safety of the nest, not being weaned until it is at least seven months old. Young Aye Ayes will stay with their mother until they are two years old, at which point they will leave to establish their own territory. Female Aye Aye are thought to be able to reproduce when they are between the age of 3 and 3.5 years old, whereas males appear to be able to reproduce at least 6 months earlier.

Aye-Aye Diet and Prey

The Aye Aye is an omnivorous animal that feeds on both other animals and plant matter while moving through the trees at night. Males have been observed travelling up to 4km per night in search of food, feeding on a variety of fruits, seeds, insects, and nectar.


They are, however, uniquely adapted to hunt by tapping dead wood with their elongated middle finger in search of the hollow tunnels created by wood-boring grubs, listening for even the slightest sound with their sensitive bat-like ears.


When the Aye Aye detects its prey, it uses its sharp front teeth to gnaw a hole in the wood before inserting its long middle finger, hooking the grub with its claw, as well as extracting it (filling the same ecological niche as a Woodpecker). The Aye Aye is also known to use this long digit to eat eggs and coconut flesh, and it is thought to be the only primate that uses echolocation to find food.

Aye-Aye Predators and Threats

Because of the Aye Aye's secretive as well as tree-dwelling lifestyle, it 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 as well as Snakes that hunt the smaller and more vulnerable young). Humans are the greatest threat to the Aye Aye, as populations have been wiped out in much of their native forests due to superstition among locals who believe that seeing one is a bad omen.


In other areas where they are not so feared, the Aye Aye is hunted for bushmeat. The greatest threat to current populations, however, is habitat loss caused by both deforestation and expanding human settlements that encroach on the Aye Aye's natural habitat.

FAQs (Frequently Asked Questions)

Question 1) What is Aye-Aye Size?

Answer) Length: 40 cm (Adult) and mass of 2.3 kg (Adult).

Question 2) Can Aye Aye Kill You? How Long Do Aye Ayes Live?

Answer) Although the aye-aye weighs only 4 pounds in the wild, locals in Madagascar, the only place on Earth where these creatures can be found, regard this tiny animal as a forerunner of death. However, because of the aye-perception, this perfectly harmless creature is frequently killed on sight.


At over 9 inches long, the aye-tail aye's hairs are the longest of any prosimian (a group that includes lorises, bush babies, lemurs, and tarsiers). In captivity, aye-ayes can live for more than 20 years.

Question 3) What are Aye Aye Babies Called? Can You Have an Aye Aye Lemur as a Pet?

Answer) If you go to Madagascar, you might just see one of these. He is an aye aye (pronounced eye eye), and he can only be found on a small island off the southeastern coast of Africa. Aye ayes are members of the lemur family, and baby aye ayes are referred to as "infants," just like you!


The Aye Aye belongs to the Lemur family. It is a nocturnal primate from Madagascar. It uses its long, thin middle finger to tap on trees in search of grubs. Because of their scarcity, the Aye Aye is unlikely to be legal to keep as a pet.
