What is an Aye-Aye?

Sheri Cyprus

An aye-aye is a very unusual-looking lemur native to Madagascar. Some aye-ayes are kept in a few zoos around the world, but they are very rare. The aye-aye is often considered grotesque as it has a very pointed face with veined skin, gigantic yellow-green staring bulbous eyes, huge bat-like ears, odd-looking disproportionate legs and toes and a coarse, scruffy coat.

Traditionally, the Malagasy believe that the aye-aye is a harbinger of death. They have killed off most of the species and the aye-aye is often considered an endangered species. It doesn't help matters that ayes-ayes are known to steal eggs and other foods quite brazenly from the villagers, much like raccoons are known to do in other parts of the world. The aye-aye's natural habitats are shrinking as the rainforests decline.

The aye-aye lives in trees in the rainforest and in other areas on Madagascar's eastern coast. As they dwell in the canopies of trees, they often find and eat fruit there, but aye-ayes are omnivores meaning that they eat just about any type of food. Their long toes, with the middle one being the longest, allow them to dig out insects from inside branches. Aye-ayes also have rodent-like teeth for ripping off tree bark to find grubs for food.

The aye-aye is nocturnal and sleeps in its tree nest during the day. Although the aye-aye has rodent-like teeth and a squirrel-like tail, it is a primate. The aye-aye is a member of the lemur family and lemurs, like humans, monkeys and apes, are primates. Yet the aye-aye is different from other lemurs because of its unusual feet and other characteristics and is considered a rare type of lemur.

Only a handful of zoos and zoological centers around the world have aye-ayes. Madagascar's Tsimbazaza Zoo has them as does the Ueno Zoo in Tokyo. As aye-ayes are so rare, zoos began an international cooperation program that focuses on the breeding of aye-ayes. The United Kingdom (UK) has had aye-ayes in three zoos: The Jersey Zoo, The London Zoo and the Bristol Zoo. In the United States, Duke University's Duke Lemur Center in Durham, North Carolina has aye-ayes. The public can usually see the aye-ayes there, but it is strictly by appointment only.

Frequently Asked Questions

What is an Aye-Aye and where can it be found?

An Aye-Aye is a unique species of lemur found only in Madagascar. It's known for its distinctive features, such as large eyes, elongated middle finger, and bushy tail. These nocturnal creatures inhabit rainforests and are adept at foraging for food in the trees, playing a crucial role in the ecosystem as a seed disperser and predator of wood-boring insect larvae.

Why does the Aye-Aye have such an unusual appearance?

The Aye-Aye's peculiar look, including its rodent-like teeth and extended middle finger, is an adaptation to its specialized diet. Its ever-growing incisors allow it to gnaw through wood, while the slender finger is used to extract grubs from tree bark. This unique combination of features makes the Aye-Aye a master at finding and extracting its prey.

Is the Aye-Aye endangered?

Yes, the Aye-Aye is classified as Endangered by the International Union for Conservation of Nature (IUCN). Habitat destruction due to logging and agriculture, along with hunting by locals who consider it an omen of bad luck, has led to a decline in its population. Conservation efforts are crucial to ensure the survival of this distinctive species.

What do Aye-Ayes eat?

Aye-Ayes have a varied diet that primarily consists of insects, nectar, fruit, and seeds. Their most notable feeding behavior involves tapping on wood to locate insect larvae, then using their elongated middle finger to fish them out. This method, known as percussive foraging, showcases the Aye-Aye's ecological niche as a nocturnal hunter.

How do Aye-Ayes communicate with each other?

Aye-Ayes communicate through a range of vocalizations, body postures, and facial expressions. They are generally solitary animals but may use calls to establish territory or attract mates. Researchers have documented various vocal sounds, including screams, grunts, and mewing noises, which convey different messages or states of arousal.

What conservation efforts are in place to protect the Aye-Aye?

Conservation efforts for the Aye-Aye include habitat protection, captive breeding programs, and local education initiatives to reduce superstitions that lead to their killing. Organizations like the Madagascar Fauna and Flora Group work to preserve the Aye-Aye's natural habitat, while zoos around the world participate in breeding programs to maintain genetic diversity.
