Quck answer
The Aye-Aye is a unique and unusual animal found only in Madagascar. Here are 10 wild facts about this fascinating creature:
– The Aye-Aye is the world’s largest nocturnal primate.
– Aye-Ayes have long, bony fingers that they use to tap on trees to locate insects, their primary food source.
– They have a special tooth that they use to gnaw into tree bark and extract insects.
– Aye-Ayes are considered sacred by some Malagasy people, but are also feared as a symbol of death.
– They have large, reflective eyes that help them see in the dark.
– Aye-Ayes are solitary creatures and only come together to mate.
– They have a unique way of communicating using both vocalizations and tapping on objects.
– Aye-Ayes have a specially adapted middle finger that is used for grooming.
– They have a very slow reproductive rate, with females giving birth to only one offspring every 2-3 years.
– Despite being endangered due to habitat loss and hunting, the Aye-Aye has a low risk of extinction due to its adaptability and resilience.
Endangered Species

When most people hear the word “lemur,” they may immediately think of the popular ring-tailed lemur, King Julien XIII, from the movie “Madagascar.” However, there are 108 known species of lemurs (with at least 17 extinct species) in the world, and the aye-aye (pronounced “eye-eye”) stands out as the most interesting among them.
Megan McGrath, the education programs manager at the Duke Lemur Center in North Carolina, which houses the largest and most diverse population of lemurs outside of Madagascar, says that aye-ayes are her favorite primate due to their unique evolution. “Out of over 100 species of lemur, all adapting to survive on the island of Madagascar for tens of millions of years, the aye-aye somehow wound up in an incredible niche and evolved a truly unique combination of traits and behaviors found nowhere else on Earth,” she says.
The aye-aye, scientifically known as daubentonia madagascariensis, has been on Earth for millions of years and has many features that distinguish it as a lemur. However, it has more extreme morphological features than any other primate on Earth. Here are 10 intriguing facts about this unusual animal:
1. Aye-Ayes Have a Distinctive Appearance
Aye-ayes are primates, like monkeys, apes, and humans, but they resemble a mix of a raccoon and a rat. They are small, with an average length of 12 to 16 inches (30-40 centimeters) and an average weight of 5-6 pounds (2.3-2.7 kilograms). Aye-ayes have long, bushy tails (18-22 inches or 45-55 centimeters) that are larger than their bodies, and their big yellow-orange or sandy brown eyes give them a constant look of surprise. Despite their small size, they are the largest nocturnal primate in the world.

2. They Have Huge Ears
The aye-aye’s most noticeable feature is its large, triangular ears, which are the largest ears in proportion to body size of any primate. The ears are made up of ridges that allow the aye-aye to hear the slightest movements of grubs and larvae inside old, decaying trees.
3. Their Incisors Never Stop Growing
Unlike other primates, aye-ayes have continuously growing incisors, similar to rodents. This is why they were once classified as rodents. The aye-ayes use their ever-growing incisors to chew through wood, bark, nuts, and even concrete when they are bored. Their teeth continue to grow throughout their lives, so there is no need to worry if they wear down or break.
4. Their Fingers are Super Long
Aye-ayes have fingers that end with curled claws and are exceptionally long, taking up 41 percent of the total length of their forearm. They have a sixth finger on each wrist made of bone and cartilage, known as a pseudothumb, which helps them climb, grasp, and dangle from branches. When walking on the ground, aye-ayes raise their clawed fingers to protect them, which makes their gait appear clumsy.

5. Their Middle Finger is Unique
Aye-ayes have a long, thin middle finger on each front hand that can rotate 360 degrees around the joint, much like a human arm at the shoulder joint. This finger is used for percussive foraging, tapping and foraging for food. Aye-ayes are the only primates known to do this.
6. They’re Like Woodpeckers
Aye-ayes use their tapping finger to rapidly tap along a branch or trunk of a tree while positioning their sensitive ears to listen for the subtle auditory feedback that indicates grubs and larvae are inside. They use their ever-growing incisors to dig into the wood and their flexible tapping finger to hook unsuspecting bugs on their claw. Aye-ayes fill a specific ecological niche on the island of Madagascar, where there are no woodpeckers.
7. They’re Independent
Aye-ayes are introverted and prefer to spread out for foraging, reconnecting later with their group. Although they are social at times, females tend to get aggressive if another female outside her family unit comes into her area in search of food.
8. There Used to be a Giant Aye-Aye
The now-extinct Daubentonia robusta, a giant aye-aye, lived on Madagascar within the last 1,000 years. This lemur was much larger than the aye-aye and weighed up to 25 pounds.
9. They Make Strange Noises
Aye-ayes make different noises, such as screaming when aggressive, whimpering when competing for food, and making a “tiss” noise when confronted with other lemurs. They yell “hai-hai” when attempting to flee from captors, likely where their unusual name comes from.
10. They are Considered Bad Omens
Some natives of Madagascar believe aye-ayes are bad luck and that if an aye-aye points its finger at someone, they are marked for death. Others believe that aye-ayes can creep into homes and use their tapping finger to pluck out the hearts of humans.
According to McGrath, the negative reputation of aye-ayes is unwarranted. These animals are not aggressive towards their caretakers and their intelligence makes them ideal candidates for positive reinforcement training. This type of training can make veterinary care less stressful for everyone involved. However, despite their positive qualities, aye-ayes are still in danger. They are one of the most vulnerable lemur species and are on the list of the world’s 25 most endangered primates. The destruction of their natural habitat, combined with their bad reputation among locals, has contributed to their decline in numbers. Unfortunately, it is unclear how many aye-ayes remain in the wild.
