The aye-aye (Daubentonia madagascariensis) is a nocturnal lemur and strepsirrhine primate native to Madagascar. It is the only living member of the family Daubentoniidae and is known for its long middle finger, large ears, and unusual foraging behaviour.
Taxonomy and classification
The aye-aye is a lemur in the primate order and is placed in the family Daubentoniidae. It is the sole living representative of that family.
Physical characteristics
Aye-ayes have large ears, a bushy tail longer than the body, and unusually elongated fingers, especially the middle finger. Sources describe them as around 14 to 17 inches in head-and-body length, with tails up to about 24 inches.
Habitat and distribution
The species is endemic to Madagascar, where it lives in forested habitats and spends most of its life in trees. It is rarely seen on the ground.
Behaviour and diet
Aye-ayes are nocturnal and forage at night for insects, fruit, nectar, seeds, and other foods. They are especially known for tapping on wood and extracting larvae from trees.
Conservation
The aye-aye is listed as Endangered by conservation sources cited in the search results. Its survival is affected by habitat loss and other pressures on Madagascar's forests.
Key facts
- Aye-ayes are lemurs and therefore primates, not rodents.
- They are native to Madagascar and are found only there.
- They are active at night and spend much of their time in trees.
- They are known for using a long, thin middle finger to forage for insects and larvae.
- They are the sole living species in the family Daubentoniidae.
Aye-ayes are of interest to Canadian readers through zoo education, wildlife conservation, and comparative biology, especially because they are a primate species found only in Madagascar.
