The Family Daubentoniidae consists of a single living species, the aye-aye (Daubentonia madagascariensis), a unique primate native to Madagascar. Aye-ayes are nocturnal and arboreal, with distinctive features including large, continuously growing incisors and an elongated, thin middle finger used to tap on wood and extract insect larvae—a foraging method known as percussive foraging. They have large eyes adapted for night vision, a bushy tail, and highly specialized hands for manipulating food. As the sole representative of their family, aye-ayes are considered evolutionarily distinct, playing an important ecological role as insect predators and seed dispersers, though they are threatened by habitat loss and local superstition.
