ayeaye

The aye-aye (Daubentonia madagascariensis) is a nocturnal lemur native to Madagascar and the sole extant species in the family Daubentoniidae. It is a medium-sized primate with a sparse fur coat, large ears, and a distinctive elongated middle finger used for extracting insect larvae from wood. Its incisors grow continuously and are used to gnaw holes in wood to reach food.

Foraging and diet: The aye-aye employs percussive foraging, tapping on tree trunks to locate hollow sounds that indicate larvae. After gnawing a small hole with its incisors, it probes the opening with its long finger to pull out larvae. Its diet includes insect larvae, fruit, nectar, seeds, and fungi.

Behavior and ecology: It is arboreal and largely solitary, though a mother with an offspring may be accompanied by one or more young. Activity is primarily at night, and individuals have relatively large home ranges that depend on forest structure and food availability. The aye-aye is adapted to a variety of forest types but remains closely tied to wooded habitats.

Reproduction and life history: Breeding can occur year-round in some regions. Gestation lasts about five months, typically yielding a single infant, which is carried by the mother for several months before weaning.

Distribution and habitat: Endemic to Madagascar, the aye-aye occurs across several forested regions of the island, from humid to drier forests. It is highly affected by deforestation and habitat fragmentation, which reduce available foraging and nesting sites.

Conservation status: The aye-aye is listed as Endangered on the IUCN Red List. Primary threats include habitat loss, fragmentation, and human persecution driven by folklore. Conservation efforts focus on protected areas, habitat restoration, and community-based programs to safeguard remaining populations.
