The Aye-aye (Daubentonia madagascariensis) is a nocturnal primate native to Madagascar. It has a distinctive long middle finger used for foraging insects from tree bark, large ears for acute hearing, and rodent-like incisors. It inhabits rainforest canopies and plays a crucial role in seed dispersal and pest control.

Daubentonia madagascariensis, commonly known as the aye-aye, is native to Madagascar, an island country located in the Indian Ocean off the southeastern coast of Africa. The species is endemic to this region, meaning it is not naturally found anywhere else in the world.

The aye-aye primarily inhabits rainforests, deciduous forests, and sometimes cultivated areas near forest edges. These environments typically feature a tropical climate with high humidity and significant rainfall, supporting lush vegetation and diverse ecosystems.

The aye-aye is a nocturnal and arboreal primate, meaning it is active at night and lives primarily in trees. It occupies a unique ecological niche as a specialized forager, using its elongated middle finger to tap on trees to locate hollow cavities where grubs are present and then extract them for food. This adaptation allows it to exploit food resources that are inaccessible to many other species.
