Daubentonia madagascariensis

(Gmelin, 1788), Animalia, Daubentoniidae, EN

The aye-aye (Daubentonia madagascariensis) is one of Madagascar’s truly unique flagship species, and the most unusual and distinctive primate on Earth. A medium-sized lemur, with a head-body length of 30–37 cm, a tail length of 44–53 cm, a total length of 74–90 cm, and a body weight of 2.5–2.6 kg (Glander, 1994; Mittermeier et al., 1994; Feistner and Sterling, 1995). The aye-aye is immediately recognizable by its prominent black, highly mobile ears, its long thin fingers and toes, and its long bushy tail. Its overall appearance is a dark grayish-brown. The dorsal coat, including that of the limbs, consists of a dense layer of short, off-white hairs overlaid by a longer, coarser layer of blackish- brown, white-tipped guard hairs, giving the animal a brindled appearance. The tail is darkly colored and its hairs are monochromatic. The ventral coat is similar to the dorsal coat in hair pattern, but not as dense, and turns whiter on the chest, throat and face. \([\dots]\) https://lemursofmadagascar.com
