Avahi occidentalis

(Lorenz, 1898), Animalia, Indriidae, EN

Avahi occidentalis is one of the smallest woolly lemurs and consequently among the smallest members of the family Indriidae. It has a head-body length of 26.9–30.3 cm, a tail length of 30.7–37.7 cm, a total length of 57.6–68.2 cm, and a weight of 800–1,100 g (Bauchot and Stephan, 1966; Thalmann and Geissmann, 2000; Thalmann, 2001; Zaramody et al. 2006; Lei et al., 2008). It is lighter in color than A. laniger, with the dense, tightly curled fur of the back a light to medium gray, sometimes flecked with brown or olive, becoming paler towards the rear. Typically, the tail is gray as well, but can sometimes be reddish. The face, throat and cheeks are pale, not brown as in A. laniger. \([\dots]\) https://lemursofmadagascar.com
