Eulemur flavifrons

(Gray, 1867), Animalia, Lemuridae, CR

Eulemur flavifrons is a medium-sized lemur with a head-body length of 39–45 cm, a tail length of 51–65 cm, a total length of 90–100 cm, and a weight of 1.8–1.9 kg (Terranova and Coffman, 1997; G. Randriatahina, pers. comm.). This species is sexually dichromatic. In males, the dorsal and ventral coats are black, the hairs sometimes tinged with brown, and a distinct ridge of hair on the forehead forms a noticeable crest. In contrast to E. macaco, with which it was long considered conspecific, there are no ear tufts. In females, the dorsal coat is reddish-tan to reddish-gray. The ventral coat is creamy-white to gray. The hands and feet are darker gray. The muzzle is slate-gray, the face lighter, and the crown rufous-tan. As with males, and again in contrast to female E. macaco, there are no ear tufts. The eyes of both sexes are blue to blue-gray, making this species one of the very few primates in the world that consistently has blue eyes, hence the common English name. \([\dots]\) https://lemursofmadagascar.com
