Eulemur collaris

Animalia, Lemuridae, EN

Eulemur collaris is a medium-sized lemur with a head-body length of 39–40 cm, a tail length of 50–55 cm, an overall length of 89–95 cm, and a body weight of 2.25–2.5 kg (Tattersall, 1982). This species is sexually dichromatic. In males, the dorsal coat is brownish-gray, the tail is darker, and there is also a dark stripe along the spine. The ventral coat is a paler gray. The muzzle, face and crown are dark gray to black. The creamy to rufous-brown cheeks and beard are thick and bushy, while the creamy to gray-colored eyebrow patches vary in their prominence. In females, the dorsal coat is browner or more rufous than that of the male. The ventral coat is a pale creamy-gray. The face and head are gray. The cheeks are rufous-brown, but less prominent than in the males. Both sexes have orange-red eyes. The red-collared brown lemur is similar in coloration to Eulemur cinereiceps. \([\dots]\) https://lemursofmadagascar.com
