Propithecus coronatus

Animalia, Indriidae, EN

Propithecus coronatus is a medium-sized, predominantly white sifaka from western Madagascar. It has a head-body length of 39–45 cm, a tail length of 48–57 cm, a total length of 87–102 cm, and a weight of 3.5–4.3 kg (Tattersall, 1982; Mittermeier et al., 1994). The coat is creamy-white, which contrasts strongly with the chocolate-brown to black head, neck and throat. The muzzle is blunt and rounded, and even bulbous in form, and the face is naked and black. The bulbous nose is quite unusual and readily distinguishes this sifaka from all others. There is sometimes a patch of white fur across the bridge of the nose and slight white tufting around the ears. The body coat is variably tinted golden-yellow to golden-brown on the upper chest, shoulders and upper forelimbs. \([\dots]\) https://lemursofmadagascar.com
