Propithecus coquereli is a medium-sized, predominantly white sifaka of northwestern Madagascar. It has a head-body length of 42–50 cm, a tail length of 50–60 cm, a total length of 93–110 cm, and a weight of 3.7–4.3 kg (Tattersall, 1982; Kappeler, 1991; Ravosa et al., 1993). The pelage is dense. The dorsal coat color is mostly white, including the head and the tail. Prominent maroon patches cover the chest, the anterior and interior aspects of the forelimbs and hindlimbs, and sometimes the base of the back. The skin of the muzzle and face is bare and black, except for a white patch of fur extending across the bridge of the nose. The ears also are black, naked, and visible above the white fur of the head and cheeks. The eyes are yellow. \([\dots]\) https://lemursofmadagascar.com
