Propithecus verreauxi, one of the smaller sifakas, is a pale form from southern and southwestern Madagascar. It has a head-body length of 40–48 cm, a tail length of 50–60 cm, a total length of 90–110 cm, and a weight of 3.0–3.5 kg (Tattersall, 1982; Kappeler, 1991; Richard et al., 2000, 2002). The pelage is long and thick, and the predominant coat color, including the tail, is white. This contrasts sharply with the black face, muzzle, hands and feet, the dark brown crown that extends down the nape of the neck in both sexes, and the reddish-brown patch found on the upper chest of males that is associated with their sternal glands. Fur on the ears is white and slightly tufted. \([\dots]\) https://lemursofmadagascar.com
