Propithecus edwardsi

Animalia, Indriidae, EN

Propithecus edwardsi is a large dark sifaka. It has a head-body length of 42–52 cm, a tail length of 41–48 cm, a total length of 83–100 cm, and a weight of 5.0–6.5 kg (Glander et al., 1992; Lehman et al., 2005a). Its dorsal coat is dense and dark, varying from chocolate- brown to almost black on the head, upper body, limbs, and tail. Bilateral whitish patches of varying extent grade into the darker surrounding fur on the back and flanks, sometimes meeting along the spine. The ventral coat is equally dark, sometimes paler around the area of the chest, but less dense than the dorsal coat. The face is bare and the skin is dark gray to black, as are the ears that are barely discernible above the dark fur of the head. The eyes are orange-red. This species is very distinctive and cannot be confused with any other sympatric species. \([\dots]\) https://lemursofmadagascar.com
