The fat-tailed dwarf lemur is one of the smaller members of the genus Cheirogaleus. Head-body length is 17–23 cm, tail length is 19–27 cm, total length is 40–50 cm, and body weight varies seasonally from 120 to 270 g (Petter, 1978; Fietz and Ganzhorn, 1999; Müller, 1999b; Groves, 2000). According to Groves (2000), the dorsal coat is a light frosted fawn-gray with a brown midline stripe. The ventral coat is creamy or yellowish, somewhat more yellow toward the median. There is a partial but sharply marked white collar that extends well up the sides of the neck. A white median facial stripe is offset by dark brown eye rings. The hands and feet are white. \([\dots]\) https://lemursofmadagascar.com
