Microcebus murinus

Animalia, Cheirogaleidae, LC

The gray mouse lemur has a head-body length of 12–14 cm, a tail length of 13–14.5 cm, a total length of 25–28 cm, and a weight of 58–67 g (Rasoloarison et al., 2000). The dorsal coat is brownish-gray with various reddish tones, the flanks are light gray to beige, and the ventral fur has discrete dull beige or whitish-beige patches along portions of the belly. A pale white patch occurs above the nose and between the eyes; some individuals have dark orbital markings. The furred portions of the hands and feet are off-white. The ears are long and fleshy in comparison to the shorter, more concealed ears of Microcebus rufus. This species can be distinguished from the often sympatric Cheirogaleus medius by its smaller size and more active movement, and from Mirza coquereli by its smaller ears and smaller size. Phaner, Lepilemur, and Avahi are all considerably larger and unlikely to be confused with this species. \([\dots]\) https://lemursofmadagascar.com
