Furry-eared Dwarf Lemur (Cheirogaleus crossleyi)
The dental formula of this species is 2:1:3:3 on both the upper and lower jaws (Ankel-Simons, 2000). The furry-eared dwarf lemur has a pelage coloration that is red-brown dorsally and gray ventrally (Groves, 2000). The eye-rings of this species are blackish and the ears are black inside and out (Groves, 2000).
The furry-eared dwarf lemur is found in the country of Madagascar (Groves, 2000). This species has been seen in Imerima, Lake Alaotra, Perinet, Malewo, Antsianaka, and Vohima (Groves, 2000).
The furry-eared dwarf lemur is a nocturnal and an arboreal species.
The furry-eared dwarf lemur is an arboreal quadruped, and is not a very agile leaper (Fleagle, 1988).
squeak: This call is high in pitch and plaintive sounding and is emitted with the mouth closed (Petter and Charles-Dominique, 1979). This call is usually emitted by an infant and serves the purpose of a contact call, that is the infant desires the same call from its mother to keep in contact (Petter and Charles-Dominique, 1979). This call is also heard during allogrooming between adults (Petter and Charles-Dominique, 1979).
whistle: This call is high-pitched and is hard to hear with human ears (Petter and Charles-Dominique, 1979). This call is emitted by adults of both sexes and serves as a distant communication call and possibly a territorial call (Petter and Charles-Dominique, 1979).
grunt: This call is high-pitched and powerful in nature and also given in a series (Petter and Charles-Dominique, 1979). This call is given when an individual is attacked or disturbed in the nest (Petter and Charles-Dominique, 1979). At the same time the individual will try to retreat when giving this call, and will also sometimes lunge out and try to bite at what is disturbing it (Petter and Charles-Dominique, 1979).
