Cheirogaleus É. Geoffroy, 1812

Prosimian genus to which the dwarf lemurs belong; located throughout Madagascar. There are two recognized species. Small (body mass 150-600 g), nocturnal (possess tapetum lucidum); arboreal quadrupeds. Dental formula:; predominantly frugivorous. Dental comb present; grooming claw on second digit of hind paw. A characteristic of dwarf lemurs is their thick tails, in which fat is stored and used during seasonal torpor during the dry southern winter of Madagascar. During the day and during hibernation, individuals form balls of several animals for heat conservation and congregate in sleeping dormitories in hollow trees; however, during their active cycle they are noyau and the females have home ranges that are overlapped by the male home ranges.
