Red-bellied Lemur (Eulemur rubriventer)

Red-bellied lemur Mittermeier et al. [1994] report a body length for Eulemur rubriventer of just under 40cm. Mean body weight is 2067g for males (n=9) and 1960g for females [n=13; Glander et al., 1992]. The species occurs at low densities throughout most of the forested eastern escarpment [Petter & Petter, 1971; Tattersall, 1982; Jolly et al., 1984]. Population size has been estimated to be 10,000-100,000 individuals [Mittermeier et al., 1992], and the red-bellied lemur is classified as Vulnerable by the IUCN. In European zoos there were 140 E. rubriventer living as at January 2012. They are recorded in a European Studbook maintained by Mulhouse Zoo.


Red-bellied lemurs feed predominantly on fruits, but also on flowers, leaves and invertebrates [Meier, 1987; Dague & Petter, 1988; Overdorff, 1991]. Regarding their degree of frugivory and their feeding strategy, this species is probably comparable to the ruffed lemur.
