The Red-bellied Lemur (Eulemur rubriventer) lives in the East-Madagascar rainforests, where it feeds on flowers, fruits and leaves and some toxic millipedes, which they drool on first, to neutralize the toxins. They exhibit both diurnal and nocturnal activities, though mainly diurnal. Females lead the groups foraging of about 5 lemurs. Lemurs use their lower incisors as a comb to groom troop members. They use, among other communications, chemicals to communicate. The prominent forehead scent gland of males is used to help mark territories..
The Red-bellied lemur is listed as Vulnerable (VU), considered to be facing a high risk of extinction in the wild, on the IUCN Red List of Threatened Species
