The average body mass is around 3.6 kilograms. Like other true lemurs this species has a rhinarium at the end of its snout. The females of this species have three pairs of mammary glands. Also in females, the vulva is only open during estrus.
This species is found in Madagascar along the East coast living in the canopy of the rainforests.
This is primarily a frugivorous species.
This arboreal species moves quadrupedally through the trees.
This is a monogamous species in which the pair and its offspring form the social group.
alarm call: this call starts out as a grunt, but with duration turns into a roar.
contact calls: these calls between mother and infant tend to be soft in volume.
As with all of the true lemurs, olfactory communication is important for this species. Anogenital secretions seem to be important for the ruffed lemur.
Typically this species gives birth to a single offspring, however twins have been observed. The females are only fertile for one day out of the year (Fleagle, 1988).
