Closeup of Red-bellied lemur couple, Marojejy, Madagascar

The red-bellied lemur (Eulemur rubriventer) is a medium sized strepsirrhine primate with a luxuriant chestnut brown coat. This lemur is endemic to eastern Madagascan rainforests and is distinguished by patches of white skin below the eyes, giving rise to a "teardrop" effect, particularly conspicuous in the male.
