Ruffed lemurs are the largest lemur species. They live in the tropical rainforests of Madagascar. There are two ruffed lemur subspecies identified, the Red and the Black-and-white ruffed lemur. Ruffed lemurs live in the foliature, where they spend most of the day with resting and sunbathing. They live in smaller families of 2-5 individuals led by the female of the highest rank. Ruffed lemur groups protect their territory with earsplitting howling.
