Wikipedia Abstract

The eastern woolly lemur (Avahi laniger), also known as the eastern avahi or Gmelin's woolly lemur, is a species of woolly lemur native to eastern Madagascar, where it lives in humid forests. This nocturnal animal weighs 1.0–1.3 kg and reaches a length of 27–29 cm with a tail of 33–37 cm. Its diet consists mainly of leaves and buds. Eastern woolly lemurs live in monogamous pairs together with their offspring.
