Like the Blue-Eyed Lemur, the adult Collared Lemur can be about the size of a large house cat, weighing about 5.7 lbs (2.6kg) with a body length of 16 inches (41cm), with a tail as long as 22 inches (55cm). It can live 20-25 years.
Males are brownish-gray with a dark stripe down the back, a dark tail and tail tip, and a lighter underside. Females have a reddish to brown coat and a gray face. Both sexes have a distinct beard that is reddish-brown in females and cream to reddish-brown in males. Collared lemurs are distinguished from the very similar white-collared lemurs by a slightly darker beard.
