The sportive lemurs (the family Lepilemuridae)

The sportive lemurs are the medium-sized primates that make up the family Lepilemuridae. The family consists of only one extant genus, Lepilemur. They are closely related to the other lemurs and exclusively live on the island of Madagascar. For a time, this family was named Megaladapidae, but the current name was given precedence since the extinct genus Megaladapis was removed from the family.

Appearance

Lepilemuridae are medium-sized wet-nosed primates that form the family Lepilemuridae. The family includes an extant genus, Lepilemur, and the extinct genus Megaladapis.

For a time, this family was called Megaladapidae, but the current nomenclature is used since a specific taxon was created for the extinct genus Megaladapis.

They differ from other lemurs in several respects and live exclusively in Madagascar.

Physical characteristics

Their fur is grey brown or reddish colored on the top and whitish yellow underneath. They typically have a short head with large, round ears. They grow to a length of 30 to 35 cm (12 to 14 in) (with a tail just about as long as their body) and weigh up to 0.9 kg (2 lb). Their eyes have a tapetum lucidum behind the retina, hence they have eyeshine.

Behaviour and ecology

Sportive lemurs are strictly nocturnal and predominantly arboreal, moving among the trees with long jumps powered by their strong hind legs. On the ground, they hop similarly to the kangaroo. During the day they hide in leafy covering or tree hollows. Sportive lemurs are mostly solitary and defend their territory against same sex intruders. The territories of males and females can overlap.

They are mainly herbivores and their diet consists predominantly of leaves.

Birthing happens between September and December after a gestation of 120 to 150 days, and is usually of a single young which is often reared in a nest in a tree hollow. At about four months the juveniles are weaned but remain with their mother up to an age of one year. At about 18 months they are fully mature, and live to be about eight years old.
