Lemurs are mammals of the order Primates, divided into 8 families and consisting of 15 genera and around 100 highly diverse species — 105 to be exact. They are native only to the island of Madagascar.

Most lemurs are relatively small, have a pointed snout, large eyes, and a long tail. They are arboreal, living primarily in trees and nocturnal, preferring to be active at night, snacking on leaves and flowers, tree bark and sap. They are social animals, living in groups of a half dozen to up to 30 strong. The dominant female leads the group. Females have about one to size wee pups after mating with the sexiest, stinkiest males.

Phylogenetic, genetic, and anatomical evidence all suggest that lemurs split from other primates on Africa around 62 million years ago and that the ancestral lemur lineage had dispersed to Madagascar by around 54 million years ago. Once on the island, the lemur lineage diversified.
