"Mouse and dwarf lemurs win the cute award in the lemur family. They also inhabit all parts of Madagascar. These tiny bundles of fur are nocturnal, and have large eyes that help them see in the dark. Their appearance resembles that of a Bush Baby or a Tarsier, both of which happen to be cousins to the lemur. Dwarf lemurs have an unusually fat tail, because they hibernate during the winter, living off of fat that is stored in their tail."
