Madagascar, home of the lemur, is one of the global hotspots for endemic species. There are five families of lemurs with 99 species and subspecies. The smallest lemur would easily fit in your hand, while the largest can top 25 pounds. Many lemurs live in matriarchal societies where females call the shots. Most species spend the majority of their time in the trees and travel the forest canopy climbing and leaping — as agile as any monkey. Sadly, most species are also listed as endangered or threatened and some have fallen into extinction in the last few hundred years.
