The two-toed sloth is a species of sloth found in Central and South America. It is also known by its scientific name, Choloepus didactylus, and is the only extant member of the genus Choloepus. The two-toed sloth is a slow-moving mammal that spends most of its time in trees, where it feeds on leaves, fruits, and flowers. Its name comes from the two long claws on each of its front feet. The two-toed sloth is an important part of the ecosystem in its native range, providing food for predators such as jaguars and ocelots. The four-letter word UNAU is the Spanish name for the two-toed sloth.
