Genus: Caluromys. Derby's woolly opossum, Caluromys ...
In addition to the Greater Antillean sloths, some other pilosans are still extant on islands close to the Central and South American mainland. This includes several anteaters and a member of the other extant sloth family, that of the three-toed sloths , restricted to a small island in Panama. [ 10 ]

South America's 20 genera of nonhuman primates compares with 6 in Central America, 15 in Madagascar, 23 in Africa and 19 in Asia. All South American monkeys are believed to be descended from ancestors that rafted over from Africa about 25 million years ago in a single dispersal event. Suborder: Haplorrhini.

A number of sloths were also formerly present on the Antilles, which they reached from South America by some combination of rafting or floating with the prevailing currents. Together with the armadillos , which are in the order Cingulata, pilosans are part of the larger superorder Xenarthra , a defining characteristic of which is the presence ...

The pale-throated three-toed sloth (Bradypus tridactylus), which inhabits tropical rainforests in northern South America. It is similar in ...
