Didelphimorphia (opossums)

Didelphimorphia
There is one family in this order with about 60 species. They are marsupials and most are the size of a house cat. Most of them are gray or brown in color and live in Central and South America. One species, the Virginia opossum, is found in North America. Opossums have a prehensile tail and some, but not all, have a pouch. A prehensile tail can curl around things. Most species are omnivorous, but some species are carnivorous. Most opossums are nomadic and don't have a permanent den or burrow.
