Virginia Opossum

Didelphis virginiana

Didelphis virginiana, the Virginia opossum, is a nocturnal marsupial native to North America and the only opossum found widely north of Mexico. It has a pointed face, naked ears, a scaly prehensile tail, opposable hind thumbs, and a pouch in which tiny newborns attach to teats and continue development. This adaptable animal uses forests, wetlands, farms, suburbs, and city edges, feeding on fruit, insects, carrion, eggs, small vertebrates, and human-associated scraps. Its well-known defensive response, often called playing possum, is an involuntary collapse with drooling and a strong odor rather than a deliberate trick.

Human contact is common because opossums den under sheds, cross roads at night, and appear around compost, pet food, or fallen fruit. They are wild animals rather than domestic pets, and many areas require permits for possession or rehabilitation. Orphaned young need trained wildlife rehabilitators, since incorrect feeding quickly causes illness. Coexistence usually means closing access points after animals have left, securing attractants, and keeping pets separated. In zoos and education settings, the species can be an effective ambassador for marsupial biology, but housing still needs secure climbing, hiding places, and a diet that prevents obesity.
