The ventral areas are typically lighter and the tail is usually brown or black. [ 7][ 8] The muzzle is marked with dark patches.

The Virginia opossum (Didelphis virginiana), also known as the North American opossum, is the only opossum living north of Mexico, its range extending south into Central America. It is the northernmost marsupial in the world. In the United States and Canada, it is typically called a possum which technically refers to a different group of ...
Much of this success can be attributed to sustained possum control reducing cross-infection and breaking the disease cycle. For example, at Hohotaka, in New Zealand's central North Island, control work from 1988 to 1994 achieved a sustained mean reduction of 87.5% in the density of TB‐infected possums. As expected, annual TB incidence in ...
The largest difference between the opossum and non-marsupial mammals is the bifurcated penis of the male and bifurcated vagina of the female (the source of the term didelphimorph, from the Greek didelphys, meaning "double-wombed"). [38] Opossum spermatozoa exhibit sperm-pairing, forming conjugate pairs in the epididymis.
