The Didelphinae are a subfamily of opossums consisting of 15 genera and 123 species. [2] [3] [4] Specimens have been collected throughout the Americas, but are predominant in South and Central America. [5]
Some sources call this subfamily the "American opossums", [2] [6] while others use that term for the whole family of opossums, Didelphidae. [1] The term may be redundant, though, since all opossums are native to the Americas, while their distant Australian taxonomic relatives, in the suborder Phalangeriformes are referred to as possums in Australia.
Opossums are members of the marsupial order Didelphimorphia endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 120+ species in 19 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America.
