Central American woolly opossum Caluromys derbianus, photographed by Adam von Haden.

Belongs within: Marsupialia.
Contains: Didelphinae.

The Didelphidae includes the opossums of North and South America (some sources divide them between the Didelphidae sensu stricto and Caluromyidae, but the ‘Caluromyidae’ are probably paraphyletic to the other didelphids). Morphological synapomorphies for the Didelphidae remain uncertain, but the monophyly of this clade is supported by molecular analysis, and side-by-side epididymal sperm-pairing has been found in all species investigated for this trait (Jansa & Voss 2005).
