[29] The average estrous cycle of the Virginia opossum is about 28 days. [30] Opossums do possess a placenta, [31] but it is short-lived, simple in structure, and, unlike that of placental mammals, not fully ...

Virginia opossum (Didelphis virginiana). Didelphimorphia is an order of marsupial mammals.Members of this order are called didelphimorphs, or opossums.They are primarily found in South America, though some are found in Central America and Mexico and one, the Virginia opossum, ranges into the United States and Canada.
The latter subclass is divided into two infraclasses: pouched mammals (metatherians or marsupials), and placental mammals (eutherians, for which see List of placental mammals). Classification updated from Wilson and Reeder's "Mammal Species of the World: A Taxonomic and Geographic Reference" using the "Planet Mammifères" website. [1]
Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene. They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail. Family: Didelphidae (American opossums) Subfamily: Didelphinae.

Didelphis is a genus of New World marsupials. The six species in the genus Didelphis, commonly known as Large American opossums, are members of the opossum order, Didelphimorphia. The genus Didelphis is composed of cat-sized omnivorous species, which can be recognized by their prehensile tails and their tendency to feign death when cornered.
