Field Notes

Description:

Opossums (Didelphimorphia, /daɪˌdɛlfɨˈmɔrfiə/) make up the largest order of marsupials in the Western Hemisphere, including 103 or more species in 19 genera. They are also commonly called possums, though that term technically refers to Australian fauna of the suborder Phalangeriformes. The Virginia opossum was the first animal to be named an opossum; usage of the name was published in 1610. The word opossum comes from the Proto-Algonquian aposoum, pronounced *wa˙p- aʔθemw, meaning "white dog" or "white beast/ animal". Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene.

Their unspecialized biology, flexible diet and reproductive strategy make them successful colonizers and survivors in diverse locations and conditions.

Habitat:

This one was discovered in my backyard.

Notes:

One of my dogs discovered this opossum in the late afternoon, under a bird of paradise plant. I went to put my dog inside and when I came back he had crawled away through a hole in the fence. It was covered with flies, I'm not sure why.

Thanks for commenting, Satyen. Good information, Emma! Thanks.
Opossums have 50 teeth: 1/2 of upper jaw: 5 incisors, 1 canine, 3 premolars, and 4 molars. 1/2 of bottom jaw: 4 incisors, 1 canine, 3 premolars, 4 molars. Looks like the incisors are very tiny.
