Opossum

Opossums are 65 species of marsupial mammals constituting the family Didelphidae. They are the only marsupials found outside the Australian region, and all but one species are found from Mexico south through Argentina. The only species established north of Mexico is the common opossum, Didelphis marsupialis, which ranges as far north as southern Canada. The common opossum grows to about 53 cm (21 in) long, plus a hairless 33 cm (13 in) tail; it stands about 18 cm (17 in) high at the shoulder and may weigh up to 6.3 kg (14 lb). The opossum's coat is coarse and commonly gray, with white guard hairs, the snout is white, and the tail is black for about half of its length or less. There are five toes on each foot, and the long, pointed muzzle contains 50 teeth and can be opened beyond 90^o. Opossum are most active at night.

Virginia opossum can be found in most of the United States east of the Rocky Mountains and on the West Coast. It is also found in Mexico, Central America and in British Columbia, Canada.
