Didelphis virginiana
The Virginia opossum, commonly known as the North American opossum or tlacuache in Mexico, is the only marsupial found in North America north of Mexico. A solitary and nocturnal animal about the size of a domestic cat, and thus the largest opossum, it is a successful opportunist. Virginia opossums can vary considerably in size, with larger specimens found to the north of the opossum's range and smaller specimens in the tropics. They measure 13–37 inches (35–94 cm) long from their snout to the base of the tail, with the tail adding another 8.5–19 inches (21.6–47 cm). Weight for males ranges from 1.7 to 14 pounds (0.8–6.4 kg) and for females from 11 ounces to 8.2 pounds (0.3–3.7 kg). They are one of the world's most variably sized mammals, since a large male from northern North America weighs about 20 times as much as a small female from the tropics. Their coats are a dull grayish brown, other than on their faces, which are white. Opossums have long, hairless, prehensile tails, which can be used to grab branches and carry small objects. They also have hairless ears and a long, flat nose. Opossums have 50 teeth, the most out of any North American mammal, and opposable, clawless thumbs on their rear limbs. Opossums have thirteen nipples, arranged in a circle of twelve with one in the middle.
The Virginia opossum is found throughout Central America and North America east of the Rockies from Costa Rica to southern Ontario; it seems to be still expanding its range northward and has been found farther north than Toronto. In recent years their range has expanded west and north all the way into northern Minnesota. Its ancestors evolved in South America, but invaded North America in the Great American Interchange, which was enabled by the formation of the Isthmus of Panama about 3 million years ago. Originally native to the eastern United States, it was intentionally introduced into the West during the Great Depression, probably as a source of food, and now occupies much of the Pacific coast. Its range has been expanding steadily northwards into Canada.
These babies were rescued by our babysitter's family. They stopped to check on an adult that had been hit and noticed it was a female. She was dead and had 5 little ones still clutching on to her lifeless body. They carefully scooped them up and brought them to me, and I got them to a licensed rehabber the next day. All 5 grew up and were eventually released.
