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. They have a variety of sizes, shapes, and fur patterns, and range in size from the 6 cm (2 in) (plus 9 cm (4 in) tail) Kalinowski's mouse opossum to the 55 cm (22 in) (plus 54 cm ...
