The opossum (also called possum) is the only marsupial (female with a pouch) in North America. They are about the size of a cat, have black to gray fur, and long, pointed noses (pink in color). Opossums have many teeth, more than any other land mammal, and a prehensile tail, one that can grasp or hold.
