Didelphis virginiana
The Virginia opossum is North America's only marsupial. A marsupial is an animal with a pouch, like a kangaroo or a koala. The opossum has been around for at least 70 million years and is one of Earth's oldest surviving mammals! The opossum is about the size of a large house cat. It has a triangular head and a long pointed nose. It has grayish fur everywhere but on its ears, feet and tail. Its tail is prehensile. A prehensile tail is adapted for grasping and wrapping around things like tree limbs. The opossum can hang from its tail for a short time. Some people think opossums hang from their tails and sleep. They don't. Their tails aren't strong enough to hold them for that long! The opossum has opposable hallux. A hallux is like a thumb. The opossum's "thumbs" are on its rear feet. The hallux helps it grasp branches when it climbs. The opossum doesn't hibernate in the winter. It will often hole up during very cold weather because it runs the risk of getting frostbite on its hairless ears, tail and toes.
