The Virginia opossum is the only marsupial (pouched mammal) found in the United States. The Opossum has been around for at least 70 million years - since the time of the dinosaurs - and is one of Earth's oldest surviving mammals. They are unusually resistant to the venom of venomous snakes and are extremely unlikely to acquire rabies. They have 50 very sharp teeth, more than any land mammal. 

The Virginia opossum has many behavioral adaptations it uses to survive. When threatened, it will exhibit behaviors like running, growling, belching, urinating and even defecating. Sometimes it will "play 'possum" and roll over, become stiff, drool, and its breathing will become slow and shallow. This coma-like state can last up to four hours. Predators will think the opossum is dead and go away.

The name 'opossum' was first used in western culture by Captain John Smith in 1608. It comes from the Algonquin name 'apasum', which means 'white animal.'
