The only native North American marsupial is the Virginia opossum, a solitary nocturnal animal and the largest type of opossum. It's a scavenger that eats roadkill, grass, nuts, fruit, mice, snakes, worms and small birds.
Marsupials are mammals that differ from other mammals in their anatomy and reproductive mode. The marsupial fetus does not fully develop in the mother's womb due to a lack of a placenta for nourishment. The newborns are tiny, blind and hairless. Immediately after birth, a baby marsupial crawls into its mother's pouch, where it receives nourishment from a nipple and is protected until it is able to care for itself. Australia and New Guinea are home to the most diverse population of marsupials, which include kangaroos, wallabies and koalas.
