The term 'marsupial american' refers to two species of marsupials native to the Americas. The first is the OPOSSUM, which is a seven-letter word. Opossums are small mammals that are found in North and South America. They have a distinctive pouch on their abdomen where they carry their young. The second species is the WOMBAT, which is a six-letter word. Wombats are found in Australia and are burrowing animals that are related to the koala. They have a thick, protective hide and short, stubby legs. Both the OPOSSUM and the WOMBAT are marsupials, meaning they are mammals that carry their young in a pouch.
