The Koala is the only member of the Phascolarctidae family. The Koalaâs scientific name Phascolarctos cinereus means âash-coloured pouched bearâ. Some people refer to the Koala as a Koala Bear. Although it looks like a small bear, the Koala is a marsupial mammal. Female marsupials have pouches to carry their babies. Other marsupials include kangaroos, wallabies, wombats, possums, and opossums. The Koalaâs closest relative is the wombat.
