Have you ever heard someone call a koala "koala bear"? Well, like bears, koalas are mammals, with round and fluffy ears that look cute, just like a teddy bear. But koalas are not bears. They are members of a group of marsupials known as marsupials. Marsupials include kangaroos, wallabies, kangaroos, wombats, possums, and possums. Koalas look soft, but their fur feels like sheep's shag. They also look cute, but koalas are not tame and they are not good pets.
