There are over 330 species of marsupials. Around two-thirds of them live in Australia. The other third live mostly in South America, where some interesting ones include the flipper-wearing yapok, bare-tailed woolly opossum, and don’t get too excited, but there’s also the gray four-eyed opossum.
What is an animal that looks similar to a kangaroo?
Brush wallabies of the genus Notamacropus, like the agile wallaby (Notamacropus agilis) and the red-necked wallaby (Notamacropus rufogriseus), are most closely related to the kangaroos and wallaroos and, aside from their size, look very similar.

What is the biggest carnivorous marsupial?
The Tasmanian devil

Why are marsupials only found in Australia?
Why are the majority of current-day marsupials found in Australia? One line of thinking is that marsupial diversity is greater in Australia than in South America because there were no terrestrial placental mammals to compete with marsupials in ancient Australia.
What kind of marsupial has brown and gray fur?
The wombat, which the National Geographic website describes as “pudgy,” is a burrower marsupial with brown or gray fur. Like a koala, a wombat’s pouch faces the legs to keep dirt out as the animal digs. Wombats are herbivores that feed on grasses, roots, tubers and even tree bark.

There are three species: the common wombat, northern hairy-nosed wombat and southern hairy-nosed wombat. Hairy-nosed wombats have larger ears and softer fur than common wombats.
Are there any placental parallels to marsupials?
Present marsupial faunas are very diverse, with some startling parallels with placental mammals (e.g., marsupials with similar morphologies and life histories as moles, anteaters, shrews, primates, carnivores, and many others). Some marsupial life histories and morphologies are seemingly without placental mammal parallels, for example, kangaroos.
