We often hear these adorable Aussies called ‘koala bears’, but they are actually not bears at all. Koalas are marsupials, so they carry their young in a pouch, unlike bears which carry their young in the womb until they are well developed. The koala lives almost entirely on eucalypt leaves and they have a very low metabolic rate for a mammal, which is why they can sleep for up to 20 hours a day!
Fact about Koalas
Koalas have the largest appendix of any mammal. It grows to a length of two metres.
