The koala is a marsupial native to Australia. Koalas feed almost exclusively on eucalypt leaves which are low in protein, difficult to digest, and even contain compounds that are toxic to many other animals. This diet means that koalas have a low metabolic rate (like sloths) and as a result spend many hours each day sleeping.
