The koala is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats, which comprise the family Vombatidae.
Like most marsupials, the Sulawesi bear cuscus is an herbivore, eating only vegetation. Its diet consists mostly of leaves, along with flowers, buds and unripe fruit. Due to the low nutrient level in much of its diet, the cuscus tends to move slowly and spend a large portion of the day resting in order to digest its food.
Both are marsupials, both sleep a lot, neither are bears.
