Koalas spend up to 22 hours a day sleeping. The rest of their time is spent eating & wandering around aimlessly searching for a mate. If they don’t find one, eventually they just give up & go back to sleep.
The koala or, inaccurately, koala bear, 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 are members of the family Vombatidae.
Koalas are dioecious animals that reproduce sexually. This means there are separate male and female koalas and a male and female are required to sexually mate, fertilization of sperm and egg, to produce offspring. Males attract females through vocal calls. These signals are critical for mating.
