They sleep about 18 hours each day supposedly because of the low nutritional value of their diet. It takes about two weeks to digest the eucalyptus leaves they eat. Must be hard being a koala.
18 hours is the minimum. They can sleep up to 22 hours a day, which means being awake for only 2 hours, not 6!

it has accepted koala bear for me. Never knew that other speakers of English truncated the name to koala
