Koala Fun Fact: A fun fact about koalas is that they sleep for up to 18-22 hours a day! This is because their diet consists mainly of eucalyptus leaves, which are low in nutrients and take a lot of energy to digest. To conserve energy, koalas spend most of their time resting in trees, making them one of the sleepiest animals in the world.
