The Koala is a herbivorous marsupial.
A Koala's fur feels like velvet and is predominantly gray with white highlights, although Koalas from the southern part of their range tend to be more chocolate brown in colour and those from the northern part of their habitat tend to be more yellowish or whitish grey. A baby is called a "joey."
Koalas sleep about 22 hours each day! They eat only eucalyptus leaves, which provide little energy and few nutrients. This is why they must conserve their energy by moving as little as possible during daylight hours. An adult male can weigh up to 56 pounds (25 kilograms). An adult female weighs between 36 and 44 pounds (16-20 kilograms).
