Koalas are native to Australia, live in woodlands, and leaves of these trees are their main diet.
They are typically not social animals as they communicate only with their close family members. Koalas sleep for more than 20 hours a day. They get little energy from their diet, so they limit their energy use by less physical operations.
The koala has one of the smallest brains in proportion to body weight of any mammal and weighing approximately 19.2 g. Because of its small brain, the koala has a limited ability to perform complex and unfamiliar behaviors. For example, when given plucked leaves on a flat surface, it cannot adapt to the change in its normal feeding routine and will not eat the leaves.
The koala is popular worldwide and is a major attraction in Australian zoos and wildlife parks. They are featured in advertisements, games, cartoons, and as soft toys. It has boosted tourism in Australia as about 75% of European and Japanese tourists placed the koala at the top of their list of animals to see in zoos.
The koala is featured in the tales, stories and mythology of ancient Australians. Some believed that Koalas helped row the boat that brought them to the continent. Some stories tell of how the koala lost its tail. In one tale, a kangaroo cuts it off to punish the koala for being lazy and greedy.
In some parts of Australia, their population is declining to some extent, but their population is abundant in most of the continent.
