What do they look like?
The koala is a tree-dwelling marsupial with large furry ears, a prominent black nose, long sharp claws adapted for climbing and no tail. Fur colour varies from pale grey in north Australia to grey-brown in the south.
Koalas also vary in size across their range. Adult males weigh between 4 and 14 kilograms and adult females weigh between 4 and 10 kilograms.
Despite being called 'koala bears' for many years, koalas are marsupials. While bears give birth to well-developed young, newborn koalas are tiny enough to fit on your thumbnail, and are raised in their mother's pouch.
The closest relative of the koala is the wombat. Both animals have pouches which open towards the rear. This is fine for the wombat, but koalas need strong muscles ringing the pouch to keep their young from falling out.
Why are they special?
- People have a close affinity with the koala.
- Koalas benefit the Australian economy. It has been estimated that they create over 9,000 jobs and contribute between $1.1 billion and $2.5 billion per year to tourism in Australia.
- Koalas feature in many Aboriginal dreaming and creation stories and are a totemic species.
- Although the koala’s Latin name, Phascolarctos cinereus, means ‘ash-coloured pouched bear,’ the koala is not a bear but a marsupial whose closest relative is the wombat.
- Koalas are one of the few animals, along with ringtail possums and greater gliders, that feed exclusively on eucalyptus leaves.
