Koalas aren't bears. The koala is a mammal related to the kangaroo and wombat. The reason the koala is called a koala bear is because the koala looks like a teddy bear. The koala's scientific name is Phasclarctos cinereus.
Now there are only 2,000 to 8,000 koalas in the wild! Although not officially classified as endangered, the population of Australian koalas has dropped by 90% in less than a decade!
