I've read this entire thread and I have to put an end to this stupid petty,(although I'm on hookers with machineguns side) and ridiculous argument to rest. The reason the koala is called a koala bear is because the koala looks like a teddy bear, if you want to get technical (pay attention Covel) they are called 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!
Did you know that???
