Koala 'bear'

Koalas aren't bears. They're marsupials. I took this photo at Healesville Sanctuary a few weeks ago.

Koalas have two thumbs on each hand. You can't see both thumbs in this picture, but you can see the very long nails on the hands. They use these nails to help them scoot up and down trees. Koalas seem quite lazy, really, except for when they are whizzing up and down trees. They eat only one kind of leaf (how boring): the eucalyptus leaves below the koala in this picture.

One of the interesting things about koalas is that they have a hard pad at the base of their spine, around where we have our coccyx. This hard pad is what they sit on, in the crooks of trees. It's like a built-in cushion.

Pretty darned cute, isn't it? (Particularly the ears.)
