Through my research I learned that koalas have strange hands. There is a picture of the hands on my backdrop. The hand has two thumbs for clinging to the trees. The claws are very, very sharp. That is why you rarely hear about koalas falling out of trees.
Koalas have very interesting teeth.
They have eight teeth for cutting, two for ripping the leaves off of the tree, and twenty for chewing and grinding the leaves and bark. I thought that the teeth were all for the same things, but I guess I was wrong. I did not find how many teeth a baby koala has when it is first born or if they grow in as they grow up like humans. A koala's young is called a joey. I have always thought that a baby koala is called a baby koala.
