Photoblogging: More Koalas!

|

Check out the claws on this male (I think?) koala as he rests in the shade during the afternoon heat at the San Diego Zoo's "Koalafornia" exhibit. The koalas' curved, sharp claws help them to climb trees, and their two opposable digits on their front paws help them grasp branches as they climb. (We humans have only one opposable digit: our thumbs.)
