36. Kangaroo and joey.
Sightseeing in Melbourne picture - A kangaroo and her joey at the Wildlife Wonderland at Bass Strait, Victoria. Australians refer to kangaroo calves as 'joeys'. At the slightest sign of danger, the joey dives head first into his mother's pouch, then turns round and sticks his head out. Even this large-ish joey could manage to do that.
