Boing Boing posted this video today and I'm in love with the science. Animal locomotion is a peculiar study from both mechanical and evolutionary perspectives. The snakebot can not only climb but swim, which is an entirely different kind of motion if you've ever seen a snake in the water. It blew my mind to read that some bats can swim as well, using their wings as oars. Other aquatic bio-robotics include the jellyfish bots.
