Robot that swims like a sea mammal

Here's a robot which looks like the Loch Ness sea monster but which comes to us straight from Japan. A hybrid between a kind of worm and prehistoric monster. It has to be admitted that the prototype is pretty successful and you would easily say it looks like a real sea mammal. You can see other aquatic robots in action on Youtube youtube.com/user/EBIMAYA http://www.youtube.com/watch?v=EijCwsa8QcQ via r-d
