599.53 -- Dolphins at play

Bottlenose dolphins are generally regarded as social and playful mammals. But did you know they can make their own "objects of play" underwater? They emit a ring of bubbles from their blowhole, then draw other rings out of it, bandy it about, and finally take a bite out of it, making the ring burst into many small bubbles. They do this over and over again. Check it out!



How cool is that?!
