Dolphins blowing bubble rings at Seaworld.

The dolphins at SeaWorld Orlando’s Dolphin Cove have taught themselves a new trick. They’ve figured out how to blow bubble rings – like smoke rings only made of air – from their blow holes which they then manipulate under the water. It’s a behavior that they’ve taught themselves how to do as none of the trainers were involved. It’s absolutely amazing to see:

We already know they’re highly intelligent animals and I can only imagine how boring being a part of an exhibit can be for them. This is apparently something they’ve come up with to amuse themselves.
