It is a bit of an understatement to say that dolphins are incredibly intelligent animals. Many have even figured out how to make their own toys…from blowing bubbles.
This behavior is not limited to the dolphins at SeaWorld, dolphins in the wild blow bubble rings and beluga whales make rings too.
Bubble rings and smoke rings, their above water sibling, are both examples of a complex physical phenomenon called a vortex ring, which is basically a puff of air that has curled back around on itself and then keeps spinning, creating a doughnut shape.
Pretty cool, huh?
