Blowing bubble rings is one of the more entertaining ways to pass the time underwater, and humans aren’t the only mammals that get a kick out of it. Cetaceans are actually quite adept at making bubble rings, and even appear to do it just for fun! It is thought that dolphins are able to perceive the bubbles with sonar, but research is still underway to determine why they make them in the first place, and if it is learned behavior or inherited ability. Whatever the answers to these questions may be, there can be no doubt that these creatures are masters of self-amusement!
