Dolphins: Not so tiny bubbles
Over 3 million people have already watched the YouTube video of dolphins engaging in their characteristic behavior of blowing bubbles, but if you haven’t seen it, I hope you will watch it immediately! It is delightful, interesting, intriguing, and fascinating, and there is commentary in a longer version about how and why they do it. There are several versions of this extraordinarily beautiful phenomenon, and a short segment of an “awesome underwater bubble ring” all by itself that I found spell-binding. There is a website devoted to dolphins and their bubble blowing you can find here.
