First time I saw this in a shorter clip I was skeptical because of the way the bubbles moved defying buoyancy. But, after watching this longer version it appears to me that the dolphins are creating eddies that control the movement of the bubble rings.
Might be good for animal learning topics, to launch a discussion on creativity (are we seeing artistic creativity in the dolphins and how do we operationalize creativity, etc.). http://www.youtube.com/watch?v=wuVgXJ55G6Y -- Paul Bernhardt Frostburg State University Frostburg, MD, USA --- To make changes to your subscription contact: Bill Southerly ([email protected])
