The Beauty of Marine Mammals and Their Toroidal Bubbles

A bubble ring, or toroidal bubble, is an underwater vortex ring where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins poloidally as it travels through the water, much like a flexible bracelet might spin when it is rolled on to a person’s arm. The faster the bubble ring spins, the more stable it becomes. Bubble rings and smoke rings are both examples of vortex ringsā€”the physics of which is still under active study in fluid dynamics. Devices have been invented which generate bubble vortex rings. (Source- Wikipedia)

    Why do marine mammals do this and why do they seem to exhibit a playful behavior when they do it?
