Duration: 02:23

Bottlenose dolphins are one of the fastest animals on Earth and the ones off the coast of Florida have invented a new way of hunting their elusive and fast swimming prey. Swimming in ever decreasing circles the dolphins stir up the mud from the sea floor with their tails, and trap schools of fish inside the resulting ring of mud. The panicked fish jump out of the water away from the ring and straight into the waiting mouths of the other dolphins. Developing this sort of advantage over other groups of bottlenose dolphins may give this population the edge in the battle for survival of the fittest.
