Beyond the beaches and waves of Southern California is one of America's greatest wilderness areas. In these warm Pacific waters, sea lions, otters and grey whales explore the mysterious folds of kelp forests. Angle rays and star fish turn seemingly barren sand flats into a battle ground, while vibrant coral reefs are flush with life. And some of the most bizarre and awesome creatures ever to have lived - giant jellyfish, basking sharks and the blue whale - follow the rich, open ocean currents of plankton and krill. It is an amazing chain of life that exists in harmony with itself yet governed by the unique cycles of regeneration and tidal rhythms that define the sea.
