Sand Wars - S1.E2

The sandy plains of the seabed can appear empty, but they actually hide multitudes of bizarre creatures, including masters of camouflage that disappear into the sands, fish that walk across the ocean floor and fish that appear to dance on their heads while hunting prey. Other marine life must hit the beaches to survive. Witness the epic journey that a leatherback turtle faces, dragging its 1,000-pound body to the top of the beach to lay its eggs.
