The white shark searches for food visually, staying near 

 the sea bottom in water less than 90 feet deep (top) and 

 paralleling the ocean's surface in deeper water (bottom). 

 In both situations, the shark's dark back and light under- 

 belly blend with the surrounding environment, hiding the 

 shark from seals and sea lions, its usual prey.
