The white shark is a macropredator, and is active during the daytime. Its most important prey are marine mammals(including, seals, sea lions, elephant seals, dolphins) and fish (including other sharks and rays).
Marine birds and sea otters are commonly found having suffered injuries from encounters with white sharks, but are rarely eaten by them. Great white sharks assess the energy value of prey in the first bite. If the prey doesn't have enough energy value to justify the energy needed for a full-scale attack, the shark releases it. If however the great white perceives the prey to be energy rich, it will give a devastating, powerful bite and wait for the prey to bleed to death. White sharks swallow creatures without chewing them, and can swallow objects half their size.
