A great white shark opens it mouth just before it attacks its prey with a crippling, powerful bite. After the prey has been disabled, the shark will often wait for it to weaken from blood loss before resuming the attack. If the shark looses a tooth in the course of the bite, a replacement just behind it will move forward to take its place.
