10. To hunt fast and agile prey such as sea lions, the great white has adapted to maintain a body temperature warmer than the surrounding water. It is able to conserve heat within the body by warming the cooler arterial blood with the venous blood that has been warmed by the working muscles. This allows the shark to keep certain parts of the body, such as its stomach, at temperatures of up to 14 °Celsius higher that of the surrounding water.
