Great white shark is one of the most widely distributed sharks, because it has an unusual ability to keep its body temperature higher than the ambient temperature, which enables it to live comfortably in very cold sea water. Although it is hard to see in most coastal areas, fishing boats and diving boats often meet unexpectedly.

The great white shark is also famous for its curiosity-it often looks up from the water, and what worries people in the water is that it often explores unfamiliar targets by biting.
