Great white shark = fear!!! many people think that the great white shark wants to eat people whenever they discover one in the water, but that is not so. Many more sharks die because of people. The shark does not want to kill people. He is very curious and responds to small noises and movements; this is why he sometimes takes a "test bite" to determine if it is a prey or not. Unfortunately, even the smallest bite of a great white shark can be fatal for humans. The great white shark usually eats seals, harbor seals, sea Lions, dolphins, Turtles, tuna, birds and even other sharks. However, they rarely eat; it depends on the size of the prey.
