Humans atack

The white shark atacks are very dangerous.
Some people that studies the white shark says that the white shark don't like the human blood, and it is useless for them.
The white shark's atack is because:

* The shark does not attack the victim with intention of eating up it, but because heconsiders her to be an intruder in his daily activity which it interprets as a potential threat.

*The animal feels confused before something that it has never seen before and does not know if it is eatable or not. Therefore, the fleeting assault is a species of bite with the one that tries to do an idea to him of if it is convenient for him to feed in the future of this new element in his world.

*The shark confuses the victim with his habitual food. In this case many of the assaults would be explained against bathers and surfistas in California, for example, since when they are seen from below they turn out to be similar enough to a marine lion that goes out to breathe air or that moves full speed near the surface of the water.
