PRECONCEIVED IDEAS
Certain falsehoods concerning Sharks
Hunger does not exist in sharks. This is untrue. "The shark is capable of very long periods of fasting, and it seems that it may have periodicity in its eating habits. During these "eating phases" it is evident that we can talk of "hunger", and attacks then will be different in their determination and development." (Reader's Digest 91)
The shark have a very poor eyesight. Not only can a shark see contrasts well, but it has good night vision thanks to a histological structure peculiar to nocturnal animals. It can even see colors.
Sharks attack in order to feed. The image of the insatiable shark that swallows everything it encounters in order to assuage a hunger that is never satisfied is one of the most false. Over 1500 cases of shark attacks on on men ,50-75% of these attacks have nothing to do with nutrition.
