SOMETHING ABOUT...

DISTRIBUTION AND HABITAT

The white shark usually lives in waters which have a water temperature between 12 and 30 ºC. The white shark lives in:

The biggest fish

Scientist name: carcharodon carcharias. Description of the animal: Can measure from 4 to 6 meters of length and weight up to 1200 kilograms The back is gray, whereas his low part is of white color, which has given place to his name. His ratchet teeth are sharpened as cleavers, of profile irregular and arranged in his jaw in several rows lightly sloping.

-It is a difficult forget the reputation of the great and majestic white shark. One of the big predators of the ocean, is the shark easier identifiable of the world, thanks to his distinctives and beautifuls colors, his black eyes and his ferocious teeth and jaw, which per decades, so many front pages of magazines have adorned.

-The white shark is one of the sharks that much distribution has, thanks to his,c unusual skill of supporting the temperature of his body higher than that of the environment that him makes a detour, allowing him to survive happily in very cold waters. In spite of the fact that strangly it can be seen in coastal areas, often it runs up with boats of fishing and skin-diving and is known by his curiosity: the white shark lifts often his head on the water and, the most worrying thing for the human beings who are in the water, explores with bites the objects that him are not familiar.

The senses

The white shark has a fusion of the Ear and Tact. This fusion is connected to a few cells that his skin presents principally in the knob and the wings, and that are named cells ciliadas. They allow him to detect among other things the currents and vibrations, to control the direction...

Also there is very marked the sensibility of his smell, capable of detecting the blood to big distances and, unlike what he is in the habit of being thought, his sight. Though he is more prepared to operate in conditions of scanty luminosity, there presents as particularity a membrane so called tapetum that acts like sunlight reflector increasing notably the sensibility of the eye.

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.
