There is an explanation why the great white shark has such an unusual list of food, namely because of its electroreception sense, by which it can easily detect the electric field emitted by its prey. Having this amazing sense, sharks are attracted by the motor boats which generate a great electromagnetic field, making them very curios to grab a bite.
There are still some debates going on in the paleontology department, about the evolution and the ancestor of this great carnivore, some think that the white shark evolved from the broad-toothed Mako shark, others think that it’s related to the Carcharodon Megalodon, known as the largest carnivorous fish which grew up to a length of 18 meters.
Being a homeothermic, it needs a warm habitat to maintain and regulate its body temperature, so you can find a dense population of the great white in the waters of Mediterranean, also in the coasts of Australia, South Africa, New Zeeland, northeastern US and Mexico.
If you are interested in exciting activities there are several companies in Guadalupe Islands, Australia and South Africa that are specialized in cage diving, where you can experience a freighting yet an amazing journey and see more closely this great carnivore.
A trip like this can cost you up to £50 per person and it became a very profitable and popular tourist activity over the past few years.
During the long time between birth and sexual maturity, that takes about 15 years, sharks never reproduce and when they reach the sexual maturity it takes about 11 months for a female to give birth. Being an ovoviviparous, it means that the eggs hatch inside the uterus and evolve until birth; the pups develop their killing skills before birth in uterus of its mother, by eating each other, so that the strongest will survive.
They are considered to be the biggest predatory fish in the world, which feeds on seals, dolphins, sea lions, porpoises, it also in turn became victims of humans, being killed for there fins, jaws, teeth and flesh.
So based on this facts, the great white shark is now considered to be endangered, so in April of 2007 the government of New Zeeland took some cautious to save the population of this amazing predator by fully protecting the area of New Zeeland and inducing fee penalty and prison the fishermen who disobey the law.
