Sixgill shark is among the largest marine predators of their family. 5.4 meters – the maximum recorded length. The average size of this shark is 3-4 feet. Danger to humans it is not, but negatively related to touch and trying to get away from divers at depth. Despite the apparent slowness and clumsiness, while hunting sixgill shark is able to perform rapid shots for the elusive victim.

5. Tiger shark
The tiger shark is one of the largest marine predators, which belongs to the largest sharks. Although the body size of individuals of this species reaches an average of 5 meters, the researchers suggest that there are larger specimens. Their size can exceed 7 meters. Like white shark, this species is most dangerous to humans. Often in the stomachs of marine predators find parts of human bodies. To protect people from attacks in some countries are shooting tiger sharks.
5. Pelagic largemouth shark
Honorable fifth place in the ranking of the largest sharks in the world is a pelagic largemouth shark. She is also one of the most poorly studied species. This deep-sea dweller was opened rather recently, in 1976. The maximum size of caught specimens were made of 5.70 meters. Scientists have discovered a total of 60 largemouth sharks.
4. White shark
Carcharodon, white shark, often referred to as "shark-killer" impresses not only by the enormous power of their jaws, but also the size. This most dangerous predator of the sea is one of the largest sharks in the world. The average size of individuals of this species reaches 4.5 meters. In the history there were several cases where fishermen caught carcharodon longer than 6 meters. The white shark is an endangered kind in the world there are only 3500 specimens.
3. Bowhead shark
Bowhead shark belongs to the largest sharks in the world live in the Northern waters. Its size can reach 6-7 m and weigh half a ton. Because of its slowness it, according to scientists, applies special tactics while hunting – catches of seals, when they are sleeping peacefully in the water. The polar shark is one of the most sluggish fish on Earth. Its speed does not exceed 2.7 kilometers per hour, due to the low temperature of its habitat.
2. The basking shark
Giant (giant) shark – second place among the largest sharks in the world belongs to this species. Males slightly smaller than females, the size of the latter reaches 9,8 meters. Perhaps there are instances of length up to 15 meters. In the XIX century in the network of fishermen caught specimens with a length of about 12 meters. Due to mass extermination of large specimens are now very rare. Giant shark eats plankton, krill and small fish. Danger to humans is not, although looks menacing, when mouth opens wide. The basking shark allows the divers to come at a close distance. But touch it not necessary because of the sharp scales that can injure the skin.
1. The whale shark
Whale shark – the palm size should be given. He is one of the largest sharks in the world, and the largest of the modern fish. The average body length of the whale shark reaches 12-14 meters, but it is possible that there are individual members of a species larger and 18-20 meters in length. To eat this gigantic sea dweller struggle every day to absorb approximately 200 pounds of plankton and small fish. The largest recorded weight of the whale shark was 36 tons.
If we consider the extinct species, here the undisputed winner in the ranking of the largest sharks in the world Megalodon is. Fossil remains suggest that he has reached at least 16 feet in length and can weigh about 50 tons. Ate this superhilac cetaceans and large fish. Was widespread and, due to its size, the enemies had.
