Sharks, which you would not like to meet even in my dreams

Sharks, probably the most popular, interesting, mysterious and dangerous at the same time a kind of fish. They appeared on our planet before the dinosaurs and has reached a fantastic variety of types, shapes and sizes. And if some of them look completely ordinary and safe shallow sea predators, others inspire horror by its appearance, eliminating any desire to be near them.

The worst shark You ever wanted to meet

White shark (lat. Carcharodon carcharias)

This hero of many blockbusters, better known as the “great white shark” (direct tracing-paper with English names), is considered the most dangerous to human form of sea predators, it is often called a killer shark or man — eater, and therefore was, perhaps, the best known of all species of predatory fish on the planet.

The white shark is the top of the food pyramid: in adults of this predator has no natural enemies. White shark — the biggest shark species and in some cases up to 6 meters in length. Only young sharks can fall victim to other major water hunters, estuarine crocodiles and killer whales. However, despite all these circumstances and the reputation of bloodthirsty killers divers, man is not the most desirable food of this shark and from 1990 to 2011 reported a total of 140 confirmed napadeniya shark.

The frilled shark (lat. Chlamydoselachus anguineus)

This shark’s appearance is rather like a Moray eel, sea snake or the creation of artist Hans Rudolf Giger, the author’s characters in “Alien” and “Species”. Frill-neck shark . caught off the coast of Japan, was first described in the late 19th century and got its name due to the wide skin folds in the Gill slits.

The movable jaw of these sharks is dotted with “bundles” hook prehensile teeth, which do not allow trapped victims to escape. The basis of the power of these unusual predators are deep-sea squid, also in the diet includes fish and other sharks. Fortunately, this species does not exceed 2 meters in length and most of life spent in the vast depths, eliminating a real danger to humans.

Australian bull shark (lat. Heterodontus portusjacksoni)

Despite the similarity in name, this shark is a very distant relative of the bull shark (bull shark) and is found only off the coast of Australia. Its appearance is both funny and uncomfortable: the head looks like the head of a cow or a dinosaur and jaw have a very unusual form associated with echinoderms and other eating solid food. Because this type has dimensions in the range of 1.6 m and quite tenacious in cramped conditions, the Australian sharks have become to some extent popular aquarium fish in the United States. It is interesting that sharks, even quite large, usually live in aquariums with other fish species, so why do harmless small fish survive in such close proximity to a predator, like a shark? The fact is that hunting is only a hungry shark . and because the metabolism of these fish is quite slow, the food shark is required no more than once every few days, and during this time other fish can feel safe, if, of course, caretaker of the aquarium will be in time to feed the predator. In addition, sharks in aquariums feeding already dead prey, and the predators lost the desire to further “strain” to chase live fish.

Pelagic largemouth shark (lat. Megachasma pelagios)

Despite the impressive size (the largest measured instance is 5.7 meters), this species was described relatively recently – in 1983. To this day largemouth shark remains very little studied due to its rarity and habitats at depths up to several kilometers.

Pelagic largemouth shark along with the whale and basking shark, is one of three known species of sharks that feed on plankton. A giant mouth that shark constantly opens for respiration and nutrition, despite the terrifying, does not represent a real danger for divers. However, being close to this giant, it’s hard to convince yourself that the neighborhood is completely safe.

Tiger shark (lat. Galeocerdo cuvier)

Along with this white shark is a large species of marine predators is one of the most dangerous to humans, to 2011 year there were 169 attacks on humans. In the stomachs of sharks caught repeatedly found fragments of human bodies. In connection with a specific reputation of this kind during the second half of the 20th century tiger sharks were killed EN masse in order to improve the situation in the tourism industry, however, confirmed evidence of benefit from these actions.

Despite the fact that in the statistics of the attacks, a significant share falls on tiger sharks, the danger of this view is exaggerated, because in the waters of the coastal habitat of this mass of sharks every year swim thousands of people, and attacks are calculated per year. However, 30 attacks a tiger shark in history was over all ended fatally.

Shark-house (lat. Mitsukurina owstoni)

This shark, better known under the English name of the shark-Goblin, was first produced in 1897, but a long time to identify it accurately was not possible due to the fact that shark’s jaw can far to move, drastically changing the head of a predator. Different individuals fell into the hands of people with different condition of the jaws, which had seriously hampered the detection of the species. Another feature of this monster is the pink color body that is associated with visible through the translucent skin blood vessels. After death, however, the body takes a brown color.

The largest of the instances of shark-house amounted to nearly 4 meters in length and weighed 210 pounds. Given the presence of large prehensile teeth, the encounter with this shark may face not only problems with nightmares, but also serious injuries. However, the rarity and the depth habitat of this monster virtually eliminates real meeting with a man.
