The hammer fish, belonging to the detachment of Karharine-shaped sharks, has long been used by sailors for unkind fame. And it cannot be said that this predatory fish was more dangerous than other sharks. The white shark is much more gluttonous, more active, meaner, after all, than a hammer fish. No, the latter also eats everything that moves, and he will eat a person if he gets a tooth, but she is far from a white shark and many other brothers by zoological classification.

Who says that in the hierarchy of danger, the hammer-fish occupies the third place (letting go even the tiger shark), who claims that it is even more peaceful.

Why is a hammer fish considered so sinister? First of all, due to the fact that she is always paid more attention due to the unusual shape of the head. It was the silhouette of this shark, resembling a hammer with a handle, and gave it a name. The predator, of course, looks spectacular, therefore, the hammer fish, the photo of which adorn many exhibition stands, is one of the symbols of the ocean. Photos of sharks in general look advantageous: strong, agile, ruthless predators will not leave anyone indifferent.

There is little news of the attack of this shark on humans, but the starving hammerfish is very dangerous. This six-meter predator has sharp teeth, and in the process of evolution acquired the qualities of a born killer. True, in ordinary, not extreme conditions, it feeds mainly on fish and shellfish. There is a known case when a rather large stingray was found in her stomach, and once even (but this is absolutely from the area of ​​sea tales) and a person - a shark supposedly swallowed it whole!

A hammer fish is viviparous, and in one sitting it can produce up to fifty small hammers. The fish live in schools, however, small in numbers. In search of food, they constantly wander, swimming back to where the food smells.

The eyes of the shark are located on the edges of the hammer-shaped head, and theoretically, the area immediately in front of its nose is a “dead zone” that the shark simply does not see. But to check first-hand whether this is actually so is not recommended to anyone. Indeed, a hammer fish, like any shark, is oriented in the water column mainly by smell and sound, and vision plays only an auxiliary role. And then, it’s worth the shark to at least slightly change the position of the head (turn to the side, for example), as the “dead zone” will become such for the experimenter in the most literal sense.

Why is the fish such an unusual head shape? This question has long tormented zoologists. The answer to it was found recently. It turned out that a flat hammer-shaped head is a natural electromagnetic locator, and such an unusual shape is needed for its effective work - scanning the surrounding space in search of food.

It is possible that a shark needs such a head to use it as an additional fin. It is no secret that hammerhead fish are much more mobile and maneuverable in water than other sharks. It is such a perfect organism that it could quickly proliferate in huge quantities, if not for the person who catches this predator, regulating its number.

As the saying goes, not all cats have Shrovetide, and a predator eating everything around itself often becomes food itself. According to gourmets, the fin fish soup is an unearthly delicacy. The meat, they say, is also tasty, but it’s far from the fin soup - both in terms of gastronomic achievements and in terms of price.
