The biggest shark in the world: as it is called and it looks like it weighs

Sharks are very ancient and widespread representatives of the marine fauna (526 species). These cartilaginous fish with a torpedo-shaped body appeared more than 400 million years ago.

With few exceptions, they belong to real predators and live in sea water. However, the 3 largest sharks in the world – the big-mouthed, the giant and the whale – feed on plankton and other trifles.

The shark lives in the seas and belongs to the predatory species of fish.

The skeleton of sharks has no bones and consists of connective tissue, so they are called cartilaginous fishes. The skin is covered with scales, consisting of small teeth, and resembles sandpaper. The tail fins are arranged vertically, depending on the habitat may have a different shape.

The jaws are equipped with conical teeth, which are constantly growing and, if necessary, replaced.

If there is a breakdown in the connections between the central nervous system and the muscles, they are able to function autonomously.

Low metabolism and primitive structure of the body have led to the fact that sharks do not withstand prolonged loads, because of which they can die. They breathe with the help of gills, constantly passing water through special slots.

The swim bladder of these fish is absent, and the ability to swim perfectly is ensured by a very large liver.

Well developed sense of smell helps to find prey and mating partners. Particularly well distinguished odors one of the largest sharks in the world – hammerhead.

She can smell blood in a concentration of one in a million.

Gestation of offspring in cartilaginous fish occurs in utero. In viviparous species, cubs are born fully formed and ready for independent living.

Pregnancy lasts from several months to 2 years.

The longest shark in the world is the whale, it reaches 20 meters, and the smallest – dwarf prickly, which grows a little more than 25 centimeters. The average speed of movement is 8 km / h, but with acceleration it can reach 20 or even 50 km / h.

The largest shark in the world was called whale due to its size. The average length of this monster is 12 meters, and the maximum is 18-20 m. It weighs about 12 tons, however, there are cases of catching twenty tonnes specimens.

The whale shark is the longest shark in the world

The habitat of the whale shark is tropical latitudes of the world’s oceans. It swims slowly (5 km / h) and does not sink to the depth. Not a real predator and safe for humans.

It feeds on plankton, small fish and shrimps, filtering food from water passed through a special apparatus.

Usually you can meet small groups of sharks, consisting of several individuals. In regions with a large amount of food, fish can stray into large flocks.

In search of plankton they make long-distance migrations.

Today, this unique species has been little studied. It is not known exactly what the largest shark in the world leads a way of life.

The breeding pattern and population size also remains a mystery. In 2016, the largest of the existing fish was declared an endangered species, so most countries have banned its catch.

You can see how the largest shark in the world looks like by visiting the Japanese Churaumi aquarium located on the island of Okinawa. It contains a 7-meter male – the largest specimen living in captivity.

Sharks are quite diverse, many of them reach large sizes. The ranking presents the largest cartilaginous fishes on planet Earth.

Top 10:

  1. Whale. Undoubtedly, she is the leader (first place).
  2. Giant. Has a length of about 10 meters and weighs up to 4 tons. A feature of this giant shark is a very large mouth and gill slits. It feeds on plankton and marine trifles, swimming with open mouth. In an hour, 2 thousand tons of water passes through the fish filtering apparatus. Despite the awesome view, for people it is not dangerous. Due to the decline in the population, it is currently classified as an endangered species.

The giant shark in length reaches 10 meters

  • Greenland Polar Shark. It reaches a length of 7 meters and weighs one and a half tons. It inhabits the cold waters of the Arctic Ocean and the North Atlantic zone. It has a long head, which is a quarter of the whole body. It has a record lifespan among vertebrates – about 300 years. It feeds on live and dead fish.
  • White. Reaches 5−7 meters, with females usually larger than males. Lives around the world ocean and is the largest predatory fish. She gained fame as a cannibal because of the frequent attacks on swimmers and even on boats. The belly is painted white, and the back and sides are gray, which is very beneficial in terms of camouflage.
  • Pelagic bigmouth. It was opened in 1976, but still little studied. To date, 102 representatives of this species have been found. The largest fish caught was 5.7 m long. This is one of 3 sharks feeding on plankton.
  • Tiger (leopard). The most common type of shark. The individual has a length of 5.5 m. It lives in warm waters, and is especially common near the islands of the Pacific Ocean. For a person is a great danger. Brindle color is typical at an early age, with growing sharks with a length of more than 2 meters, the stripes grow dull.
  • Tiger shark is a great danger to humans

  • Giant hammerhead shark. Differs in the original shape of the head and reaches a length of 5 meters. Predator is potentially dangerous to humans. Leads a solitary lifestyle and is common in tropical waters.
  • Sea fox. It is called so because of its tail, which is half the size of the body. The overall size of this unusual shark is 5–6 meters. The elongated upper part of the caudal fin is used as a weapon to defeat prey. They prefer to live in the open ocean at half a kilometer depth. There were no cases of attacks on humans.
  • Hexhaber. Lives in coastal waters, but can descend to a depth of 2.5 km. Distributed in the tropics and subtropics. The maximum length is 5.4 m, the average is about 4 m. It is not dangerous for humans, it is a commercial fish.
  • Mako. Pretty aggressive look. The babies in the womb begin to eat their brothers as soon as they get their teeth. Adult sharks have a body length of 3 to 4.5 m and are distinguished by an incredible speed of movement reaching 70 km / h. Cases of attacks on people and small boats have been recorded.

    The image of a ruthless killer car scouring the expanses of the ocean in search of the smell of blood firmly established behind the shark. She tracks down lonely swimmers and surfers, ready to eat human flesh with pleasure. Artworks, including films that gave rise to common misconceptions, are guilty of creating such fame:

    1. Shark gills are arranged in such a way that it cannot breathe if it lies or stands still. Many individuals can easily pump their own water, resting on the bottom.
    2. Sharks feed on humans and often attack them. Man is not the usual food for these fish. Attacks are only a few kinds, as a rule, this happens by mistake. The victim usually dies from blood loss or drowns, but is not eaten.

    Most shark species do not attack a person intentionally.

  • Huge speed. Sharks are capable of fast jerks and lightning speed in pursuit of prey. The usual speed of movement is small, does not exceed 8 km / h. With prolonged accelerated movement, the individual can quickly die.
  • Hypersensitivity to human blood. Cartilaginous fish from a long distance feel any blood, but they do not distinguish whose it is.
  • Omnivorous. Each species has its own favorite food, which is better to wait than rush for everything.
  • Lack of cancer. This misconception was not confirmed during long-term observation of sharks. They are prone to cancer, and especially in polluted water.
