Everyone knows that sharks are the most important animals in the ocean, and among sharks, the most terrifying is the great white shark. Great white sharks have a white complexion, one.

The head is large, generally about 7-8 meters, and the large can reach 12 meters. Like other sharks, it has a very keen sense of smell and can smell it from up to a kilometer away.

The tiny smell of blood in the sea. Therefore, once humans and marine animals are injured in the water, they can attract shark attacks and deaths.

Scientists have experimented that sharks bite no more than humans. But its teeth are very powerful, and each tooth has small dramatic teeth on the tooth blade, and these teeth are arranged in rows in the mouth, up to 7 rows, there are as many as 10,000! In addition, they are constantly replacing new teeth to keep them sharp.

The great white shark also has tooth-like protruding scales on it, and each row of scales resembles a row of sharp knives, which will tear even if you rub it on other animals.

Lose large pieces of flesh and skin. According to scientists, this body has the effect of filtering out the water flow and reducing the resistance of the shark in the water. Thus, scientists based on this.

principle, which put a layer on the shell of the submarine"Scales"to increase the speed of travel of the submarine. Due to the small number of great white sharks, they are large and have a fierce temperament.

Fierce, infested and impermanent, it is difficult to detect and capture, therefore, there are still some unsolved mysteries. Plus the legend of the great white shark ** killing, and give it even more.

Spice it up with a layer of mystery.

First of all, there is the reproductive process of the great white shark. When the female shark reaches sexual maturity, it is about 5 meters old and difficult to catch. Therefore, to this day people still have not.

A pregnant female shark can be examined closely, let alone observed during her reproduction.

Secondly, because the great white shark prefers to move alone, its population has not yet been known. Also, why would great white sharks attack people, on this.

Opinions differ. Some scientists believe that the attack on humans by great white sharks is a pure error of judgment, and they treat the person who falls into the water as their favorite seal.

Sea lions. Some scientists believe that the bite of great white sharks is a warning to those who intrude on their territory. Some scholars believe that the great white shark's attack on people may be caused by a disturbance of some balance mechanism in its body.

There are still some mysteries to be unraveled. For example, why are the fierce great white sharks most afraid of orange and yellow? Just put a yellow plank on the great white shark.

around, it will quickly swim away? As the number of great white sharks continues to decline, it is more difficult to uncover the secrets, so scientists have raised the issue to humans.

Warnings were issued to protect them from extinction.

Are sharks really that scary? Do sharks really eat people.

The natural predator of sharks is killer whales.

Killer whales, a large toothed whale, are dolphins and can be regarded as a kind of whale and a kind of dolphin in principle. Among them, Atlantic type 2 and Antarctic type A killer whales take cetaceans and even blue whales as their main food, and pelagic killer whales use sharks as their main food, which is a well-deserved overlord of the sea. It can reach a length of 8-10 meters, weighs about 9 tons, has a slightly rounded head and an inconspicuous beak.

dorsal fin tall and erect, curved up to 1 m; The body is black and white. The wings are far apart. The temporal fossa is large.

The mandible is comparatively shorter. There are 10-12 conical teeth per dentition in the upper and lower jaws. It has a slender mouth, sharp teeth, and a fierce temperament, and is good at attacking its prey.

Killer whales can live up to 80-90 years in the wild, but the average lifespan is only 20-30 years in human captivity. The killer whale is an extremely intelligent animal, no less emotionally rich than primates, has a strong language system, has very few dialects in animals, and even uses its tone to taunt its own kind that fails to hunt, and has a high degree of sociality.

Killer whales are highly social animals, with some groups of families that are the most stable in the animal kingdom. Some of the complex social behaviors, hunting techniques, and vocal communication of killer whales are considered evidence that killer whales have their own culture. It is found in almost all ocean areas, from the equator to the polar waters.

There is no limit to its range by water temperature or depth.

Killer whales are not threatened with extinction, but human hunting may have caused population declines in some areas. Killer whales in Washington state and British Columbia, with only a few hundred remaining in both the sedentary and transiting states, are threatened by pollution, heavy boating, and dwindling prey.

Intensive whale watching can interfere with killer whales, and those trying to protect salmon farms from pinnipeds and dwindling prey threats. Intensive whale watching activities can invade people and expel killer whales from their preferred habitats.

It is estimated that there are about 8,500 killer whales in the tropical waters of the eastern Pacific Ocean, at least 850 in Alaskan waters, more than 2,000 off the coast of Japan, and about 8,000 in Antarctic waters in summer, with other areas of the range possibly between hundreds and thousands.

Killer whales continue to be caught by whalers in Japan, Indonesia, Greenland, and the West Indies, and although the catches are small, they can have a considerable impact on local populations.

The three most feared sharks in the world are the great white shark, the tiger shark and the bull shark. These three sharks can be described as the kings of the ocean, and no creature in the ocean dares to match these three sharks, they are invincible in the ocean.

1. Great white shark:

The great white shark is one of the top ten dangerous animals in the world and is the most terrible of the three terrible sharks, and the great white shark is also the only shark in the whole world that can attack humans.

However, only the great white shark is a creature that is particularly bold and dares to argue with humans, many great white sharks have invaded the inland sea areas of many countries, killing fishermen in many countries, and the great white shark has suffered a very heavy price, but this can not shake the status of the great white shark in the shark.

2. Tiger shark: The combat effectiveness of the tiger shark is comparable to that of the great white shark, but the tiger shark is a very gentle shark, the tiger shark usually takes humans as friends, and has never thought of taking the initiative to attack humans, but the tiger shark bullies those small fish and shrimp under the seabed, usually some small fish and shrimp with moderate size, including squid, are tiger sharks' dishes, tiger sharks' sharp teeth make many underwater creatures very afraid, even crustacean tiger sharks can bite them apart.

3. Bull shark: The bull shark is very strong like the cattle on land, so it is named the bull shark, the bull shark is a very strong shark with a very strong appearance, able to fight with all creatures on the bottom of the sea, although the length of the bull shark is only about three meters, but this does not affect it to fight against the tiger shark, if the tiger shark does not have sharp teeth, I am afraid it will be defeated under the attack of the bull shark.

In addition, the bull shark is also a particularly peculiar shark, most sharks can only be suitable for survival on the bottom of the sea, but the bull shark can not only be suitable for survival on the bottom of the sea, but also suitable for ordinary freshwater lake survival, so the bull shark has a very strong vitality, and is also very friendly with humans, and does not dare to attack humans easily.

Sharks are most afraid of killer whales, which are apex carnivores that no other animal can hunt except humans.

It is a creature that can turn these so-called hunters into hunted people and frighten them to a great extent. Scientists speculate that killer whales have by far the strongest bite force in the animal kingdom, reaching up to 19,000 pounds square inch.

If a great white shark encounters an orca (another name for killer whale), the shark leaves the area immediately and does not return for a year. Scientists observed that whenever killer whales appeared, they did not see a single shark and no more sharks were killed. So orcas are sharks' worst nightmare and probably apex predators of underwater creatures.

Shark Habits:

Sharks mostly feed on marine animals such as late cave fish. Sharks feed on injured marine mammals, fish, and carrion, culling weaker members of the animal. Sharks also eat litter and other waste left behind by boats.

In addition, some sharks also hunt a variety of marine mammals, fish, and animals such as turtles and crabs.

Some sharks can go months without feeding, and the great white shark is one of them. It is reported that the great white shark is going to be separated.

Eat only once in a month or two. <>
