The killer shark species of the ocean

Sharks are considered oceanic killers, one of the most dangerous animals on earth. With strong jaws, sharp teeth, sharks possess the ability to destroy prey in a flash. In addition to white sharks, famous through films of Hollywood, shark family members also have many other members equally dangerous. Let's take a look at the most dangerous sharks in the ocean world through the article below.

White shark

White sharks are another great shark commonly found in coastal areas throughout the oceans. With a length of 6 meters, weighing more than 2 tons, white sharks are the largest carnivorous fish in the world . They are also considered to be top predators when threatened only by humans and killer whales (there have been cases of adult white sharks being eaten by killer whales).

White sharks have bodies that help them swim faster. The white shark's back is light gray. When viewed from the belly of the abdomen they are white and their backs are green. White sharks often swim and hunt during the day. They can swim up to 32km / hour. Their tail has ledges that block the water's power to help the fish launch as a shot.

Because teeth are the most important hunting tool for white sharks, they can change teeth many times. Shark teeth can be changed without restriction throughout their life. As soon as a tooth is broken or damaged . a new one will replace it within a very short time, even in just 24 hours. This feature helps sharks always have strong teeth, ensuring successful hunting.

Cow sharks

Cow sharks are a popular shark in the world, considered to be the most primitive of all sharks because their bones are the least evolutionary compared to other sharks. Live in warm and shallow waters along the coast and rivers, prefer shallow water and often in brackish or freshwater areas including estuaries and rivers. They can live in both sea and fresh water and can live in rivers deep inland. Bull sharks are known for their aggressive behavior.

They were found in Indiana, USA in the Ohio River. They are probably sharks that have attacked humans in near-sea attacks, even in the case of other sharks. Cow sharks are not really freshwater fish although it can live in fresh water unlike a river shark belonging to the genus Glyphis.

Zebra shark

This shark has a distinctive appearance, often lying on the seabed, which can be up to 1.25m long. Although not dangerous to humans, this fish also bites divers if they think they are attacked.

Sharks have crests

Crested sharks are an uncommon bull head shark in the Heterodontidae family, distributed off the east of Australia from the coast to a depth of 93m. This shark species can be distinguished from other members of its family by the large size of the veins on its eyes and the color pattern. It usually reaches 1.2m in length. As a night-dwelling species and living in the water's bottom, appearing in many parts of the Pacific and Atlantic Ocean, this fish prefers rocky reefs and vegetation areas, where it hunts sea urchins and other fish. Other small creatures.

It is an egg-laying species , females lay egg bags that attach to seaweed or sponge with long fringes. Sex matures slowly, with one female in captivity not laying eggs until nearly 12 years old. The International Union for Conservation of Nature (IUCN) has assessed this harmless shark as less of a concern; It is without economic benefits and minimal death due to fishing activities, recreational fishing, and shark nets. Crested sharks have up to 300 teeth, their mouths can swell to allow them to swallow prey by half their body size.

Cookiecutter sharks

This bright shark species is only 17 to 22 inches long, but what they lack in size is compensated with disgust (as well as strange). As you can see, this cigar-shaped shark is wandering in the water, waiting for the larger prey to appear. Their bodies glowed, except for a dark collar behind the head, and people thought this dark part was a shadow of a small fish, acting as a bait.

Although the cookiecutter shark is able to eat a whole squid, its most famous trait is parasite . First, they attach themselves to larger organisms by pressing their sucking lips into the animal's flesh. Once they are attached, this shark bites into the host. The upper teeth act as an anchor, while the lower jaw moves forward like an electric shave. The shark then twists and turns, until it cuts a piece of meat about 2 inches wide and 2.8 inches deep.

In fact, shark cookiecutter ate large and medium-sized creatures that shared the habitat in the tropics. Whales, dolphins, sharks, seals and bone fish have been found to have been injured by them. This frighteningly small monster is also known to bite submarines, underwater cables, and even humans.

Wide mouth shark

From one big mouth shark to another big mouth. Wide mouth sharks are so rare and strange that they have a family name in their classification: Megachasmidae . This soft-bodied fish are slow swimmers, with soft fins and asymmetrical tails. And because they are so rare, very few are known about them.

What we know is that they are filtered species and can be up to 18 feet long. In addition, the wide mouth is surrounded by light-emitting organs (photophore), thought to be used to attract plankton. Wide mouth sharks live deep in the daytime and up close to the surface at night, following their food source.

Amazingly, only 54 times were recorded to detect this fish since the first discovery off Hawaii in 1976, when one was caught in the anchor of the US Navy ship. They are found in the Pacific, Atlantic and Indian Ocean.

The name of this shark is named after its distinctive head. Hammerhead sharks have two eyes placed on either side of ' cephalofoil' - a hammer, which allows them to see both at the top and bottom at the same time. Hammerhead sharks have a very flexible turning ability with high speed. This fish often swim in the herd during the day, and has a strict order of power in the group.

Long-shanked shark

Look at this strange next shark.Longnose sawshark is one of six swordfish species, it can be up to 4 and a half feet long. Long, serrated noses with sharp teeth make up a third of their weight.

Long-nose sword sharks also have long antennae that grow on the sides of the nose - quite like whiskers - and use it to find food. This beard can move completely easily, and they feel vibrations and bioelectricity, similar to how hammerhead fish find their favorite stingray snack. What is even more interesting is that this beard is very sensitive to touch and taste - this makes them perfect when they feel the prey hiding under the sand.

When the long-nosed shark finds its prey, it swings its nose around, injuring it, and even stabs its unfortunate body. The shark had its head very strong until its prey fell out of its multi-toothed nose, and then it sucked the prey into its mouth and chewed with sharp teeth.

This is a fish that lives in deep water, has a shovel-shaped nose that helps them identify food, when needed, their jaws can protrude. Mostly, goblin sharks keep their jaws folded. However, when the prey appears, their jaws will protrude like a clamp.

Most goblin sharks keep their jaws ' folded ' at the level behind their eyes. However, when the prey appeared, its jaw, equipped with razor-sharp teeth, shot forward - a bit like a clamp. At the same time, this shark uses its tongue to suck its prey into its scary mouth.

Another strange and shark-less feature of goblin sharks is the striking pink and blue color. The capillaries are close to the surface of the body emerging from the milky skin, giving them distinctive colors. First discovered by a Japanese fisherman, goblin sharks have been discovered around the world - from Australia to the Gulf of Mexico.

- Shortfin Mako

Short fin Mako sharks are the fastest shark in the country. It has the same speed as the on-land paul press . It must be fast because its prey is tuna is also very fast. Both prey and predator share the same characteristics that the body makes them swim fast.

Short-finned Mako sharks are found throughout tropical and temperate seas around the world. They are distributed from the surface to relatively deep. They are ocean swimmers, but sometimes appear near shore. In warm tropical waters, they swim deep below the water because they like cooler water.

The shortfin mako shark attacks people. Fewer people die than blood loss or no quick medical help. The assault people are usually divers and people who feed it. Makako sharks do not swim near the beaches, so the swimmers and the surfers are not dangerous by this shark.

- Tiger Shark

Tiger sharks are named after vertical stripes, dark colors are found mainly in small sharks. When big tiger sharks, these stripes fade and almost disappear.

They are predatory sharks in the ocean and eat almost anything even metal. This makes them a threat to people. They attack people and many tiger sharks have human bodies in their stomachs. Tiger sharks are blamed for many human deaths because sometimes they swim near the shore to pursue turtles.

Tiger sharks are often found in tropical and subtropical waters around the world.

They have a reputation for cannibalism.
