Of the seven species of death sharks, the great white shark attacks humans the most

The most dangerous sharks in the ocean

1. Great white shark

Also known by other names such as white needlepoint, white death, great white shark, great white shark of the order Mackerel, found in coastal areas throughout the oceans. Great white sharks are famous for their size, they can grow up to 6.4 m.

This species is commonly found in coastal areas throughout all oceans. With a weight of more than 2 tons, the great white shark is the largest carnivorous fish in the world. They are also considered top predators when only threatened by humans and killer whales (there have been cases of adult great white sharks being eaten by killer whales).

Because the teeth are the most important hunting tools of great white sharks, they can change teeth many times. Shark teeth can change indefinitely throughout their life. As soon as a tooth is broken, damaged. a new one will replace it within a very short time, even in just 24 hours. It is this feature that helps sharks always have a strong set of teeth, ensuring successful hunting.

According to incomplete statistics, of the 100 shark attacks on humans every year in the world, one-third to one-half of them are caused by great white sharks. In fact, when great white sharks are feeding, it is difficult for them to distinguish between surfers and seals, leading to accidental attacks on humans. They are ferocious marine carnivores and can swim up to 40 km/h. The main food of this predator includes: turtles, seals, dolphins, .

2. Tiger shark

Tiger shark, also known as flower shark, leopard shark is the only shark in the genus Mink shark, family White-eyed shark. This fish lives in tropical and temperate oceans around the world, especially around the central Pacific islands. They seem to eat everything, including humans.

Sometimes people find in their digestive tracts human waste such as license plates or pieces of old tires. This species is notoriously dangerous for attacking swimmers, divers and windsurfers in Hawaii; and they are often called "the scourge of Hawaiian surfers" and "the trash can of the sea".

A study once found the remains of goats, horses, and even metal and garbage in the stomachs of tiger sharks.

The tiger shark's name comes from the black stripes on its body during infancy, but these stripes fade with age. This shark can be more than 4 meters long, with females slightly larger than males. The maximum weight of a female tiger shark can reach 900. Kg. This species is second only to the great white shark in shark attacks on humans. Tiger sharks feed mainly at night, they are also known as "the trash of the sea".

3. Bull shark

The bull shark is a widespread species of shark in the world, considered the most primitive of all sharks because their bones are the least evolved compared to other sharks.

They live in warm, shallow waters along coasts and coriander rivers, prefer shallow water and are common in brackish or freshwater areas, such as estuaries and large rivers. They can live in both seawater and fresh water and can live in rivers deep inland. Bull sharks are known for their aggressive nature.

Although they can survive in rivers, bull sharks are not really freshwater fish.

Bull sharks are commonly found on the east coast of the United States and the Gulf of Mexico, they are extremely aggressive and can even swim into fresh water near the sea, making them more accessible to humans. Adult bull sharks have no natural enemies, they are carnivores and their main foods include: fish, other sharks, turtles, seabirds, rays, dolphins,.

4. Blackfin Shark

This fish usually lives in bays, in coral reefs, where the water is shallow, at depths of 20–75 m. Blackfin shark has a maximum size of about 4m, weighs about 30 kg; Newborn baby shark weighs about 0.7 kg, about 35 cm long. Their main food is small fish, shrimp, crabs, sea snakes.

Blackfin sharks have a very small range and exhibit long-term attachment habits, being able to stay in one place for many years. They are active predators, hunting small bony fish, cephalopods and crustaceans, but also eating sea snakes and seabirds. Behavioral descriptions of blackfin sharks are generally variable and often contradictory, partly reflecting geographic differences within the species.

Blackhead sharks are found in the Gulf of Mexico all year round and they are also one of the sharks that often jump out of the water to feed. When threatened, they will rush to the threatened area, or turn abruptly, roll from side to side, and prepare for a side attack at any moment. Blackhead sharks do not pose a major threat to humans, and although the United States has recorded more than 40 attacks on humans, no deaths have been reported.

5. Sand Shark

The sand shark or brown shark is a subspecies of the Requiem shark in the family Carcharhinidae, native to the Atlantic and Indo-Pacific oceans. They are one of the largest coastal sharks in the world, featuring a large triangular and brown dorsal fin.

True to its name, they are found on sandy bottoms in shallow coastal waters in bays, estuaries, harbors, and estuaries, but it also swims in deeper waters over 200 meters. Sand sharks are found from tropical to temperate seas worldwide, occurring along the Atlantic coast from North America to South America.

Juveniles are commonly found in shallow seas such as the Chesapeake Bay, from the Delaware Bay to South Carolina. Some other sand shark breeding areas are in Boncuk Bay in Marmaris, Turkey.

Sand sharks are often seen near the seafloor, and sometimes in shallow water, where they are seen by surfers. Sand sharks are very unique in their hunting habits, they breathe from the surface, increasing their buoyancy, allowing them to lie almost completely still and approach their prey undetected. Although humans are not their usual prey, US statistics show that sand sharks have attacked more than 30 people, but no one was killed.

6. Hammer Shark

This shark is named after its distinctive head shape. Hammerhead sharks have two eyes located on either side of the "cephalofoil", which allows them to see both above and below at the same time. Hammerhead sharks have the ability to rotate very flexibly at high speeds. This fish often swims in schools during the day, and has a tight order of authority in the school.

There are nine species of hammerhead sharks on Earth, the largest of which is the grooveless hammerhead, known for its small mouth and eyes on the sides of its head. Hammerhead sharks have fewer natural predators and are rarely killed by other marine species as adults, but killer whales remain one of the threats to their survival. There have been cases of hammerhead sharks attacking people in the past, but they were not fatal, instead they were often just curious for divers.

7. Shortfin mako shark

The shortfin mako shark is a species of large shark in the family Lamnidae. It and its close relative, the longfin mako shark, are collectively known as the mako shark. Shortfin mako sharks are found in temperate and tropical seas around the world.

In addition to some individuals achieving swimming speeds of up to 74 km / h, they can also jump up to 6 m high out of the water.

This is one of the most dangerous sharks in the ocean, its bite force is very strong among sharks, reaching 610 kg, usually most prey does not have a chance to escape when hunted by them. chase. According to the report, to date, there have been 9 recorded cases of shortfin mako shark attacks on humans, of which 1 resulted in death.
