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 up to 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 great 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 within 24 hours. It is this feature that helps the shark always have a strong set of teeth, ensuring successful hunting.
2. Tiger shark
Tiger shark, also known as flower shark, leopard shark is the only species of 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.
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.
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.
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 Gulf to South Carolina. Some other breeding grounds for sand sharks are in Boncuk Bay in Marmaris, Turkey.
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 usually swims in schools during the day, and has a tight order of authority in the school.
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.
