Among the fiercest sharks

The fiercest sharks are whale shark, great white shark, tiger shark, bull shark and great blue shark.

Adult whale sharks are huge, about 20 meters long, and their huge mouths can eat hundreds of pounds of food at a time. Among all sharks, whale sharks have a relatively mild temper, mainly feed on various small fish, usually live in warmer waters, and their distribution areas are not fixed, and they also migrate. Because of their huge size, they usually act alone and rarely appear in groups.

Great white shark, with a body length of 6.5 meters and a weight of 3,200 kilograms, is a very aggressive large shark. Its teeth are as long as 10 cm, and its edges are serrated, which can divide its prey in a very short time. Great white sharks eat a lot of food. Seals, sea lions and other fish are its targets and occasionally eat whale carcasses. Although the great white shark has poor eyesight, it has a good olfactory nerve and is particularly sensitive to the smell of blood. It is also the most famous aggressive shark.

Common characteristics of sharks

The shark's body is long spindle-shaped, the gill splits outward, the pectoral fin is normal and does not heal with the front edge of the snout, the north fin is dorsal and the tail is curved. The body is spindle-shaped with cheeks on both sides of the head, but it is similar to ordinary fish. With a few exceptions, the typical shark skin is hard and dark gray, and the dentate scales make the skin look rough. The tail is strong, asymmetrical and upturned, and the fins are pointed. The nose and mouth are pointed and protruding, the mouth is crescent, and there are triangular fangs under the nose and mouth.

Sharks don't have swim bladders, so they need to swim constantly to avoid sinking into the water. 80% species of sharks are below 1.6m in length, and most sharks are small fish. Among sharks, the largest whale shark is also called Whale Pattern, with a body length of 20m and a weight of 7,000-8,000 kg, which can be described as the king of fish, and the smallest is the wide-tailed small-horned shark (also called small-horned mackerel), the mature male fish 15cm and the female fish's 20cm.
