Why is the great white shark, which has never been an enemy of marine animals, now listed as an endangered animal by the World Conservation Organization?

Because the great white shark is an essential link in the marine biological chain, it plays a role in controlling the number of some mammals in the ocean, eating the old, the weak and the sick, and promoting survival and competition. In addition, great white sharks will devour the dead animals in the ocean and clean the ocean. Unfortunately, the elegant great white shark has been misunderstood by humans and killed in large numbers, and its number has dropped sharply, so it has now been listed as an endangered animal by the World Animal Protection Organization.

There are about 350 kinds of sharks living in the ocean in the world. It has lived on our planet for over 300 million years. Among all sharks, the great white shark is the biggest, fiercest and most energetic. No marine animal dares to be an enemy of the great white shark.

Biologists believe that great white sharks can grow to 7.6 1 m long and live for 20 years. The newborn baby great white shark is about 1.06 meters, and will hunt by itself on the day of birth. The female great white shark is 4.84m long and weighs 1360-272 1 kg. Fishermen sometimes find nothing, because their nets are smashed and torn by fierce great white sharks.

Great white sharks are typical carnivores. Young great white sharks prey on fish. When they grow to 2.74-3.65 meters, they turn to mammals such as seals and sea lions, which are bigger than fish in the ocean. When hunting, great white sharks often swim slowly around their prey; Then quietly sink to the bottom of the sea and hide your body between rocks. At the right time, it suddenly pounced on the abdomen or tail of its prey like lightning, and its blade-like teeth bit the prey into several pieces and swallowed it in three bites.

Great white sharks are covered with rows of sharp scales called dermal teeth. Each fish scale is like a tiny tooth, and the surface of the fish skin is as hard as sandpaper. If a great white shark swimming at high speed comes into contact with human body, human skin will be cut.
