Great white shark is one of the most widely distributed sharks, because it has an unusual ability to keep its body temperature higher than the ambient temperature, which enables it to live comfortably in very cold sea water. Although it is hard to see in most coastal areas, fishing boats and diving boats often meet unexpectedly. Great white shark is an oviparous great white shark, and it is also famous for its curiosity-it often looks up from the water, and what worries people in the water is that it often explores unfamiliar targets by biting. Many shark biologists believe that the attack on humans is the result of this exploration. Because of the incredible sharp teeth and jaw strength of great white sharks, it is likely to easily lead to human death. Great white sharks have caused the greatest number of deadly attacks on human beings, especially surfers and divers. Great white sharks have an extremely sensitive sense of smell and touch. It can smell the blood diluted to the original concentration at a distance of 1/500 km and drive away at a speed of more than 40km/h, and can also detect the tiny current generated by the contraction of biological muscles to judge the size and movement of prey. There is an unconfirmed speculation that this creature is extremely sensitive and can even perceive the emotions of other creatures and perceive them. We humans only change our teeth when we are young, and it is impossible to change our teeth when we grow up. And even if it is replaced in hours, it will fall off before, and then new teeth will slowly grow on the gums. However, great white sharks are very different from humans in this respect. In its maw, there are 26 sharp teeth on the upper jaw, and there are barbs behind the teeth, so it is difficult for the prey to break free after being bitten. Once any tooth in front of the great white shark falls off, the extra teeth in the back will move to the front to supplement it. At any time, about one-third of the teeth of great white sharks are in the process of replacement. It is estimated that great white sharks will lose and replace thousands of teeth in their lifetime. If the teeth of the great white shark can be sold for money, then the great white shark must be a multimillionaire. Think about it, it would be great if we humans had such skills, but in that case, dentists and stomatological hospitals may lose their jobs or close down. Not only the teeth, but also the skin of the great white shark is deadly. "Shark skin" is not smooth. Although there are no fish scales, they are covered with small barbs, which are rougher than sandpaper. Even if the prey is hit by it, it will bleed profusely. Great white sharks will swallow everything they are interested in: meat, bones, wood blocks, even pens and glass bottles. Their stomachs have a hard wall, so what they swallow won't hurt them. The number of great white sharks is decreasing, and now many parts of the world are protecting it. Nevertheless, they are still victims of regular hunting, and there are transactions related to the teeth and jaws of these strong animals on the black market. Maximum size: above 6.4m/2500kg. Distribution: anywhere in the temperate and tropical oceans of the world. Have you ever seen a fish stand its head on the water? Among all sharks, the great white shark is the only one that can stand upright on the water, which gives them the advantage of finding potential prey on the water. However, great white sharks usually attack underwater. It will accelerate from under the seal and hit the water. Its huge body can even jump out of the air completely and bite the poor seal.
