Secondly, the observation of human beings has produced human cognitive ability. Some biologists dissected the killer whale's head and found that the head shape and structure are very similar to the human brain, and both have relatively highly flexible brains and the same brain area, so killer whales are recognized as animals with higher intelligence all over the world.
Biologists have also found that killer whales can manipulate cognitive abilities and senses, as well as memory, learning and training. Such high intelligence prompted us to have the concept of observing human beings. After having a certain cognitive ability to human beings, I feel that human beings have strong working ability and terrible destructive power, so it is not easy to attack human beings actively. If killer whales are killed in waters, local killer whales will avoid humans. If humans help killer whales in their waters, killer whales will approach humans.
Great white sharks live in coastal areas, and some people who swim by the sea are very likely to meet great white sharks and be attacked by crocodiles. Black whales usually live in remote areas and are unlikely to meet killer whales in deep diving areas. After all, they are so tall that they are unlikely to live on the coast every day. Secondly, the dolphin family, including killer whales and whales, is likely to realize that human beings are also mammals, similar to themselves, so they have a kind of affinity for human beings, and it is not easy to hate or hurt human beings, and it is not easy to regard human beings as their prey. So whether out of curiosity or caution, killer whales are not easy to refuse to attack humans.
Black whales are friendly to humans, but that doesn't mean they are docile. As a relatively large species in the dolphin family, they weigh about nine tons and are very good at attacking. They mainly use their own unique sonar system for foraging. According to the sound frequency of sonar pronunciation, they apply the basic principle of echo to find fish, distinguish the orientation, size and total number of fish, and inform their friends to panic together. The brains of smart people and the cooperation of elite teams are also the reasons why great white sharks are worried about them.
When killer whales recognize great white sharks nearby, they generally don't choose the opposite approach easily, and they can only hunt great white sharks by teamwork. The killer whale first lures the great white shark with its small tail, making the great white shark think that it is also hunting and following the coming sea level. Then, it uses the vortex of upper body strength caused by the whole process of shaking its small tail to let the great white shark enter the vortex, and then hits the top of the great white shark with its small tail heavily. The beaten great white shark cannot be completely ejected like being clicked by others, and can only be used by killer whales. The black whale will bite the great white shark until it dies.
Black whales especially like to eat the liver of great white sharks. Some killer whales can accurately identify the location of the great white shark's liver and accurately bite off a part of the great white shark's pectoral fin. In the case of 20 17, five great white sharks with only dead bodies were found in the new area on the west coast of South Africa, and the killer was probably a killer whale, so it was daunting for the great white shark to target the killer whale. If there are killer whales in this position, the great white shark will generally disappear for no reason.
However, such an intelligent and fierce microorganism is rampant in the ocean and naughty to the extreme, but there is no record of being injured in the wild, and it helps people who fall into the water, so that it is generally felt that natural killer whales are not easy to threaten human safety. However, human beings do not respect this kind of "panda baby" in the sea. Humans raise killer whales and use them to perform, which has won the joy of tourists, but behind them, killer whales have to bear endless destruction and pain.
