Although killer whales are called "whales", they actually belong to the dolphin family. They are authentic dolphins and the largest dolphins. Adult killer whales can be as long as 10 meter and weigh 9 tons, which is equivalent to the size of a whale. Humans are very small before them.

Black whales are very magical creatures. Their IQ is very high, equivalent to human 15 years old, and they have extremely superb capture skills. Basically, a group of killer whales can dominate the ocean, and all the creatures in the ocean can enter their recipes.

But at the same time, killer whales are also the most picky eaters. Every killer whale population will have its own recipe, and every killer whale will strictly abide by it. For example, after catching a sperm whale, some killer whales only eat each other's chin and nothing else, because their ancestors may only tell them that the sperm whale's chin is delicious.

Scientists have given different explanations. Some people think that killer whales may find human flesh hard to swallow, which is beyond the scope of recipes. Some people think that killer whales recognize the general appearance of an object through sonar, but in the eyes of killer whales, human beings may be a mutated and weak species and should be protected.
