Whales are a kind of higher intelligence animals, they have more accurate judgment of food, usually will not take the initiative to attack human beings. Whales are divided into baleen whales and toothed whales, baleen whales do not have teeth and are not interested in animals like humans and will not hurt people. Toothed whales are carnivorous predators, but they don't take people as food either. The largest and most ferocious of the toothed whales, the sperm whale, has long been considered the most desirable prey for whalers and has been hunted in large numbers, and there is indeed a historical record of sperm whales biting people in the course of whaling, with quite a number of whalers killed in the mouths of the whales. Except for this special case, no cetaceans will actively attack humans.
