Some people say that it is because humans are not in the diet of killer whales, but if you put mammals such as pigs and sheep that you have never seen before into the sea, killer whales will still be killed.
At present, the theory of human sea apes can be reasonably explained. Sea apes, the ancestors of terrestrial humans, have a long history of mutually beneficial cooperation with dolphins and other creatures, and the benefits even far exceed those of the same kind (there are attacks between killer whales), so this kind of marine creatures are deeply branded with the attitude of being close to the people in their genes (similar to selling cute wild cats, it is easier to survive).
Killer whales passing by in the North Atlantic and AB killer whales in the South Pole feed on marine mammals and other whales. If humans and these killer whales exist in the same environment for a long time, I believe they will be included in their diet.
Extended data:
Orcinus orca is a large toothed whale and dolphin, which can be regarded as whales and dolphins in principle.
Among them, Atlantic 2 killer whales and Antarctic A killer whales take whales or even blue whales as their main food, while marine killer whales take sharks as their main food, so they are well-deserved overlords in the sea. The body length can reach 8- 10 meters, and the weight is about 9 tons. The head is slightly round and the beak is not obvious. The dorsal fin is tall and upright, with a bending length of 1 m; The body is black and white. The wings are far apart.
The temporal fossa is very large. The mandible is relatively short. There are 10- 12 conical teeth in each dentition of maxilla and maxilla. Long and thin mouth, sharp teeth, fierce temperament, good at attacking prey.
The life span of killer whales in the wild can reach 80-90 years, but the average life span of human captivity is only 20-30 years.
Black whale is a high IQ animal, as emotional as primates. They have a strong language system, few dialects in animals, and even use tones to ridicule their partners who have failed to hunt. They are highly social. Black whales imprisoned for a long time without their parents or children will suffer from mental diseases other than physical diseases, such as depression.
