Be aware of human danger.

Humans are the dominant species on the planet. We easily tame the largest animal on the earth: Turn elephants into circus performers or effective assistants for heavy work. In the ocean, humans have hunted sperm whales - the largest fish on the planet for hundreds of years, even putting some whale species on the brink of extinction, and killer whales are no exception.

Killer whales are very intelligent, but they are certainly not as intelligent as humans. As a result, many killer whales have perished at the hands of humans, throughout the hundreds of years of fishing and maritime history. In just three years, from 1978 to 1981, up to 346 killer whales were exterminated off the coast of Norway. This number only stops when there is a ban from the Local Government.

The lucky survivors never seem to forget that, and as mentioned, killer whales are smart enough to learn from the events they experience in their lives. A pod of killer whales is usually led by an adult female, and scientists believe it was this "wise mother" who passed on her bloody experiences to other members of the herd. knowing how to recognize and stay away from fishing boats.
