Black whales have stable social relations and complex languages, and their attitude towards human beings depends on human attitudes towards killer whales. Moreover, killer whales have amazing recognition and memory ability. They can distinguish people who have met once and will never forget them. Humans can't do this.

Whales themselves inherit memories, and both recipes and behaviors are handed down by ancestors. It is very likely that in very ancient times, people and whales had some kind of agreement, but with the passage of time, we completely forgot and even wondered about the behavior of whales.

Extended data:

1, killer whales attack people in single digits, but wild killer whales don't. Only one case has a detailed and reliable record. Tilikum: A captive killer whale that has been artificially abused for more than 30 years.

2. Black whales are highly socialized animals, and some group families are the most stable families in the animal kingdom. Some complex social behaviors, hunting skills and voice communication of killer whales are considered as evidence that killer whales have their own culture. It is distributed in almost all marine areas, from equator to polar waters.

3. 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 an animal with a high IQ. It has feelings like primates, a strong language system, few dialects between animals, and even uses tones to mock people who have failed in hunting.
