What are the external manifestations of killer whales suffering from depression?

Killer whales are highly intelligent animals, and the anatomy of the brain is strikingly similar to that of the human brain. The brain weight of killer whales divided by body weight is twice that of chimpanzees (7 times that of chimpanzees in humans). That said, killer whales are smarter than gorillas, and it's no coincidence.

Killer whales also show feelings such as happiness, fear, frustration, anger, and self-awareness. Killer whales can live in the wild for 80-90 years, but in captivity in humans, the average lifespan is only 20-30 years. They are very social animals with a complex range of social behaviors, hunting skills, and voice communication.

In addition, humpback whales are not very compatible with the great monarch killer whales of the sea, often harassing the hunt, seeking the weak, arousing the desire of chivalrous guests.

When killer whales (especially those that feed on killer whales and marine mammals) attack their prey, they make a sound to the distant humpback whales, causing the humpback whales to run over to hinder the killer whales' hunting operations and save the prey attacked by the killer whales. Kinship selection and reciprocity tend to occur between species that live in stable groups throughout the year. Humpback whales typically live in small and unstable groups, but there are several factors that determine that humpback whales can also produce kinship selection and reciprocity.

Juvenile humpback whales migrate with their mothers for a year after birth, during which they migrate with their mothers and are very knowledgeable about their mother's food and breeding grounds. As these calves grow up, they return to their mother's food sourcing area every year.
