Orcas are a group of whales. They are relatively large whales. They are a kind of carnivore, and they will eat many creatures in the sea as their own food. Their character is very fierce, attack is relatively strong, even sharks are afraid of them. However, they are relatively friendly to humans and generally do not attack humans on their own initiative. However, this is only in most cases, in some special cases they will also attack humans, such as in the case of human hunting them, and in the case of human provocation of them, etc., they are also likely to attack humans.
As mentioned above, although orcas are relatively fierce, they are relatively friendly to humans. After conducting research, biologists have found that there are three possible reasons for this phenomenon:
1. High IQ: Killer whales are creatures with relatively high IQ. They know that humans are mammals like them, so they will regard humans as their own kind. This is one of the reasons why they are more friendly to humans.
2. Food preferences: Killer whales are large creatures in the ocean. They usually feed on other creatures in the ocean, even some very large creatures. This is their food habits and preferences. As a result, they are not very interested in humans.
3. Tradition: Some biologists believe that in very remote ancient times, the relationship between human ancestors and killer whale ancestors was similar to that between us and dogs. After years of change, although the relationship between orcas and humans has become indifferent, some of them will survive, which may also be one of the reasons why orcas are friendly to humans.
