Orcas are a kind of whales. They are very smart creatures. Their intelligence quotient is very high, and their brains are relatively developed. They are smart in many ways. For example, they will not actively attack humans, but may be more friendly to humans. In addition, killer whales have their own social systems, they can cooperate with their own kind to hunt a kind of creature, and there are also competitive behaviors in their social systems. In addition, killer whales will have their own language system. Some researchers have studied this and found that the language system is very complex, and they will use this system to communicate with each other.
Orcas and dolphins are whales, and they are dolphins. Therefore, both of them are very intelligent creatures, they are friendly to human beings, they also have their own unique language system, and can use language to communicate with their peers. However, there is still a difference in IQ between killer whales and dolphins, and killer whales will have a slightly higher IQ.
In addition to the larger size of the orcas, their slightly higher IQ is also an important reason for the dolphin type in the orcas' food. In addition, the social groups of the two are also different, and the social groups of killer whales are more complex. Some researchers believe that this is because orcas are more intelligent and at the top of the food chain, they are more able to develop their own groups, which can also be equivalent to the social "civilization" of orcas than dolphins. Therefore, the intelligence of killer whales may be relatively higher.
