One of the most intelligent animals in the world is humans. But if we only consider non-human animals, then this question is harder to answer, because different animals have different intellectual performances and abilities.
Here are some animal species that are considered relatively intelligent:
1. Gorilla
2. Dolphin
3. Dog
4. Crow
5. Owl
6. Elephant
7. Fox
8. Homo sapiens (such as chimpanzees, golden monkeys, etc.)
9. Crocodile
10. Reef fish
It should be noted that the evaluation criteria of IQ may be controversial and have different views among different scholars and researchers, so there is no generally accepted answer to this question.
