Actually, the intelligence of different animal species cannot really be compared scientifically - the natural requirements are simply too different, think, for example, of the completely different brain size of an ant and a monkey. However, certain behaviors can be used to determine what kind of thinking, given their brain mass, the animals are capable of. As expected, the dolphin, which is often said to be the most intelligent animal, is at the top of the list of the most intelligent animals. The marine mammals recognize each other by their sounds, which is comparable to the human naming - and is unique in the animal world.
Monkeys are thinking about the future
Elephants are also particularly clever. The gentle giants easily pass the mirror test and use, for example, tufts of plants and twigs to scare away flies. Perhaps the best-known tool professional among animal species is the monkey. In addition, the animals closely related to us can think about the near future and are even sneaky towards their peers, which requires an understanding of the other.

Raven is also familiar with the use of tools. You can skilfully bend a wire to use it and sometimes even count it, as demonstrated by a raven named "Jakob". Last but not least, the horse is one of the most intelligent animals in the world. The loyal riding companions can read the facial expressions of people and think of various strategies to solve problems.
