1: The IQ of snakes is not high in the animal family. As we all know, the intelligence of animals depends on the surface area of their cerebral cortex. The snake has a long body but a small head, and the proportion of head size to body size is low, which determines that it does not have the innate conditions of high IQ. However, this does not mean that snakes are hopelessly stupid. That was not the case. Under certain conditions, snakes perform quite well. For example, snakes have a good memory. Some snakes can clearly recognize people or animals that have hurt themselves even years later, and then wait for revenge. This shows from the side that the snake is a vengeful animal, so try not to provoke it in daily life.
2. Actually, it is not rigorous to divide animals into higher animals and lower animals. Animals are king as long as they can adapt to environmental changes and reproduce. Therefore, higher animals and lower animals are only relative, and all creatures in nature can be higher or lower than one or several creatures. This is a relative concept. Snakes are reptiles and are often called cold-blooded animals. Although snakes are quite big, birds are taller than snakes if compared with them. In fact, birds are more complex and advanced than ordinary amphibians, fish and reptiles. Generally speaking, snakes are not higher animals.
Snakes have a sense of smell, and their tongues often stick out. Odor chemical molecules in the air can attach to the tongue and produce a sense of smell through a nose hoe. This snake has poor eyesight. Although there are a pair of bright eyes, it basically has no effect, just like 1000 degree myopia. Unlike other animals, snakes can't hear air-borne sounds, but because they crawl close to the ground, they are very sensitive to vibrations from the ground. The so-called startle the snake means that the vibration generated by mowing grass is perceived by the snake, and the snake runs away, and the snake is extremely sensitive to the footsteps of people and animals.
