Snakes use their tongues to collect odor particles around them. First, they quickly put their tongues into the air and put them in their mouths. In their mouths, they inserted two small forks of their tongues into the holes in the mouth wall. These caves are Jacobson's organs and lead directly to the brain.

Although a snake's nostrils can smell the smell, the tongue and Jacobson's organs enhance the snake's ability to perceive the smell, and because of its strong sense of smell, the snake's letters have the ability to tell the direction.

The living habits of snakes

Snakes belong to temperature-changing animals and are very sensitive to the temperature response of the surrounding environment. The outdoor temperature of 20~30℃ is suitable for the growth of snakes; When the temperature is about 25~32℃, the activity of leaving the nest is more frequent;

When the temperature drops to 20~ 13℃, snakes will instinctively look for warm places; Above 33℃, find a cool place or climb into a pool or ditch to enjoy the cool.

On sunny days in early spring, the temperature rises above 18℃, and snakes like to go out to bask in the sun at noon. After the summer rainstorm, especially at night, it is almost their nest. ?
