how are snake sense

The vast majority of snakes present a very poor sense of vision, which is why they must use their language to recognize odors and interact with the environment around them. With a characteristic movement up and down, these reptiles show their tongue and return it to the mouth to analyze the information and discover if it is food or an imminent danger that lurks.
Being bifida, its tongue is able to recognize a wide spectrum of aromas, and even the direction from which such smells come. On the other hand, it is necessary to emphasize that snakes do not have ears, and to listen, they rely on the vibrations of the ground. However, some species have infrared vision, which allows them to determine the heat of objects and animals around them. Through their senses, snakes can even expel the food they have just swallowed, in case they should escape.
