Do snakes really smell with their tongues? Snakes do use their tongues to smell! Snakes have nostrils, just like humans. But a snakeâs tongue is also very important. When a snake flicks its tongue in the air, it picks up tiny chemical particles. When the snake brings its tongue back into its mouth, the tongue fits into a special organ on the roof of the mouth. This special organ is called the vomeronasal system. The vomeronasal system takes those tiny chemical particles and tells the snake what they are.
Snakes do not have especially keen senses of sight or hearing. They rely instead on special sense organs to provide them with information about their environment.ertain bones in a snake's head respond to sound waves and transmit them to the inner ear. A snake's tongue has few taste buds. It is used with an organ of smell called the Jacobson's organ, which, along with the nostrils, provides snakes with a keen sense of smell.
