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.
The lizard can use these scent âcluesâ to find food or a mate or to detect enemies. Lizards donât have earflaps like mammals do.
