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 has a very long tongue and they use it to allow them to smell around them. As they flick it in and out they are able to smell what all is around them. They have the Jacobsonâs Organ that allows them to do this just like snakes. Lizards are typically deemed as harmless in the wild.
