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.
There is a small organ on the roof of the oral cavity called the vomeronasal organ, or Jacobson's organ.. The forked tongue is used to bring minute air particles into contact with this organ, and the snake then perceives and identifies the smell as prey, predator, or otherwise. unique part of the snake skeleton is the makeup of the skull and teeth. Adaptations in the skull allow snakes to eat prey much larger than themselves. The bones are connected by elastic ligaments, allowing a lot of stretch.
