Snakes have an amazing sense of smell. They can use their tongues to pick up on all kinds of scents in the air.

Whenever we smell something in the air, we are actually sniffing tiny building blocks called molecules. These molecules are what make up the scents of everything around us—things like baked bread, fresh-cut grass, and warm cookies.

If you were a snake, you might sniff out the scent of a slug or mouse. You’d use your tongue to pull the molecules from the air into your mouth.

Then those molecules would reach a part of the roof of your mouth called the Jacobson’s organ. This organ helps de-code the molecules into smells. The smell might help you find some prey or let you know to slither away from a predator.

I learned all about snakes from my friend Rocky Parker. He earned his master’s degree in biological sciences at Washington State University and is currently an assistant professor at James Madison University in Virginia. He is very curious about how snakes use their senses.
