Can Snakes Smell Anything?
Share this
Most snakes have an excellent sense of smell, in part to make up for their poor eyesight and limited hearing. Rather than a conventional nose, however, snakes sniff with an organ at the roof of the mouth called a Jacobson's organ, which is also found in a few lizard species. Snakes flick their tongues to collect scent particles for this organ. The prongs of the forked tongue is stuck into a pair of holes in the Jacobson's organ. The snake's nostrils also play a supporting role. Do Snakes Have Ears? Can Snakes See Well? How Do Snakes Swallow Large Animals?
