They might look rude, but snakes have a good reason to ick their tongues out. In addition to tasting things, a snake’s tongue is used to pick up smells in the air—such as the scent of fresh prey. Snakes have fairly good vision, but it is usually not good enough to track prey. The forked tip picks up scents coming from both sides, so the snake can tell which direction the scent is coming from.
