Do all snakes use their tongues to help them smell odors?

Yes, all snakes use their tongues to help them detect odors, a process known as chemoreception. By flicking their tongues in and out, snakes collect scent particles from the air and then transfer them to the Jacobson's organ, a specialized sensory structure in the roof of their mouth. This allows them to "taste" the environment and locate prey, mates, or identify threats.
