Why does an iguana stick out its tongue?

Answer 1

A snake sticks out its tongue to collect data for its Jacobson's Organ, an organ strategically located in front of the roof of the snake's mouth that functions as a chemical receptor. Each and every time the snake flicks out its forked tongue, it snares chemical particles in the air, which latch onto, or dissolve in, the moisture of the snake's tongue. Once the snake reels in its tongue, it inserts the tips of the forked tongue into the two awaiting openings of the Jacobson's organ where the particles, especially those of animal body odors, are identified, analyzed, and acted upon (if a nearby animal is potential food, or perhaps an enemy). Male snakes also use their tongues as part of a courting ritual, that is, the process by which they figure out if a certain female snake is interested in mating with them. The male snake jerks his body around, snapping his tongue in and out, and if the female ignores him, he knows to keep looking for a suitable partner. If she responds favorably, he's found his mate.

Answer 2

Rattlesnakes and other reptiles in the order of, Squamata stick out their tongues to smell the air as they sense with their tongue. Snakes have have a Jacobson's organ located on the roof of its mouth which functions as a chemical receptor. So when they sense the air they bring their tongue in and touch the Jacobson's organ and this sends impulses to the brain though nerves. (messages)
