- The sailfin has a vestigial eye atop its head. It's called the parietal or pineal eye. Parietal refers to the top of the skull. A pineal eye is also called a third eye. Some reptiles like the sailfin have it. The pineal eye is sensitive to the angle of the sun's rays, and is thought to be a homing mechanism.
Sailfin lizard behavior and facts

- The lizard defends itself from predators by escaping into the water, often dropping from tree limbs, where it rests.
- Hand-raised individuals become tame and seem to like being handled.
