What Do Reptiles See?

Pupil shape and eye position provide some clues to what reptiles see, and when they hunt. Reptiles with round pupils are usually active during the day, and probably see in color. Slit-like pupils are common in nighttime predators, which see in black and white.

Basilisk eyes
The green crested basilisk has round pupils.

Copperhead eyes
The copperhead has slit-like pupils.

Chameleon eyes
A chameleon's eyes move independently, allowing it to see two different views at once. When it spots a meal, both eyes focus on the prey.

Alligator eyes
An alligator's eyes are high on its head, enabling it to see above water while most of its body stays submerged.
