Chameleons can move their eyes independently. This ability primarily provides what benefit?

• A. A wide field of vision.
• B. The ability to swim
• C. Enhanced hearing
• D. The ability to glow in the dark.

Answer: (A)

Moving eyes independently mainly gives a wide field of vision. Because each eye can rotate separately, a chameleon can scan scenery in multiple directions at once without moving its head or body, which creates a nearly surround-the-head view. This helps the animal keep watch for predators and spot prey while remaining camouflaged and still. When it’s time to strike, the eyes can still focus on a target to judge distance, but the primary advantage is the broad, continuous awareness of the surroundings. The other options—swimming ability, enhanced hearing, or glowing in the dark—aren’t linked to this eye movement, so they don’t explain the benefit.
