Why do chameleons change color?

Answer: To signal mood and social status to other chameleons

To signal mood and social status to other chameleons ✓ — Correct! Chameleons change color mainly to communicate emotions and intentions. Bright colors signal aggression or courtship, darker colors show submission or stress. They adjust nanocrystal spacing in skin cells to reflect different wavelengths. Temperature regulation is a secondary benefit.

To confuse prey insects during hunting — Wrong. Chameleons are sit-and-wait predators relying on camouflage while stationary and their long, fast tongues for catching prey. Color changes are too slow to confuse insects and aren't used during hunting.

Because their skin automatically reacts to ultraviolet light — Wrong. Chameleon color change is controlled by the autonomic nervous system and is not a simple automatic UV reaction. They change color in response to mood, social context, or temperature—it's a complex physiological response, not a conscious decision.
