Why do chameleons change color?
Show answer & explanation
Answer: Communication and mood
Communication and mood ✓ — 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. It's like mood ring biology!
Skin reacts to UV light automatically — Wrong. Chameleon color change is voluntary and controlled by the nervous system, not an automatic UV reaction. They actively decide to change color based on mood, social context, or temperature—it's a conscious process!
Confuse prey insects — 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.
