First, a big surprise!

Many people think a chameleon changes colour to hide — to match a red apple or a checkered blanket. That's mostly a myth! 🙅

Chameleons change colour mainly to show how they feel, to stay the right temperature, and to talk to other chameleons.

Quick check — is this TRUE or FALSE?

"A chameleon can turn into any pattern to copy its background perfectly."

The secret is in the skin

A chameleon's skin has tiny special cells stacked in layers. The most amazing layer holds tiny crystals — far too small to see!

When the crystals sit close together, the skin looks cool blue & green. When they spread apart, the skin turns warm yellow, orange & red. Slide to try it!
