Facts about The Camouflage Skills of Chameleons
- 05
A chameleon's skin contains pigment cells called melanophores that can disperse or concentrate melanin, influencing how the iridophore layer's reflected colors appear.
- 04
Some chameleon species can complete a full color change within seconds, driven by rapid mechanical tuning of the spacing between iridophore nanocrystals.
- 03
Panther chameleons and several other species possess two superimposed layers of iridophore cells, with the deeper layer specialized for reflecting near-infrared light.
- 02
Color change in chameleons serves primarily as social communication — signaling dominance, mating readiness, or stress — rather than as camouflage from predators.
- 01
Chameleons change color primarily through active tuning of a layer of iridophore cells containing nanocrystals that reflect different wavelengths of light, not through pigment movement.
