Chameleons are known for their ability to change color, a process primarily driven by their mood, temperature, and environmental factors. This color change occurs through specialized cells in their skin called chromatophores, which contain different pigments. By expanding or contracting these cells, chameleons can display a range of colors. In addition to chromatophores, chameleons also have iridophores and leucophores, which reflect light and contribute to their color display. This ability serves various purposes, including communication with other chameleons, camouflage from predators, and temperature regulation. Overall, color change is a vital adaptation for these unique reptiles.
