Detailed explanation-1: -Many lizards can change colour. The most notable groups in this regard are the chameleons and the anoles. Some species can change from bright green to deep, chocolate brown, and patterns such as lines and bars may appear and disappear along their bodies.

Detailed explanation-2: -The lizard gains heat energy via thermal radiation from the Sun, the atmosphere and the ground. Heat energy is lost via conduction from the body to the ground, by evaporative water loss, convection and thermal radiation to the sky.

Detailed explanation-3: -It isn’t a conscious decision in the way we think about it, and it could be partly driven by hormones, but they are able to assess their surroundings and then trigger a response in their skin.” Reptiles change skin colour by altering the distribution of natural pigments like melanin inside their skin cells.

Detailed explanation-4: -In green anoles, color change is a response to external factors, such as temperature and humidity. It may also be influenced by hormonal changes. Whether lizards experience emotions comparable to humans remains a mystery.
