What are the physiological adaptations of the bearded dragon (lizard) for thermoregulation

i have an assignment so i need a good answer

1. Changing tint- Beardies can change from a lightish brown to a darkish brown. Darker colors absorb light better ( + Heat ) while light colors don't absorb it as well ( - Heat ) I believe beardies have a special chromatophore cell type in their skin that causes this change in color but I'm not sure.

2. Spreading out their body- Their rib cage can be stretched out like a sail making them almost three times as wide as normal. This creates more surface area to abosorb sunlight.

3. "Panting"- If a dragon is too hot they will open their mouth. Water in saliva evaporates cooling the body.
