The Namaqua Chameleon

The Namaqua chameleon has evolved several adaptations to cope with desert conditions: they excrete salt from nasal glands to conserve water and dig holes to aid in thermoregulation.

They also use their ability to change colour to aid in controlling temperature, becoming black in the cooler morning to absorb heat more efficiently, then a lighter grey color to reflect light during the heat of the day or showing both colours at the same time, neatly separated left from right by the spine.
