The Animal of Camouflage

Do you know the animal that is well known for camouflage? Yes, it is the lizard! Lizards would usually find a back ground to support their skin such as a rock, tree branch, flower, and even the floor itself! They would sit there for hours and hours and wait for prey and to evade all predators. In my future drawing, the lizard is on the moon. The area it is in is covered by a invisible barrier that would give artificial gravity while blocking all the intense heat and coldness and bringing the exact amount of temperature they need. Also, we would loosen the amount of gravity given, making them have a sufficient amount of exercise
