Cis forCamouflage
Camouflage is a way that animals can blend into the backgrounds by making themselves look as much like the background as possible. Some flat fish look exactly like the bottom of the sea. Some insects look exactly like the leaf they sit on. Can you see the insect in the picture? (it is at the bottom right, look closely)
A mirage happens when there are areas of air close to each other at different temperatures, which causes light to bend. This often happens when there is a layer of very hot air just above a road. The result is that something that should be seen in one place is seen in another place. Mirages can look a lot like water on the ground, reflecting the sky.
