Chameleons are a special type of lizard that can change its color to blend into its surrounding. They use their long curly tail to hold onto the branch they are sitting on. 

 

The chameleon's eyes can rotate and focus separately on 180-degree arcs, so they can see two different objects at the same time. This gives them a full 360-degree field of vision.

 

Chameleons can change the color of their skin. One of the main reasons they do this to adjust to the temperature of a room. For example, if they are cold the might change to a darker color to absorb heat.  Another reason they do this is to attract a mate, they might change to a lighter color to do this. They might also change colors to hide from predators or pray but they rarely ever do this because they are very fast and can safely run away from most predators.
