Chameleons are squamates that belong to one of the best-known lizard families. A very impressive ans strange looking creature which could easily change the color of it’s skin. The main things chameleon species do have in common is their foot structure, their eyes, their lack of ears, and their tongue.
Their eyes are the most distinctive among the reptiles. The upper and lower eyelids are joined, with only a pinhole large enough for the pupil to see through. They can rotate and focus separately to observe two different objects simultaneously. It in effect gives them a full 360-degree arc of vision around their body!!!
