1. They have long tongue having a sticky tip on the end, which serves to catch prey items that they would otherwise never be able to reach with their lack of locomotive speed. The tip of their tongue is a bulbous ball of muscle, and as it hits its prey, it rapidly forms a small suction cup. Once the tongue sticks to a prey item, it is drawn quickly back into the mouth, where the chameleon's strong jaws crush it and it is consumed.
2. The characteristics of changing their skin colour make them one of the famous lizard family species. Changing the skin colour is an expression of the physical and physiological condition of the lizard. The colour also plays an important part in communication between other chameleons. If they are fearful or territorial, their emotions will evoke a particular color/pattern.
3. Chameleons have teeth to grasp onto food. Their teeth are also used to help them crush and kill their food. They may chew or swallow their food whole. They can also use their teeth for tearing chunks off and then swallow. Some chameleons hold the dead prey in their mouth for several moments before swallowing it.
4. They lay eggs in a 4 to 12 inches deep hole. Some species lay 2 to 4 eggs while other species lays 80 to 100 eggs. Some species of chameleon give birth to young ones.
5. They hear vibrations in the air, which help them find food and stay safe from their enemies. They are almost deaf, but can hear tones and feel vibrations.
6. 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 their eyes separately to observe two different objects simultaneously. It in effect gives them a full 360-degree arc of vision around their body.
7. They have zygodactyl foot, on each foot the five toes are fused into a group of two and a group of three, giving the foot a gripping and lifting like appearance. With their specialized feet, they grip tightly to narrow branches.
