[Note Guidelines] Photographer's Note
The family Chamaeleonidae are a distinctive and highly specialized clade of lizards. They are distinguished by their parrot-like zygodactylous feet, their separately mobile and stereoscopic eyes, their very long, highly modified, and rapidly extrudable tongues, their swaying gait, and the possession by many of a prehensile tail, crests or horns on their distinctively shaped heads, and the ability of some to change color. They are uniquely adapted for climbing and visual hunting.

Description of this Lizard:-
There is only one species of chameleons found in the Indian subcontinent, scientifically known as Chamaeleo zeylanicus. The term 'chameleon' is a combination of two Greek words, 'Chamai', meaning 'on the ground/earth' and Leon, meaning 'lion'. Thus, 'chameleon' means 'earth lion'. The foot structure, eyes and tongue of all the chameleons are the same. Read on to get more information on the Indian chameleon:

Physical Traits
The body of the chameleon lizard is covered with granular scales and measures upto 37 cm in length. Its feet are split into two main fingers, each of them attached with sharp claws that help in climbing trees. The upper and lower eyelids of a chameleon are joined and there is a small pinhole through which the pupil can be seen. The chameleon can focus each of the two eyes in different direction and observe two different objects simultaneously.

One of the most interesting features of an Indian Chameleon is its extremely long tongue, which at times may exceed its body length also. The tongue is sticky at the end, which helps the reptile in catching prey. The moment the tongue of a chameleon hits a prey, it forms a small suction cup and draws the prey into the mouth. Chameleons do not have ears and vomeronasal organ.

Ability of Changing Color
All the chameleons have the ability to change color whenever they are subject to changes in stimuli, like a change in light, temperature or emotion. For example, when angered, they are likely to become darker in color.

Mating Behavior
The breeding season of the chameleon lizard falls around the month of October. Ten to thirty eggs are laid at a time and the gestation period is 3 to 6 weeks. Before laying eggs, the female chameleon digs a hole in the ground, between 4 to 12 inches deep, and deposits her eggs in that hole. The eggs hatch after a period of 3 months.

Diet
Chameleon lizard survives on a diet of locusts, mantids, crickets, and other insects.

Hi, this is a nice photograph but you got the identification wrong. If you read your Note carefully, it makes it quite clear that the description does not match with your photograph. Your photograph is that of Peninsular Rock Agama,Psammophilus dorsalis - male in breeding plumage. You can refer this here - http://en.wikipedia.org/wiki/Psammophilus_dorsalis
