I am a reptile and exist in varied colours and size
I have long tongue, a swaying gait and crests on my snout
If I am large, I also have a beautiful, prehensile tail
I thrive in warm habitats from rain forests to deserts

My feet help me grip tightly to narrow or rough branches
My distinctive eyes help me observe two objects together
Being special, I can see in both visible and ultraviolet light
I can sense my prey from a five to ten meter distance

My tongue is twice my size and has an elastic recoil mechanism
I love insects and my long tongue helps me grab my victim
I lock my prize on my tongue with wet adhesion and suction
I survive in both heat and cold with my thermoregulation

You may be unfamiliar with the above facts about me
What I will share now, will help you recognize me this instant
I protect myself by changing my colour as per my surroundings
My top skin crystals reflect the longer wavelengths of light

When I am relaxed, I reflect the colours blue and green
When I am excited, I appear as yellow, orange, green, and red
By now, you must have guessed my identity, yes, you are right
I am a chameleon, I swiftly adapt and escape from your sight
