I believe this is an African Water Monitor, but I’m a neophyte naturalist.
This was taken at the Red Cross Snake Farm in downtown Bangkok.
These little lizards were one of the most common animal lifeforms at Hampi. They blend into the rock quite well despite the broken white or yellow line of dots on their backs, which itself blends into the splotched pattern of the creature.
I believe they are called Psammaphilus Dorsalis, Peninsular Rock Agamas, or South Indian Rock Agamas. [However, I know nothing about lizards and am open to correction by a herpetologist.]
