This is a “Green Emerald Gecko”. It is endemic to the Andaman Islands of India.
We were on vacation, in the Andaman Islands. At the resort, when I was having dinner, I spotted this gecko in the hanging light above my head. I gobbled up my dinner, ran to our room, and brought my camera. Then, I stood on the dinner table and captured this gecko. Whenever I moved a lot it used to crawl back to the end of the light, then come back to the front after some time!
