A wall of noise ... 

Easily the loudest lizards in the world. Well, they are at 3 a.m. when you're trying to sleep! The Tookay, a large gecko that most Thais are scared to death of. They are very common, but difficult to photograph. Their colours vary, as does their size depending on age. I think they look particularly beautiful. This one I saw at a building just outside Khao Yai, but I have seen them everywhere.
