A blue crest of a wave ...

One of the highlights of visiting Chiang Mai (March-May 2010) was spotting several species of lizards and snakes. Here is what I believe to be a Blue Crested Lizard. I could be wrong, but it seems to match. I saw two males near a waterfall in Chiang Mai.

Order: Unknown

Family: Unknown

Vernacular name: Blue Crested Lizard

Scientific name: Calotes mystaceus (I think)
