Clown Triggerfish

Scientific name: Balistoides conspicillum

The Clown Triggerfish often seems to be a preposterous combination of colors and patterns, but it actually makes some sense from a camouflage standpoint: The black and white honeycomb pattern on the underbelly probably blends in with the surface of the water when seen from below, while the patchy colored top side looks like the reef from above.

Although I didn't manage to get a good picture until I dived the Maldives, Clowns are plentiful all around Southeast Asia, especially in the Similans in Thailand.

Please note: Identification of fish, corals, etc. is a tricky business. It's entirely possible that I've incorrectly identified a photo I've taken. If you spot an error, please contact me so I can correct it and improve this resource.
