Lady Musgrave Island Nov 2010

They sure are. Couldn't believe the high contrast markings on the caudal peduncle - must be there so that predators target fixate and try to intercept at the back of the fish (increasing odds of escape). I wish I knew what these fish are - found myself woefully ignorant of fish species beyond our region and haven't come across any good resources online. May have to invest in a reference book next time I travel!

These are some cool looking fish! Any idea what they are? Surgeonfish of some kind?
