Parp! Trumpetfish…
Trumpetfish can camouflage themselves extremely well and even use other fish (and divers) to hide behind whilst hunting. This particular fish was shadowing me all over this wreck in Sabang bay in the Philippines. They often hang vertically in the water as you see here, and use their low profile body shape to remain invisible to their prey… Clever bastards.
