Shades of black

Today, I encountered several black durgon (humuhumu ele ele) in various color phases.  Most often this triggerfish looks basically black, with pale blue bands at the base of the dorsal and anal fins.  But when the fish are in the right mood, and the light conditions are favorable, a gorgeous array of Maori-like, blue markings show up on the face and body.

Always a treat to see their blue and gold tones and graceful swimming.
