The black durgon is a triggerfish, named humuhumu 'ele'ele in Hawaiian. They are graceful swimmers and fun to watch, but often difficult to approach. When viewed under the right conditions, they display a lovely pattern of blue lines and golden hues.
Today we encountered some in a cleaning station that were displaying the striking blue pattern.
