About this species

The black triggerfish or black durgon, called Humuhumu'ele'ele in Hawaiian, is a blimp-shaped triggerfish with bright white lines running along its dorsal and anal fins. From distance, it appears to be completely black. However, upon closer inspection with good lighting, one can see that it is actually mottled dark-blue/green coloration often with orange toward the front of the head. Black durgons are capable of changing color based on their surroundings.
