Black Durgon

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 a 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.
