The black triggerfish, Melichthys niger, called Humuhumu'ele'ele in Hawaiian, is a blimp-shaped triggerfish with bright white lines running along its dorsal and anal fins. When in the water, it appears to be completely black. However, if it is taken out and exposed to bright light, one can see that it is actually of a dark-blue/green coloration.

Size
On average, 12 inches, although it can grow to be up to 14 inches.

Diet
Omnivorous. Feeds upon small fish and squid. Shrimp, zooplankton, algae, and other marine plant life.
