Black triggerfish

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.


The fish are circumtropical and are found in Hawaii, up through Polynesia, westward to the East Indies and across the Indian Ocean. The Black triggerfish is also located around the southern coast of Africa.


This species is found in open waters, shallows, and exposed reefs.


On average, 12 inches, although it can grow to be up to 18 inches.


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