Fish Identification: Black Triggerfish

Black triggerfish are also known as black durgon, but should not be confused with their close relatives the Indian Triggerfish and the Black-finned Triggerfish.

Physical description

Black durgon average about 12 inches in length, but can grow as large as 14 inches.

They have the common triggerfish body shape: oval with soft dorsal and anal fins of equal size. Both fins are white at the base, while the rest of the black triggerfish appears black. I say appears, because taken out of water and put under light, the fish is colored dark blue / blue-green.

Geography and habitat

Black triggerfish live in tropical waters across the entire globe. They are found in practically all depths.

The fish is also usually solitary.
