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.
