Summary

Saltwater fish, Black triggerfish or black durgon have oval shaped, highly compressed bodies, with bright white lines running along the dorsal and anal fins. From a distance, the colour appears to be completely black. However, upon closer inspection with good lighting, one can see that it is actually mottled dark-blue/green colouration, often with orange toward the front of the head. Black durgons are capable of changing colour. The first spine is stout and by far the longest. All three are normally retracted into a groove.
