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.
