A blue triggerfish (Pseudobalistes fuscus). They are wary of divers and tend to hide in reef crevices if approached. Difficult to photograph! Red Sea.

I was fortunate to photograph this blue triggerfish (Pseudobalistes fuscus), as the species is wary of divers and tends to hide in reef crevices if approached. All triggerfish feed mainly on molluscs and sea urchins, using their large sharp teeth to break open their prey.
