The Picasso Triggerfish earns its name from the bold, asymmetrical markings that cover its head and body — a striking mix of blues, yellows, and blacks that recall abstract art. Found on Indo-Pacific reefs, this stocky triggerfish typically hovers near the seafloor or amid coral and rocks, where it grazes on small invertebrates and algae. It can lock its dorsal spine erect as a defensive mechanism and is known for territorial aggression, especially during breeding. Divers will spot it at moderate depths, usually in areas with plenty of shelter and rubble.
