Titan Triggerfish (Balistoides viridescens): Some consider the Titan Triggerfish, sometimes called the Giant Triggerfish, to be the most dangerous fish in the Maldives. That is a bad rep because the normally peaceful Titan, which grows to 75 cm, only gets aggressive when defending its eggs during the nesting period. Female Titans lay their eggs in a shallow depression on the sandy bottom of sheltered inner reef slopes. Male Titans guard them until they hatch. They are concerned about other egg-eating fishes but will challenge anything including snorkellers on whom they can inflict a really nasty bite. However, move away and they will return to nest-guarding duties. Size apart the Titan can be identified by its yellow on black criss-cross body markings, distinctive yellow dorsal and anal fins edged in black, yellow tail fin edged in black and a black moustache streak above its mouth.
