Titan Triggerfish
Alternative names: Giant Triggerfish, Moustache Triggerfish, Balistoides viridescens
The titan triggerfish is a large species of triggerfish that can be found in the Indo-Pacific oceans, although it is absent from Hawaii.
The titan triggerfish is very cautious when it comes to divers and if a diver comes too close to the territory surrounding the nest during reproduction season, they will be attacked.
