It often feeds by turning over rocks, stirring up sand and biting off pieces of branching coral. It feeds on sea urchins, molluscs, crustaceans, tube worms and coral. The titan triggerfish is diurnal and solitary. Look for Mustache Trigger’s in the Seychelles, Christmas Island, Cook Islands and Australia. With a length of up to 75 centimeters (30 in), it is the largest species of triggerfish in its range. Mustache “Titan” Triggerfish: ( Balistoides viridescens) is a large species of triggerfish found in lagoons and on the flats around reefs. There are several others that you may catch as well, but the following are those most commonly stalked on the flats by anglers. The eyes are small, set far back from the mouth, at the top of the head.Įven with such a diverse range of species among the triggerfish family, there are really just 3 types that we frequently target with a fly rod. The head is large, terminating in a small but strong-jawed mouth with teeth adapted for crushing shells and coral. Triggerfish have an oval shaped, highly compressed body. Triggerfish are adept at sliding into small thin crevices and their dorsal spines are then erected to lock them into place. The spine is also used to lock the fish into crevices or small spaces making it difficult for predators to extract them. The spine is used for defensive purposes because when raised it makes it difficult for a larger predator to swallow them. Only when this trigger spine is moved can the main spine be lowered. The main dorsal spine is kept erect by a second spine which locks the dorsal spine in place. Triggerfish obtain their name from the locking mechanism used to hold the dorsal spine in place. Most are found on the shallow flats in coastal habitats, especially around coral reefs, making them a perfect target for fly fishermen. Trigger’s inhabit tropical and subtropical oceans throughout the world, with the greatest species variety in the Indian Ocean and the Pacific, but the Atlantic has a few species as well. There are about 40 species of Triggerfish, often brightly colored, in the taxonomic family Balistidae. ![]() ![]() International Fly Fishing Travel Magazine.Skip to content The Fly Shop 800♶69♳474 Menu
