Reef Fish
Titan Triggerfish
Balistoides viridescens · Bony fish — family Balistidae (triggerfishes); the largest triggerfish on Indo-Pacific reefs
Outside nesting periods a titan triggerfish is simply an impressive reef resident — a heavy, mottled excavator that flips rubble and bites through urchins and branching coral while smaller fish shadow it for scraps. During nesting everything changes. The female guards a shallow pit of eggs at the center of a territory shaped like an inverted cone widening toward the surface, so ascending feels like escape but actually keeps a diver inside the claim. The response drill is unglamorous and effective: level off, turn, and swim horizontally away low over the reef, keeping fins or a camera housing between you and the fish. Bites are not venomous but can pierce a wetsuit and break skin. Give any guarded patch of rubble a wide, flat detour and the drama never starts.

범위: Tropical Indo-Pacific from the Red Sea and East Africa to French Polynesia and southern Japan.
행동 특성: Territorial year-round, dramatically so when nesting; the guarded territory extends upward like an inverted cone above the nest pit, so climbing feels like escape but is not.

크기: 보통 0.5 m; 최대 기록 수심 0.75 m (total length).
이 생물 주변에서의 행동 요령
If charged, level off and swim horizontally away low over the reef, keeping fins or a camera housing between you and the fish; never ascend directly and never corner the animal.
보존
No major targeted fishery; large adults can carry ciguatera and are best left off menus.
