Description
The grey triggerfish is a reef fish of the family Balistidae reaching about 66 cm. The deep, laterally compressed body is grey-green with a few faint dark bars and small pale-blue spots on the upper half and the fins. Its hallmark is the erectile first dorsal spine, which locks upright like a trigger once a second spine engages. The small mouth bears strong teeth used to crush shellfish and molluscs. The species lives in the Atlantic and Mediterranean and guards its eggs in sand nests. Fishing pressure has left it assessed as Vulnerable, and consumption has been linked to ciguatera poisoning.
