Description

The ocean triggerfish is a triggerfish (Balistidae) from the Atlantic Ocean. The species grows to about 65 cm and has a deep, laterally compressed, grey-blue body. Like all triggerfishes it can erect the first dorsal fin spine and lock it with a second spine, to wedge itself into a crevice. It occurs commonly near steep drop-offs of seaward reefs, sometimes in shallow water, solitary or in small groups in open water, often near drifting Sargassum weed. It feeds mainly on large zooplankton. The species is harmless to humans.
