Description

The yellowmargin triggerfish is a large triggerfish (Balistidae) from the Indo-West Pacific. The species has a robust, grey-brown body with yellow-edged fins, to which the name refers, and powerful jaws with strong teeth. It inhabits coastal to inner reefs, lagoon slopes and estuaries, often on silty bottoms. It blows prey out of the sand with a jet of water and cracks sea urchins, shellfish and crustaceans. In the breeding season it fiercely guards a bottom nest and can then give a painful bite; otherwise it is not aggressive.
