The stone triggerfish (Pseudobalistes naufragium) is the largest species of triggerfish.
It is found at reefs and over sandy bottoms in the eastern Pacific, ranging from Baja California (Mexico) to Chile.
It can reach 1m (03feet) in length but is more common at about half that size. Covered entirely with platelike scales aside from one scaleless area behind the jaws. The stone triggerfish has 16 strong protruding teeth with 8 held in each jaw.
Pseudobalistes naufragium feeds on small crustaceans, mollusks, and sea urchins.
