Description

The finescale triggerfish (Balistes polylepis) is a triggerfish of the family Balistidae from the eastern Pacific. The species has a tall, laterally compressed, grey-brown body and reaches about 76 cm. Characteristic is the first, stout dorsal-fin spine that can be erected and locked by a second spine like a trigger, with which the fish wedges itself in crevices. With its powerful mouth and strong teeth it crushes sea urchins, crustaceans and mollusks. It lives on rocky reefs and boulder-strewn slopes; juveniles are pelagic. The species is a valued food fish but can bite with its mouth when handled.
