Description

The Galapagos jawfish is a jawfish (Opistognathidae) from shallow sand and coral-rubble water of the waters around the Galapagos in the eastern Pacific. The species grows to about 12 cm and has an elongate body with a large head and very wide mouth. As a bottom-dweller it digs and occupies a vertical burrow reinforced with pebbles into which it darts when threatened. The male broods the eggs in his mouth. It snaps at passing plankton and small invertebrates. The fish is harmless to humans.
