Description

The Muscat jawfish is a jawfish (Opistognathidae) from coastal waters of the western Indian Ocean and Persian Gulf. The species grows to about 45 cm and has a stocky forebody with a very large mouth and large eyes. As a bottom-dweller it digs and lines a vertical burrow with pebbles, from which it protrudes its forebody to snap at passing zooplankton; when threatened it withdraws backwards into the burrow. The male broods the eggs in his mouth. The fish is harmless to humans.
