The Gonorynchidae are a family of long thin gonorynchiform ray-finned fish, commonly called beaked salmon or beaked sandfish that live on sandy bottoms near shorelines. About five known species are placed in the single genus Gonorynchus. All have a distinctive angular snout (hence the name) that the fish use to dig themselves into the sand. The most widespread species is Gonorynchus gonorynchus, found in scattered locations worldwide. It can reach up to 60 cm (24 in) in length. It is a nocturnal fish, feeding on invertebrates at night and burrowing into sand or mud during the day.
