Also found in: Dictionary, Thesaurus.
(Coryphaena hippums), a fish of the family Coryphaenidae of the order Percomorphi. The body is elongated (up to 2 m) and laterally compressed; the tail has a large and deeply notched caudal fin. The young are very different in shape from the adults. The fish weighs up to 30 kg. The back is blue green with white spots, and the sides and abdomen are silver or gold. The grenadier is found in all warm seas and as far north as the southern Kuril Islands. The flesh of the fish is highly valued, but the grenadier has no commercial significance since it does not form schools.
