Description
The Crevalle Jack is a large, powerful marine predator characterized by its silvery body, a distinctive black spot on the operculum, and often yellow fins. These highly active, schooling fish inhabit coastal waters and estuaries throughout the Atlantic Ocean. Due to their substantial size and predatory behavior, they are primarily suitable for large public aquariums or as game fish.
