The spotlight falls on coalfish.
Coalfish are widely distributed throughout the North Atlantic, their range extending across to the eastern seaboard of America where, confusingly, coalfish are called pollack. They feed mostly on small fish and sandeels, but will also forage on the seabed.
Occasionally confused with pollack, coalfish have a symmetrical jaw, whereas the lower jaw of the pollack protrudes. The lateral line of a coalfish is a distinct, straight white line, whereas there is a distinct curve above the pectoral fin on a pollack.
The colour of coalfish (Pollachius virens) ranges from a greenish brown, typical with small fish, to a stunning slate black displayed on the larger fish.
