The coloration varies from greenish or brownish on the back to silvery or white on the belly. The lateral line is white and strongly curved above the pectoral fins.

Distribution and habitat

The Atlantic pollock is native to the cold waters of the North Atlantic, including the Barents Sea, the Baltic Sea, the North Sea, and the waters around Iceland, Greenland, and Newfoundland. It prefers rocky bottoms and depths of 40 to 200 meters.
