Range and Identity
Arctogadus glacialis is often called Arctic Cod, while Polar Cod is also widely applied to Boreogadus saida. The scientific identity is therefore essential when reading a northern fish record. Measurements or ecological observations attached only to the common name may concern the other species.
Habitat and Behavior
The species occurs in Arctic waters, including Greenland regions, with offshore and shelf-edge records. Ice association is an important part of its setting. That association should not become a claim that every individual lives directly against ice or remains at a fixed depth throughout life.
Food and Life History
Fishes and crustaceans are recorded foods. The species has separate sexes and reproduces by laying eggs. The upper length reference is 32.5 centimeters total length. No maximum mass is calculated from that length, and a reproductive schedule for Boreogadus is not transferred to this fish.
Field Note
Write the scientific name beside a Polar Cod observation. In Arctic records, that small addition prevents two distinct fishes from being combined under one familiar common name.
