It is plainly coloured with brownish spots and a silvery body. It grows to a length of 30 cm. The Polar cod is found further north than any other fish species (beyond 84 degrees N) with a distribution spanning the Arctic seas off northern
Russia ,Alaska ,Canada , andGreenland .This fish is most commonly found at the water's surface, but is also known to travel at depths greater than 900 m. The Polar cod is known to frequent river mouths. It is a hardy fish that survives best at temperatures of 0-4 degrees
Celsius but may tolerate colder temperatures owing to the presence ofantifreeze protein compounds in its blood. They group in large schools in ice-free waters.The Polar cod feeds on
plankton andkrill . It is in turn the primary food source fornarwhal s, belugas,ringed seal s andseabird s. They are fished commercially in Russia.References
