In Norwegian Current food webs, Atlantic cod can also operate as a higher-level predator when it feeds on forage fish and large pelagic invertebrates.

Fratercula arctica, the Atlantic puffin, is a diving seabird that feeds on small fish and large zooplankton.

Meganyctiphanes norvegica is a large North Atlantic krill species that often forms dense swarms and migrates up and down the water column each day.

Themisto libellula is a large predatory amphipod that lives in cold northern waters.

Calanus glacialis is a small crustacean that drifts in cold Arctic seas.

Gonatus fabricii is a squid of cold North Atlantic and Arctic waters that occupies an important midwater predatory role.

The Norwegian Current carries Atlantic water north along the Norwegian coast toward the Barents Sea and Arctic gateway. Spring blooms of diatoms and coccolithophores feed copepods, krill, fish, seabirds, seals, and whales. Because it links the North Atlantic to polar seas, it is a strong example of how circulation shapes subpolar food webs and ocean climate.
