Leatherback turtle

Apolemia uvaria is a colonial siphonophore made of many specialized zooids that function together as one drifting predator.

Micromesistius poutassou is a pelagic gadiform fish that feeds on zooplankton and small nekton in the North Atlantic.

Mallotus villosus, the capelin, is a small schooling forage fish that feeds on plankton and small crustaceans.

Oithona similis is a tiny cyclopoid copepod that is common in cold and temperate marine waters.

Boreogadus saida, the polar cod, is a small schooling fish that plays a central role in Arctic and subpolar food webs.

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.

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.

Huge swarms consume fish eggs and larvae, preventing predator populations from rebuilding.
