About this species
Species identity
Metridia longa is a cold-water copepod that migrates vertically through the water column and feeds on planktonic food. It is common in northern seas and helps transfer production from small plankton to fish and other predators.
Where it lives
Metridia longa occurs in the North Atlantic and Arctic, especially in cold subpolar and polar waters. It is regularly found in Norwegian Current systems where strong seasonal production supports zooplankton communities.
Role in the ecosystem
Copepod helps explain how marine food webs function through its ecological role, habitat use, and connection to broader ecosystem change.
