Zostera marina. This species is the most wide-ranging marine flowering plant in the Northern Hemisphere
This species is the most wide-ranging marine flowering plant in the Northern Hemisphere.[1] It lives in cooler ocean waters in the North Atlantic and North Pacific, and in the warmer southern parts of its range it dies off during warmer seasons.[2] It grows in the Arctic region and endures several months of ice cover per year.[3] It is the only seagrass known from Iceland.[3] It can be found in bays, lagoons, estuaries, on beaches, and in other coastal habitat. The several ecotypes each have specific habitat requirements.[citation needed] It occurs in calmer waters in the sublittoral zone, where it is rarely exposed to air.[2] It anchors via rhizomes in sandy or muddy substrates and its leaves catch particulate debris in the water which then collects around the bases of the plants, building up the top layer of the seabed
