Sea lettuce (<i>Ulva lactuca</i>) growing on the side of an old stone quay in Govik, Lysekil Municipality, Sweden. In front of the <i>ulva</i> are some serrated wrack (<i>Fucus serratus</i>) and at the top right a few strands of knotted wrack (<i>Ascophyllum nodosum</i>). The red in the background is red algae. The image is stacked from four photos to reduce glare and reflections on the water surface.
