<i>Porphyra umbilicalis</i> (IMAGE) University of Maine Caption Porphyra umbilicalis (laver) attains high biomass despite the high levels of stress in its habitat in the upper intertidal zone of the North Atlantic, as shown here at low tide at Sand Beach, Acadia National Park, Maine. Laver is a human food, and is being developed as an aquaculture crop by professor of marine sciences Susan Brawley and her team at the University of Maine. The completed genome provides insights to its nutritional value, especially to its content of minerals such as iron and vitamin C, vitamin E, and B vitamins including B12.
