Fucus
Also called Rockweed, genus of brown algae, common on rocky seacoasts and in salt marshes of northern temperate regions. Adaptations to its environment include bladderlike floats (pneumatocysts), disk-shaped holdfasts for clinging to rocks, and mucilage-covered blades for resisting desiccation and temperature changes. The plant is between 25 and 30 centimetres (9.8 to 11.8 inches)
