Definition
"Fucus" is a genus of brown algae, often called rockweed or wrack, commonly found in the intertidal zone. These algae are characterized by their flattened, branched bodies, and the presence of air bladders that help them float. They attach to rocks and are able to withstand exposure to air during low tide. They are important primary producers in their ecosystems. Think of them as the 'foundational plants' of the rocky shore 🌿.
