Mastocarpus

Mastocarpus is a genus of red algae found in coastal waters, known for its importance in marine ecosystems and as a source of carrageenan—a substance used in food products, cosmetics, and pharmaceuticals for its thickening and stabilizing properties. These algae can grow on rocks, shells, and other surfaces, and they often display a reddish color. They play a key role in habitat formation and provide food for marine animals. Mastocarpus species are also studied for their potential in biotechnological applications due to their unique cellular compounds and resilience in various marine environments.
