Sargassum

Sargassum is a type of large seaweed or brown algae that naturally floats in the ocean. It forms expansive drifting mats in the Atlantic Ocean, providing habitat and food for marine life. These floating masses can transport across vast distances, sometimes washing ashore on beaches. While Sargassum plays a vital role in marine ecosystems, excessive amounts can cause problems such as crowded beaches, harm to marine animals, and water quality issues. Its presence is influenced by factors like nutrient levels, ocean currents, and climate conditions, making it a dynamic component of oceanic environments.
