Sargassum bacciferum is a type of seaweed commonly found in the Sargasso Sea. This brownish-green algae is often referred to as "berry-bearing sargassum" because of the gas-filled bladders that help it float on the surface of the water. There are several synonyms for this species, including Sargassum angustifolium, Sargassum fuscifolium, and Sargassum natans. It is an important part of the ocean ecosystem, providing habitat and food for many species of marine life. However, in recent years, large blooms of sargassum have caused controversy due to their negative impact on tourism and the environment in coastal regions.
