What is sargassum?
Marine biologySeaweed
Quick Answer
Sargassum is a genus of brown seaweed that often floats freely at the ocean surface. It forms long mats that can drift across the Atlantic and provide habitat for marine life.
The Full Story
Unlike kelps that grow attached to the seafloor, many sargassum species have gas-filled bladders that help them float. Vast quantities are carried by currents, especially across the Atlantic, where seasonal blooms can become very extensive. Sargassum rafts serve as nurseries and hiding places for juvenile fish, shrimp, crabs, and sea turtles. In some places, though, excessive beaching of sargassum can create odor and cleanup problems.
