7. Sargassum Protects the Beachfront
The algae serves as buffer on the beach by reducing wave and wind erosion. It also protects the sand in dunes, making them more resilient. Less erosion means more sand on the beaches to structurally support beachfront properties and for people to play in.

8. Food for the Birds
When the sargassum and all of the organisms living within the masses of seaweed wash ashore, it provides food for pelagic seabirds and pelicans.

9. When Sargassum Sinks
Berry-like gas-filled structures, called pneumatocysts, make up the plant. These “berries,” which are filled mostly with oxygen, cause the algae to float. When sargassum loses its buoyancy, it sinks to the seafloor, providing energy in the form of carbon and also food sources to fishes and invertebrates in the deep sea.
