Sargassum floats due to the presence of gas-filled bladder structures called pneumatocysts along its fronds or blades. These bladders provide buoyancy that allows the seaweed to stay afloat on the water's surface.
Pneumatocysts are filled with carbon dioxide. Kelp use this adaptation to float toward the water's surface. The higher it floats, the more sunlight it could get for photosynthesis.
They are called pneumatocysts. They are the stinging cells used for killing prey, as all cnidarians are predators. They are cells that contain poison, and have little barbs on them to inject the poison with. With some cnidarians, the little barbs are all that you feel because their poison is only strong enough to kill plankton. With other cnidarians, however, the poison in the pneumatocysts is strong and can be deadly. The main purpose of the pneumatocysts is to kill prey, but they are also useful against predators.
