Pleuston

the aggregate of aquatic organisms that live on or near the surface of a body of water. Most diverse are the representatives of marine pleuston. Many pleustonic organisms are characterized by the formation of gas chambers (for example, the siphonophore Physalid) or the excretion of foamy rafts of bubbles (for example, the sea anemone Minyas and the mollusk Janthind). Others use the surface of the water as a support (for example, the mollusk Glaucus). Pleustonic plants include sargasso.
