Seagrass is defined as the only flowering plant (Angiospermae) that can fully adapt to waters with relatively high salinity or live submerged in water and has rhizomes, true leaves, and true roots. Seagrass grows abundantly, especially in open intertidal areas and coastal waters or lagoons with a substrate of mud, sand, gravel, and broken dead coral, at a depth of 4 meters. Seagrass beds are formed on the seabed that is still penetrated by sufficient sunlight for their growth.
