The Seagrass Beds Seagrasses are flowering plants that have adapted to living in the sea. These plants are frequently found growing in dense beds or meadows. Seagrasses are found mostly on soft sediment in estuaries and shallow coastal waters.
Seagrasses have extensive underground roots and rhizomes which anchor the plant in the muddy sands.
These roots absorb nutrients but, unlike their land-living relatives, they do not take up water. The stems and leaves of the plant grow out from the underground roots. The leaves are thin which allows for efficient capture of sunlight, absorption of nutrients and exchange of gases. Seagrass Cymadocea spp. Worldwide there are approximately 55 species, the greatest numbers of which are to be found in tropical seas.
