Seagrasses are marine flowering plants. They are not true grasses and are more closely related to terrestrial lilies and gingers than grasses.
They often grow in large groups giving the appearance of terrestrial grassland – an underwater meadow.
They have roots, stems and leaves and produce flowers and fruits. They are the only flowering plants that can live underwater.
They are found in salty and brackish waters from the tropics to the Arctic Circle.
They thrive in shallow coastal waters where there is shelter from drying winds, wave action, and strong currents.
The depth of seagrass is usually controlled by the availability of light for photosynthesis.
Seagrasses reproduce through both sexual and asexual methods.
Important seagrasses: Sea Cow Grass, Thready Seagrass, Needle Seagrass, Flat-tipped Seagrass, etc.
In India, Seagrasses occur all along the coastal areas of India and are abundant in the Palk Strait and Gulf of Mannar in Tamil Nadu.
