Seagrasses are flowering plants that live in the sea. They have grass-like leaves and roots that hold them in the sand. They live in shallow seas or the intertidal zone. Their water must remain clear so they can receive enough sunlight.
Not many marine creatures eat seagrass, but many marine animals make the seagrass meadows their home.
Seagrass meadows can have many more types of animals than the areas nearby with no seagrass.
Some beaches become covered in very thick mats of dead seagrass. This is common after storms. Motor boats riding through sea grass meadows can cut it up.
