Also, the help keeping the water clear and it provides wave protection and protection for coastal erosion. Sea grasses are the only flowering plant in the sea. There are a lot of species of seagrasses however while there are over 500 species of algae, there are only 15 species of seagrasses on the Great Barrier Reef. -->Sometimes, there are different colors of seagrasses.

The color of the seagrass probably changes depending on the situation. In order for it to be at its normal color, it most likely needs a certain amount of water and sunlight. If there is an extra large amount of sunlight, then it might be a different shade of its color and also when it recieves an extra small amount of sunlight.
