Seagrass Meadows and Marsh

Explore still images

Seagrasses and seaweeds are often the dominant structure-forming organisms in shallow waters. Like terrestrial grasses and trees, these plants are primary producers, providing dissolved oxygen, food, and shelter for organisms living within the habitat. Dense seagrass meadows provide refuge from predators and tidal currents.


Seagrass is generally seasonal. Winter die-off removes the predominant structure in these habitats. During this time, benthic organisms living in these areas are more exposed to strong ocean currents and roving predators.
