part of ocean floor sea floor sea grass bed "Seagrass beds are highly diverse and productive ecosystems, and can harbor hundreds of associated species from all phyla, for example juvenile and adult fish, epiphytic and free-living macroalgae and microalgae, mollusks, bristle worms, and nematodes. Few species were originally considered to feed directly on seagrass leaves (partly because of their low nutritional content), but scientific reviews and improved working methods have shown that seagrass herbivory is a highly important link in the food chain, with hundreds of species feeding on seagrasses worldwide, including green turtles, dugongs, manatees, fish, geese, swans, sea urchins and crabs." https://en.wikipedia.org/wiki/Seagrass 2016-01-18 ORCID:0000-0002-4366-3088 seagrass bed A bed of a marine, saline water body which is covered by one or more speices of seagrass typically belonging to the families Posidoniaceae, Zosteraceae, Hydrocharitaceae, or Cymodoceaceae. 2010-03-16T12:12:30Z seagrass meadow marine bed
