This image shows a seagrass bed in the Geograph Bay Marine Park, captured from a BRUVS survey. The seagrass beds of Geographe Bay are one of the largest meadows recorded in Australia, extending into water depths of up to 50 metres. Globally, seagrasses are believed to be the third most valuable ecosystem in the world. Seagrass beds prevent erosion of the sea bottom, reduce carbon dioxide out of the atmosphere and support diverse communities of marine animals such as invertebrates, fish, crabs, turtles, mammals and birds by providing food and shelter. Seagrasses enhance overall marine biodiversity and provide ecological functions and a variety of services to humans.
