Seagrass meadows providing food, shelter and nursery grounds and thus eccential coastal ecosystem services. With less than 4% total coverage of the sea surface area, they are estimated to contribute to almost 50% of all carbon deposition in the ocean (Duarte, Middelburg, & Caraco, 2005, Krause-Jensen & Duarte, 2016). Of these, nine species are considered critically endangered, including spiny dogfish (Squalus acanthias), European eel (Anguilla anguilla), common guillemot (Uria aalge) and bowhead whale (Balaena mysticetus).
