Seamounts, underwater mountains rising from the ocean floor, are found in all oceans of the world and are abundant features of the seafloor. They are known to be hotspots of biological diversity and production, and are important for marine biodiversity and the status of marine food webs. Migratory fish and cetaceans rely on seamounts as well for their food supply. Limited knowledge of seamount-associated fauna to date indicates that many species grow and reproduce slowly, thus are highly vulnerable to overexploitation.
