A New Species of Osedax (Siboglinidae: Annelida) From Colonization Experiments in the Arctic Deep Sea
Large parcels of organic matter in the deep sea, such as whale carcasses, harbor a very specialized fauna, most famously the bone-eating worms in the genus Osedax (Annelida, Siboglinidae). Although Osedax was first described only 15 years ago, there are already 26 described species from the Pacific,...
