Increasing knowledge of biodiversity on the Orphan Seamount: a new species of Tedania (Tedaniopsis) Dendy, 1924

A new Tedania species (Porifera) was collect using remotely operated vehicles during the Canadian mission HUD2010-029 and the British RRS Discovery Cruise DY081, on the Orphan Seamount near the Orphan Knoll, northwest Atlantic, between 2999.88 and 3450.4 m depth. Orphan Knoll is an isolated, drowned...
