Sponges were well represented during the first dive of the 2021 North Atlantic Stepping Stones expedition, including this large, plate-like demosponge seen at 2,423 meters (7,950 feet) depth that may represent a potential species range extension. Rossellid and farreid glass sponges as well as several unknown species of sponges were also observed.
