Gastropod: A ew species of gastropod that lives on the seafloor of the Antarctic deep sea. The shell and the snail within it can be seen through a layer of mantle tissue that protects the shell. Altough living in the dark, this species has developed eyes Photograph: British Antarctic Survey

Carniverous moonsnail: This carnivorous moonsnail lives in the Antarctic deep sea. It can detect food from a wide distance. Polyps, covering its shell, use the moonsnail as transport to food sources Photograph: British Antarctic Survey

Amphiod crustacean: The crustacean family Epimeriidae have successfully developed new species in Antarctica. This pink species is new to sciences and the first deep sea member of this group Photograph: British Antarctic Survey

Giant amphipod: Most of the deep-sea crustaceans are less than 1 cm in size, but this species of Paraceradocus can reach more than 5 cm in length. The white colour is an adaptation to the deep sea as related species from the Antarctic shallow waters are bright red Photograph: British Antarctic Survey

RV Polarstern in Marguerite Bay. The three expeditions aboard the Polarstern were part of the Antarctic benthic deep-sea biodiversity project. A team from 14 research organisations from around the world investigated the seafloor landscape to build a picture of this little known region of the ocean Photograph: German Centre for Marine Biodiversity; DZMB
