New species of benthopelagic hydromedusae from the Weddell Sea
7 pages, 6 figures, 1 table Four medusa species were collected by an epibenthic sledge during the "Polarstern" ANT XV/3 cruise carried out from January to March 1998 in the eastern Weddell Sea. The specimens were collected in the benthic boundary layer at depths ranging between 1,583 and 2...
