Community structure of pelagic cnidarians off Adélie Land, East Antarctica, during austral summer 2008
21 pages, 8 figures, 4 tables Some studies have suggested that pelagic cnidarians are important components of the Southern Ocean ecosystem due to their high abundance and diversity and their high predatory effects, although little information on these animals is available. Thus, we examined the spat...
