These are mostly within the Antarctic Circle and include the Ross Sea, the Weddell Sea, the Davis Sea, McMurdo Sound and the Southern Ocean. Although it is commonly found at depths of less than 100 metres (330 ft), remotely operated underwater vehicles armed with lights and cameras have recorded the scallop at much greater depths, including one ...
