Latitudinal distribution of pelagic ostracods (Myodocopa) in the Australian-New Zealand sector of the South Ocean
Data of Russian surveys in the Australian-New Zealand sector of the South Ocean in 1956-1983 are presented. Fauna of ostracods in this region includes 66 species belonged to 35 genera, 4 subfamilies and 2 families that is more than in the Atlantic and Indian sectors of the South Ocean but less than...
