Taxonomic Remarks
Validity of species questionnable for some authors, but no recent publications.
पर्यावरण: पर्यावरण / जलवायु क्षेत्र / गहराई सीमा / वितरण सीमा
पारिस्थितिकी
समुद्री बैथीपिलाजिक; गहराई सीमा 0 - 2830 m (Ref. 6181). Deep-water; 31°S - 79°S, 180°W - 180°E (Ref. 6181)
Southern Ocean: circumpolar. In the belief that there was only a single species of Paradiplospinus, many authors used the name Paradiplospinus gracilis as including Paradiplospinus antarcticus.

Body shape (shape guide): elongated; Cross section: compressed.
Adults and subadults epipelagic to mesopelagic, or mesobenthopelagic at shelves and slopes from surface to 830 m (temp. 0° to 4°C). Larvae and juveniles, probably mesopelagic to bathypelagic, down to 2,830 m depth (Ref. 5084). Feeds on krill, squid and fishes (predominantly myctophids). Larval and juvenile specimens mostly obtained between southern land masses and the Antarctic continent.
