Validity of species questionnable for some authors, but no recent publications.

Environment: milieu / climate zone / depth range / distribution range Ecología

; marino batipelágico; rango de profundidad 0 - 2830 m (Ref. 6181).   Deep-water; 31°S - 79°S, 180°W - 180°E (Ref. 6181)

Distribución Países | Áreas FAO | Ecosistemas | Ocurrencias, apariciones | Point map | Introducciones | Faunafri

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.

Biología     Glosario (por ej. epibenthic)

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.
