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.

Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 36 - 39; Mjukstrålar i ryggfenan (totalt): 24-34; Taggstrålar i analfenan 2; Mjukstrålar i analfenan: 25 - 31; Ryggkotor: 64 - 67. Body is extremely elongate. Mouth with fang-like teeth, 3-6 fangs anteriorly in upper jaw and 1 fang on each side of the lower jaw. Pyloric caeca 6. Color is silvery white without any conspicuous marks except 40 - 50 narrow longitudinal lines of pale melanophores; the dorsal-fin base, opercular region and caudal-fin origin dark brownish.

Biologi     Ordlista (t.ex. 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.
