Family:  Gempylidae (Snake mackerels)
Max. size:  52 cm SL (male/unsexed)
Environment:  bathypelagic; depth range 0 - 2830 m
Distribution:  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.
Diagnosis:  Dorsal spines (total): 36-39; Dorsal soft rays (total): 24-34; Anal spines: 2-2; Anal soft rays: 25-31; Vertebrae: 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.
Biology:  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.
IUCN Red List Status: Not Evaluated (Ref. 115185)
