Size / Weight / Age

Max length : 52.0 cm SL male/unsexed; (Ref. 6181); common length : 35.0 cm SL male/unsexed; (Ref. 6181)

Environment

Marine; bathypelagic; depth range 0 - 2830 m (Ref. 6181)

Climate / Range

Deep-water; 31°S - 79°S, 180°W - 180°E (Ref. 6181)

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.

Short description

Dorsal spines (total): 36 - 39; Dorsal soft rays (total): 24-34; Anal spines: 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     Glossary (e.g. 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.

IUCN Red List Status (Ref. 115185)
