Actinopterigi (pesci con pinne raggiate) > Perciformes (Perch-likes) > Gempylidae (Snake mackerels)
Etymology: Paradiplospinus: Greek, para = the side of + Greek, diploos = double + Latin, spina, pinna = thron (Ref. 45335).   More on author: Andriashev.

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

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

; marino batipelagico; distribuzione batimetrica 0 - 2830 m (Ref. 6181).   Deep-water; 31°S - 79°S, 180°W - 180°E (Ref. 6181)

Distribuzione Stati | Aree FAO | Ecosystems | Presenze | Point map | Introduzioni | 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.

Short description Morfologia | Morfometria

Spine dorsali (totale): 36 - 39; Raggi dorsali molli (totale): 24-34; Spine anali 2; Raggi anali molli: 25 - 31; Vertebre: 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.

Biologia     Glossario (es. 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.
