Actinopterygii (ray-finned fishes) > Aulopiformes
(Grinners) > Paralepididae
Etymology: Magnisudis: Latin, magnus = large + Latin, sudis = esox, fish of the Rhine, cited by Plinius 9.15; it also means "stake" (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 1000 m (Ref. 4056), usually 300 - 800 m. Deep-water; 20°S - 60°S
Probably circumglobal in the Southern Ocean from about 20°S to Antarctica. Specimens south of the Antarctic Convergence probably expatriated.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 55.0 cm TL male/unsexed; (Ref. 4056)
Vertically, juveniles occur from near surface to about 200 m and adults down to 1,000 m but mainly between 300-800 m. Feeds mainly on fishes.
