Etymology: Somniosus: Latin for sleepy, reflecting Lesueur’s surmise that these sharks are slow or sluggish because of their relatively small fins (hence the name sleeper sharks). (See ETYFish);  antarcticus: -icus (L.), belonging to: the Antarctic (Whitley presumed this to be the first shark recorded from there). (See ETYFish).

जानवरों की रीड़ का जोड़: 36 - 38. Somniosus antarcticus differs from S. pacificus by the following characters: interdorsal space about 80% of prebranchial length (vs. 70%); height of first dorsal fin about 3.0% of precaudal length (PCL) (vs. 3.7%); height of second dorsal fin about 2.9% of PCL (vs. 3.4%); number of turns in spiral valve 36-41 (mode 39) (vs. 32-37, mode 33); precaudal vertebrae 30-31 (mode 30) (vs. 28-30, mode 29) (Ref. 50224).

Estimates based on models

Preferred temperature (Ref. 123201): 1.7 - 5.8, mean 4 °C (based on 113 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00168 - 0.00901), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.58 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
