Short description Identification keys | Morphology | Morphometrics
Vertebrae: 120 - 123. This species is distinguished from S. mitsukurii by the following characters: colour of body brown dorsally; caudal fin with ventral and dorsal tips markedly tapered and broadly white; dermal denticles uniscuspidate and lanceolate; larger number of vertebrae, precaudal 91-94, total 120-123 (vs. body dark grey to black; caudal fin with ventral and dorsal tips rounded and not white in colour; denticles tricuspidate and rhomboid; precaudal 86-90 and total 116-117 S. mitsukurii) (Ref. 122378).
Found in shallow waters of the upper continental slope (Ref. 122378).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00165 - 0.00730), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.3 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100).
