Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 14 - 17; Anal soft rays: 4. This species is distinguished by the following characters: D 14-17; subdorsal rings 2+1-2; tail rings 33-34; nose profile straight with a small spine; head and body spines small and blunt, proportionally small in largest specimen; most trunk ridges are with low tubercles; upper shoulder-ring spine is just below gill opening; lower shoulder-ring spine thick, knoblike, single or double with less developed secondary spine anteriorly; neck ridge is short and distinctly raised above gill openings (Ref. 123057).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Trophic level (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
