Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 5 - 8; Dorsal soft rays (total): 6 - 7; Anal spines: 0; Anal soft rays: 6 - 8. Dorsal fins moderately developed and placed fairly close together; caudal rounded; anal originating below interspace between dorsal fin, closer to first; lower 4 or 5 rays of pectorals greatly exserted and thickened; pelvic fins reduced (Ref. 6885). Olive brown on dorsal surface, paler below; 5 or 6 dark brown saddle-like markings on back and sides; dark brown to dusky on dorsal, caudal and pectoral fins; pelvic and anal fins pale (Ref. 6885).

Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 7.9, mean 5.9 °C (based on 32 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
