Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9 - 11; Dorsal soft rays (total): 15 - 18; Anal spines: 0; Anal soft rays: 13 - 15. Caudal fin fanned out, bluntly rounded; pelvic fins small, extending about one-third distance to anal origin (Ref. 6885). Color olive green to light brown on dorsal surface, creamy yellow to light brown on ventral surface, 4 dark saddles across back, bars of dark blotches on all fins except pelvic and anal fins; sometimes dusky along margin of anal fin; males sometimes variously blotched with orange to red; silvery areas anterior to and behind base of pectorals (Ref. 6885).

Biology     Glossary (e.g. epibenthic)

Estimates based on models

Preferred temperature (Ref. 123201): 5.9 - 8.8, mean 7.1 °C (based on 53 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.56 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
