Dorsal spines (total): 11; Dorsal soft rays (total): 14-15; Anal spines: 3; Anal soft rays: 9. Distinguished by the following characteristics: juveniles greyish brown to dark brown body color with 8 vertical series of white spots on body; adults dark brown with less distinct vertical series of white spots and obscured by numerous additional pale spots and blotches of variable size; fins mostly unspotted; depth of body contained 2.3-2.7 times in SL, width 2.0-2.5 times in depth; head length 2.3-2.5 times in SL; convex interorbital area, width subequal to eye diameter for fish 10-20cm SL; subangular preopercle, 3-5 enlarged serrae at angle; fleshy ventral edge of preopercle, without serrae; smooth edge of interopercle and subopercle or with a few serrae; convex upper edge of operculum; ovate and enlarged posterior nostrils of adults, larger than anterior nostrils (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Occurs in deep waters (Ref. 7364). Benthic and benthopelagic (Ref. 58302). Feeds mainly on fish and crustaceans (Ref. 89707). A good fish to eat, fleshy, eaten any way except raw (Ref. 7364). Minimum depth from Ref. 122680.

Estimates based on models

Preferred temperature (Ref. 123201): 9.3 - 15.3, mean 15.1 °C (based on 3 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00826 - 0.02530), b=3.05 (2.90 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.67 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
