Dorsal spines (total): 0; Dorsal soft rays (total): 47; Anal spines: 0; Anal soft rays: 32 - 34. Caudal fin narrow, gently rounded (Ref. 6885). Brown on the dorsal surface with dark markings, lighter ventrally with yellow to orange streaks; yellow on head in some areas and yellow mottling on fins; black blotch on anterior part of dorsal fin for first 3 to 5 rays, conspicuous; pelvic fins dusky and some dark marks on other fins; eyes reputed to be blue (Ref. 6885).

Biology     Glossary (e.g. epibenthic)

Adults are found offshore on soft bottoms (Ref. 2850); and deeper (to 300 m) than other ronquils (Ref. 48889). Reaches more than 38 cm (Ref. 48889).

Estimates based on models

Preferred temperature (Ref. 115969): 0.4 - 6.8, mean 2.9 (based on 881 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5703   [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):  3.8   ±0.3 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=9).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
