Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10-11; Anal spines: 0; Anal soft rays: 8 - 10. Body slightly compressed. The head is small; eyes large, diameter greater than snout length. Color is yellow-fawn, with irregular oblique brown blotches on the sides. The operculum is silver-black; anus and gill cavity black; belly stippled black; caudal fin base and inner ventral fin rays black.

Biology     Glossary (e.g. epibenthic)

Found on the continental shelf and upper slope over mud and clay bottom. Catch data indicate a schooling habit. Feeds mainly on bottom-living invertebrates. Also known to feed on pelagic crustaceans like euphausiids, decapods and mysids (Ref. 27637). A hermaphroditic species. Marketed fresh and sometimes made into fishmeal (Ref. 6688). Young are pelagic, living near the surface, the adults are demersal, living between 50 and 1000 m depth (Ref. 47377).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00285 - 0.00582), b=3.13 (3.03 - 3.23), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=3-4).
Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100) .
Price category (Ref. 80766):   Unknown.
