Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 79 - 92; Anal spines: 0; Anal soft rays: 65 - 72; Vertebrae: 38 - 39. Caudal fin double truncate (Ref. 27363). Almost wholly ambicolorate, the blind side is darkly pigmented except for the anterior portion of the body which has dark pigments only on the opercle, subopercle, a small region adjacent and dorsal to the head, and the distal half of the pectoral fin; two lighter pigmented areas were present on the unpigmented dorsal region of the head. The blind side had one of the 3 typical ocelli (upper one) in the same position with that of the ocular side (Ref. 34245).

Biology     Glossary (e.g. epibenthic)

Prefers hard or sandy substrates, rarely on mud (Ref. 43588). Feeds on fishes and cephalopods (Ref. 36453).

Estimates based on models

Preferred temperature (Ref. 123201): 4.6 - 10.1, mean 7.9 °C (based on 82 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00270 - 0.00849), b=3.19 (3.04 - 3.34), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.53 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
