Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 8 - 13; Anal spines: 0; Anal soft rays: 15 - 25; Vertebrae: 44 - 51. Body slender and compressed. Anal fin base long and about twice the length of dorsal fin base. Eye diameter about twice snout length. Upper end of gill slit reaching above midline of side of body. No knob-like process in interorbital space. Dorsoposterior edge of operculum not curved inward. Traces of detached scales black. Color black or dark brown; bluish black on head and ventral surfaces, and on peritoneum (Ref. 6885).

Biology     Glossary (e.g. epibenthic)

Does not undertake a diurnal, vertical migration. Feeds heavily on crustaceans (Ref. 4525). Oviparous, with planktonic eggs and larvae (Ref. 35604). Minimum cdepth from Ref. 028981.

Estimates based on models

Preferred temperature (Ref. 115969): 0.4 - 5.2, mean 3.2 (based on 91 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00458 - 0.01316), b=3.07 (2.92 - 3.22), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.42 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (K=0.14 (very tentative estimate)).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (52 of 100).
