Short description Morphology | Morphometrics

Dorsal soft rays (total): 116-123; Anal spines: 2; Anal soft rays: 74 - 87; Vertebrae: 125 - 129. Body very elongate and compressed. Head profile straight or scarcely convex, with sagittal crest strongly elevated. Both jaws have a short dermal process; the lower jaw longer than the upper jaw. The dorsal fin has a few weak anterior spines that hardly differ from the soft rays. Body color silvery, dorsal fin membrane black before the third to the fourth soft ray.

Biology     Glossary (e.g. epibenthic)

Probably benthopelagic from 150 to 400 m, juveniles epipelagic or mesopelagic. Feeds on fishes (including Engraulis mordax and Merluccius productus off California) and squids. Occasionally hooked, captured in nets, or found washed ashore. No special fishery.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00076 (0.00034 - 0.00169), b=3.09 (2.89 - 3.29), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.69 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100) .
Price category (Ref. 80766):   Medium.
