Short description Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. Snout long and sharply pointed, its anterolateral margin almost completely supported by bone; head ridges strong and coarsely spined; the dorsal surfaces of the head completely scaled except for the nasal fossa, scales atop head with spinules set in divergent rows; the underside of the head naked except for small isolated scales above the angle of the mouth and below the end of the opercle ridge in some specimens; swarthy to brownish, ventrally darker on the belly, with no prominent markings; the mouth and gill cavities blackish; the first dorsal fin uniformly dusky (Ref. 1371).

Biology     Glossary (e.g. epibenthic)

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=0.00219 (0.00097 - 0.00495), b=3.17 (2.98 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.48 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (55 of 100) .
Price category (Ref. 80766):   Medium.
