Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7 - 9; Dorsal soft rays (total): 11 - 12; Anal soft rays: 11 - 12. This species is distinguished by having the following characters: absence of scales on the nape, prepectoral area, breast, or interpelvic area; long and strong cleithral spine (16-29 % SL), P1 12+3; a slight indication of possible hyperostosis of the first infraorbital bone and cleithral spine (Ref. 91768).

Biology     Glossary (e.g. epibenthic)

A rare (Ref. 9771), benthic (Ref. 75154) species that inhabits continental shelves and insular areas.

Estimates based on models

Preferred temperature (Ref. 123201): 13.5 - 26.8, mean 20.7 °C (based on 592 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00515 - 0.03077), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
