Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 160 - 163; Épines anales: 0. Snout short, blunt, with large terminal and lateral angle scutes; underside of the snout, mandible and most of the suborbital, and part of the lower margin of the preopercle without scales. Pyloric caeca 22 to 32. Body scales with sharp, needle-like spinules arranged in parallel rows. Overall color is brownish, abdominal region violaceous; gill membranes blackish; fins dusky, first dorsal fin blackish distally. Also Ref. 2800.

A benthic species found on the continental slope (Ref. 75154). Off Hawaii, individuals reportedly taken in June by the ALBATROSS had been feeding exclusively on small eggs. Mature eggs were found in a specimen taken in August (Ref. 1690).

Estimates based on models

Preferred temperature (Ref. 123201): 7.9 - 13.8, mean 10.1 °C (based on 323 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.1 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
