Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 57 - 67; Rückenflossenweichstrahlen (insgesamt) : 0; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 40 - 44. Caudal long, narrow, bluntly pointed; pectorals broad and rounded (Ref. 6885). Light brown on dorsal surfaces, lighter ventrally; about 10 to 12 white vertical bars edged with brown in a series on upper part of body, spreading or dividing to become confluent with pale ventral coloring; small brown smudges at bases of membranes between spines of posterior part of dorsal fin (Ref. 6885).

Inhabits sandy to rocky bottoms at depths of 46 to 128 meters (Ref. 51666).

Estimates based on models

Preferred temperature (Ref. 123201): 1.3 - 8.8, mean 4.9 °C (based on 133 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00148 - 0.00852), b=2.95 (2.74 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
