Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 19 - 20; Rückenflossenweichstrahlen (insgesamt): 15-18; Afterflossenstacheln 2; Afterflossenweichstrahlen: 12 - 13; Wirbelzahl: 34. Pectoral fin is represented by a single spine in small specimens or entirely absent in individuals over 25 cm SL. Lateral line branching below the 5th to 6th spine of the first dorsal fin. The upper line reaches to the base of the first dorsal finlet, the lower line runs sub laterally. Most of the body is naked except for a large rectangular stripe of squamation extending forward from the caudal peduncle. Overall color is grayish brown; a black blotch is on membranes between the first and third dorsal-fin spine.

Estimates based on models

Preferred temperature (Ref. 123201): 3.9 - 7.2, mean 6 °C (based on 147 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00163 - 0.00807), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.7 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):  Moderate vulnerability (36 of 100).
