Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 12; Rückenflossenweichstrahlen (insgesamt) : 9; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 6. This species is distinguished by the following characters: A II,6; dorsal-fin spines are rigid; relatively short snout, its length 12.3-17.2% (mean 15.1%) of SL, and is shorter than postorbital length; posterior margin of the maxilla reaching beyond vertical through middle of pupil; the distance between tips of lateral lacrimal and first suborbital spines is shorter than between tips of first and second suborbital spines; no supplemental preopercular spine; tentacles on supraocular and posterior lacrimal spines are well developed, their lengths greater than orbit diameter; trunk and fins with numerous tentacles; lateral lacrimal and suborbital spines poorly are developed, indistinct, usually tiny spines and often bony protuberances without pointed tips; without the distinct black blotch on soft-rayed portion of dorsal fin (Ref. 106976).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.00606 - 0.02615), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
