Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 5 - 9; Rückenflossenweichstrahlen (insgesamt) : 14 - 19; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 10 - 14. Two-spotted first dorsal fin; chin uniformly pigmented; dossal saddles moderate to wide; incomplete lateral line; preopercular spines slight to moderate, palatine teeth weak to moderate, and postpectoral prickling slight to moderate.

Estimates based on models

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

Bayesian length-weight: a=0.00794 (0.00389 - 0.01621), b=3.12 (2.95 - 3.29), 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): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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