Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 13 - 14; Rückenflossenweichstrahlen (insgesamt) : 9 - 11; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7 - 9; Wirbelzahl: 28. This species is distinguished from all congeners by the following characters: bright yellow color pattern of the unpaired fins (vs. mostly red in other species); covered with white dots aligned between rays; distal border of the dorsal fin and dorsal and ventral contours of caudal fin red with thin light stripes; prominent adipose hump in mature males, extending dorsally above the tip of the longest dorsal-fin spines (vs. less developed) (Ref. 118066).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00849 - 0.04084), b=3.01 (2.83 - 3.19), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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).
