Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 10; Rückenflossenweichstrahlen (insgesamt): 10-12; Afterflossenstacheln 3; Afterflossenweichstrahlen: 10. Distinguished from its congeners by the following set of characters: D X,11; A III,10; total gill rakers on first arch 23-26, mode 24 (upper limb 6-9, lower 16-18); lateral-line scales 31-37, mode 33; body scales above pectoral fin with about 11-40 spinules on posterior margin, the number increasing with growth up to ca. 20 cm SL; rounded caudal fin in young and adults; colour of posterior soft portions of vertical fins hyaline reddish with black margins, width about 1/4 of pupil diameter in fresh specimens (usually distinct in preservation); 5 white or pale relatively narrow vertical bands on body, the third around 1/4-2/5 width of pupil, somewhat expanded dorsally and ventrally, and relatively vertical throughout, including dorsal and ventral extremities (Ref. 94109).

Estimates based on models

Preferred temperature (Ref. 115969): 16.3 - 27.1, mean 23.9 °C (based on 108 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.00959 - 0.05474), b=2.93 (2.72 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±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.).
Verwundbarkeit (Ref. 59153):  Low vulnerability (23 of 100) .
