Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 5; Rückenflossenweichstrahlen (insgesamt) : 23; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 19 - 20. This species is distinguished from its congeners by the following set of characters: D V,23 with spines larger posteriorly; A I,19-20 (modally 19); pectoral-fin rays 18; lateral-line scales 60-61, median predorsal scales 9-10; opercular spines 2; moderate eye with eye/head length as 36.1-38.8% (mean 37.7%); mouth somewhat large with mouth/head length 34.7-35.2% (mean 35.1%); mandibular pores 3+2+3. Colouration: body with dorsally 2/3 region generally creamy yellow and about 11-12 crossing yellow stripes below mid-lateral body; spiny dorsal fin region is pale; upper jaw mostly yellow; pectoral fin with a cluster of black marks dorsally; caudal fin uniformly yellow in lower half with about 4 vertical yellow lines, its upper base bears a large deep black blotch (Ref. 94988).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00314 - 0.01524), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±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.
