Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 29.2 cm SL mannelijk / geslacht onbekend; (Ref. 81642)
Dorsale stekels (totaal) : 2. Diagnosis: caudal peduncle relatively long, its depth slightly larger than the horizontal distance between the adipose and caudal fin bases (never twice as large); anterior edge of pectoral spine smooth, except for a few serrations distally; preorbital head length greater than maximum head depth (measured to end of supraoccipital process), lending the snout an elongate appearance; interorbital distance 22-25% HL; orbital diameter maximally 2 times in interorbital distance; numerous small spots on body and fins; spots on head usually smaller than those on flanks (Ref. 81642).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00218 - 0.01265), b=3.09 (2.88 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
