Anale zachte stralen: 167 - 195. Unique among species of Steatogenys in having very large maximum body size (length to end of anal fin 32 cm); distinct round or oval spot on pectoral-fin base, approximately 1.5 eye widths in diameter; irregular dark blotches on pectoral fin forming a distinct mottled pattern; 15 pectoral-fin rays; relatively many scales over lateral (8-10); relatively many pored lateral line scales to end of anal fin (97-103); relatively few bands on body (6-7) and relatively short caudal appendage in intact specimens (11.4-29.6% TL) (Ref. 51263).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00145 - 0.00994), b=3.06 (2.83 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100).
