Duri punggung (Keseluruhan (total)) : 1; duri punggung lunak (Keseluruhan (total)) : 6; Sirip dubur lunak: 58 - 68. Diagnosis: posterior (=inner) side of pectoral-fin spines strongly denticulate; 58-68 branched anal-fin rays; 16-18 gill rakers on lower limb of first gill arch; barbels very short, nasal barbel extending to hind margin of eye; adipose fin always present; swim bladder extending backwards through a caecal appendix to above end of anal-fin base (Ref. 43912, 57127). Palatine teeth present (Ref. 57127). Posterior nostrils closer to each other than are anterior ones; 7-9 branched pelvic fin rays (Ref. 43912).

Probably carnivorous, feeding at least partly on small crustaceans (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
