Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 33 - 42; Duri dubur: 0; Sirip dubur lunak: 18 - 24. Snout short, bluntly V-shaped, not upturned at tip. Barbels short (Ref. 7251). Absence of fontanelle and post dorsal shields. Single row of pre anal shields, 6-11 (Ref. 4639). Dorsal shields 7-13, lateral shields 22-34 (Ref. 4639). Blackish viscera (Ref. 37032). Head and back dark, lower surface white (Ref. 37032). Anal fin origin beneath dorsal fin origin (Ref. 86798).

Inhabit river mouths, lakes, estuaries, and bays; occasionally enters the open sea.

Estimates based on models

Preferred temperature (Ref. 123201): 7.5 - 25.5, mean 15.6 °C (based on 138 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.39 se; based on food items.

Daya lenting (Ref. 120179): sangat rendah, Waktu penggandaan populasi minimum lebih dari 14 tahun (K=0.04; tm=14-17; tmax=67; Fec=48,000).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (86 of 100).

kategori harga (Ref. 80766): Unknown.
