背的軟條 (總數): 5; 臀鰭軟條: 68 - 73; 脊椎骨: 63 - 65.

生物學特性     字彙 (例如 epibenthic)

Adults feed strictly on fishes. Enters the flooded forest during high water and stays near the edge of the forest during low water (Ref. 9497). Migrates into smaller streams to spawn (Ref. 37770). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).

成魚嚴格地以魚為食。 卵生的, 明顯的成對可能地像其他的相同該科的成員.(參考文獻 205)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00278 - 0.01137), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.5   ±0.80 se; based on food items.
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Assuming Fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
