Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 11 - 12; Anale stekels: 0; Anale zachte stralen: 11. Body except for snout, pectoral base and caudal peduncle covered with prickles; teeth fused into plates, two plates on each jaw; nostril with two openings; body dark green dorsally with six transverse black bars, white ventrally; fins dusky green or dark brown (Ref. 13608).

Solitary or in groups of 2 or 3 individuals but never in schools (Ref. 35237). Inhabits shallow inshore waters usually on soft bottoms. Frequently found in freshwater (Ref. 13608). When threatened, it becomes inflated like a balloon, in order to ward off predators. Carnivorous, feeding mainly on mollusks which crushes with its powerful teeth (Ref. 35237). Of negligible commercial importance and usually not marketed (Ref. 5217).

Estimates based on models

Preferred temperature (Ref. 123201): 25.6 - 28, mean 27.3 °C (based on 210 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02512 (0.01608 - 0.03923), b=2.86 (2.74 - 2.98), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.6 ±0.50 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).

Prijsklasse (Ref. 80766): Very high.
