Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 11; Spine anali: 3 - 4; Raggi anali molli: 40 - 45; Vertebre: 38. The presence of a long thin and up-turned process on the posterosuperior region of the rhinosphenoid is autapomorphic for this species.

Inhabits swamps or marshes of the lower reaches of rivers (Ref. 26543).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01202 (0.00470 - 0.03074), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
