Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 2; Raggi dorsali molli (totale) : 7; Raggi anali molli: 12 - 13; Vertebre: 44 - 45. Distinguished from its congeners by the following unique combination of characters: head length 32.7-33.5% SL, head depth 14.2-15.3% SL, depth of caudal peduncle 7.5-8.8% SL, eye diameter 11.9-12.3% HL, a pattern of dark dots arranged in vertical columns on the sides of the body, a convex snout and a broad, shallowly incised humeral process (Ref. 41209).

Inhabits rivers and ponds in plains and submontane regions (Ref. 41236). It is usually dug out from the bottom of ponds where they lie buried in soft, wet clay.

Estimates based on models

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

Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).
