Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 4; Raggi dorsali molli (totale) : 8 - 12; Spine anali: 3; Raggi anali molli: 5 - 8. Mouth is terminal and upturned. Normally has 12-14 vertical bars along the body, alternating with iridescent interbars of approximately equal width. Sympatric species have head scales or humeral spots and ocular bars.

Are generally cryptic or solitary (Ref. 58006). Inhabit heavily vegetated creeks, sloughs and roadside ditches. Feed on microcrustaceans and other small, benthic invertebrates (Ref. 58006). Oviparous, eggs are found in vegetation or just on the substrate (Ref. 58006).

Eggs are guarded by the male (Ref. 58006).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.43 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (tm=1; tmax=1.5; Fec=76).

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

Price category (Ref. 80766): Unknown.
