Etymology: Geophagus: Greek, gea = the earth + Greek, phagein = to eat (Ref. 45335); crocatus: From the Latin adjective crocatus, meaning saffron yellow, in reference to the yellow operculum on live specimens.

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 17; Raggi dorsali molli (totale) : 11 - 12; Spine anali: 3; Raggi anali molli: 7 - 8; Vertebre: 32 - 33. Differs from Geophagus grammepareius, G. taeniopareius, G. argyrostictus, G. gottwaldi and G. harreri by its incomplete suborbital stripe (vs. complete). Can be further diagnosed from G. abalios, G. brokopondo, G. surinamensis, G megasema, G camopiensis, G. altifrons, G. parnaibae, G. sveni, and G. neambi by having an incomplete suborbital stripe formed by a preopercular black mark (vs. absent). The lateral bar pattern of Geophagus crocatus distinguishes this species from all other congeners. The bar pattern is formed by 6 vertical bars on the flank, with bars 2 and 3 uniquely fused dorsally at the base of the spiny dorsal fin between spines 9 and 10. Distinguished from all members of the G. surinamensis complex with incomplete suborbital markings by the presence of 6 lateral bars (vs. absent in G. proximus and G. brachybranchus, 4 bars in G. winemilleri, and 7 bars in G. dicrozoster (Ref. 95093).

Inhabits black water river, running through thick gallery forest. Mostly found abundat in areas of sluggish water with sandy bottoms and relatively little forest cover (Ref. 95093).

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=0.02042 (0.00898 - 0.04642), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.3 ±0.1 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).
