Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 17; Radios blandos dorsales (total) : 11 - 12; Espinas anales: 3; Radios blandos anales: 7 - 8; Vértebra: 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).

Biología     Glosario (por ej. epibenthic)

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).

Bayesian length-weight: a=0.01950 (0.00850 - 0.04473), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  2.3   ±0.1 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
