Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 17; Rückenflossenweichstrahlen (insgesamt): 11-12; Afterflossenstacheln 3; Afterflossenweichstrahlen: 7 - 8; Wirbelzahl: 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).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00793 - 0.04175), b=3.02 (2.84 - 3.20), 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
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Verwundbarkeit (Ref. 59153):  Low vulnerability (23 of 100) .
