Etymology: Ptychochromis: Greek, ptyx, = fold + Greek, chromis = a fish, perhaps a perch (Ref. 45335); curvidens: Specific name comes from the Latin, curvus, a 'curve', and dens, a 'tooth', in reference to the apomorphically recurved oral jaw dentition characteristic for this species (Ref. 57663).

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 14; Raggi dorsali molli (totale) : 11 - 12; Spine anali: 3; Raggi anali molli: 9; Vertebre: 27 - 28. It is distinguished from all congeners by the presence of a characteristically robust and strongly recurved oral dentition (Ref. 57663). An extremely deep-bodied and robust species, rather less laterally compressed than other members of the genus (Ref. 57663). Coloration in life: body dark golden-green dorsal of midline, and bright, iridescent golden below; no distinctive lateral markings; unpaired fins dusky charcoal gray, membranes grayish to hyaline, pelvic fins hyaline proximal to base, blackish distally, and pectoral fins bright yellowish-orange (Ref. 57663). Ground coloration in preservative is dark brownish-green

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 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).
