Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 16 - 17; Mjukstrålar i ryggfenan (totalt): 10-11; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 8 - 10; Ryggkotor: 29 - 31. Diagnosis: 19-23 rakers on lower limb of first arch (Ref. 81260). Length of lower pharyngeal jaw 40-50% of head length (Ref. 81260), width 34.5-38.0 (Ref. 2). Pearly yellow in life, with no markings on body; preserved specimens dark grey on back, with a horizontal darker band in some; decurved snout (Ref. 2).

Biologi     Ordlista (t.ex. epibenthic)

Seems to prefer shallow areas near the edges of the lake (Ref. 52307). Occurs in schools at the surface; stomach of specimens which were examined contained organic debris; benthic and epilithic diatoms, and sponge spicules were nearly always present and many had inorganic particles in the stomach; individuals were seen shoveling sand into the mouth, moving it about in the buccopharynx, then spitting out the sand and making swallowing movements (Ref. 2). Lacks marked sexual dichromatism when sexually active (Ref. 81260). Probably a biparental ovophilic mouthbrooder that forms little to no (Ref. 52307) and only temporary pair bonds (Ref. 81260).
