Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 20 - 21; Rayons mous dorsaux (Total) : 7 - 8; Épines anales: 3; Rayons mous anaux: 6 - 7; Vertèbres: 28 - 29. Diagnosis: relatively deep-bodied species with a steep, straight forehead (Ref. 42983, 52307) and short snout (Ref. 52307). Very flat gibbosity, most pronounced in adult males; lower pharyngeal bone with 151 teeth (mean value); usually 5 broad gill rakers on lower limb of first arch (Ref. 42983).
Inhabits clear flowing water with rocks, in river pools; found in small groups, up to 20 individuals (Ref. 42983). Likely a pair-bonding, cave-spawning species (Ref. 52307).
