Short description Morfología | Morfometría

Radios blandos dorsales (total): 10; Radios blandos anales: 14 - 15; Vértebra: 39 - 41. It differs from Creagrutus amoenus and Creagrutus kunturus in its lack of the series of dark midlateral spots on the body that progressively coalesce ontogenetically to sometimes form a midlateral stripe in adults of the latter two species and in the distance from the snout to the anal fin origin (27.2-30.7 vs 33.8-38.8 and 30.8-34.0, respectively), distance from the snout to the pelvic fin insertion (22.2-25.6 vs 29.0-35.6 and 27.9-31.6, respectively), and the caudal peduncle depth (8.9-9.8 vs. 12.2-13.8 and 11.1-12.1, respectively). It further differs from Creagrutus amoenus in the number of vertebrae (39-41 with 39 in four specimens and 40 or 41 in 10 specimens vs 35-39 with 36-38 in 34 specimens and 39 in only one of 36 radiographed specimens, respectively, and from Creagrutus kunturus in the number of median predorsal scales (9 or 10 vs 12, respectively).

Biología     Glosario (por ej. epibenthic)

Occurs along the edge of a large pool immediately below a small fall preceded upstream by a long series of rapids and in a clear water stream with sandy bottom (Ref. 52414). Observed swimming close to the substrate in small schools of four to six fish (Ref. 52414). Feeds on benthic aquatic insect larvae (Ref. 52414).
