Etymology: Creagrutus: Greek, kreagreytos, -os, -on = to tear, to rip up the flesh (Ref. 45335);  cerritulus: From the Latin cerritulus, meaning strange, in reference to the intense modifications of representatives of this species relative both to the other species of Creagrutus and across the Stevardiinae and even the Characidae..

Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 10; Raggi anali molli: 13 - 15; Vertebre: 36 - 37. Creagrutus cerritulus can be easily distinguished from all congeners by the following unique characters: mouth distinctly ventrally positioned; dentary and premaxilla dentition strongly spatulate with the central and adjacent cusps of similar size; anterior portion of the dentary strongly bent forming a nearly 120° angle relative to the posterior portion of the lower jaw and resulting in the cutting edges of the dentary teeth running parallel to the distal axis of the jaw; symphyseal interdigitations present on the lingual surface between the contralateral premaxillae; a notch along the posterior margin of the maxilla present which serves for the insertion of the ligamentum primordiale; distal tips of the mesethmoid wings anteriorly bent; very tight association between the posterior, cuneiform process of the vomer and the anterior portion of the parasphenoid; intestine distinctly elongated; size of stomach reduced; and swimbladder reduced, especially the posterior chamber (Ref. 116020).

Biologia     Glossario (es. epibenthic)

Inhabits river characterized by moderate to strong currents over a substrate composed primarily of pebbles and rocks. The water was reddish in color, alkaline, with high conductivity (10000 μS/cm) and 'very salty' water. Collected along with only six other fish species.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00653 - 0.03348), b=2.96 (2.77 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.5   ±0.1 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).
