Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 2; Radios blandos dorsales (total) : 7; Espinas anales: 0; Radios blandos anales: 11 - 12; Vértebra: 43 - 44. Diagnosis: Gogo atratus is distinguished from congeners in having a longer snout, 54.8-56.4% of head length vs. 47.1-54.3%; and faintly mottled dark gray colouration vs. uniform brown, highly mottled dark gray and cream, or mottled brownish-gray (Ref. 75790). It further differs from Gogo ornatus in having a larger eye in specimens larger than 110 mm standard length, eye diameter 13.0-14.3% of head length vs. 9.2-12.5% (Ref. 75790). It differs from G. brevibarbis in having unicuspid teeth vs. bicuspid, and a smaller eye, eye diameter 13.0-14.3% of head length vs. 19.5% (Ref. 75790). It differs from G. arcuatus in having a narrower head, head width 17.8-18.9% of standard length vs. 20.8-21.0% and interorbital distance 28.9-30.5% of head length vs. 34.8-35.1%; smaller eye, eye diameter 13.0-14.3% of head length vs. 17.7-18.6%; shorter dorsal spine, 17.7-20.6% of standard length vs. 21.2-21.8%; shorter pectoral spine, 16.5-18.9% of standard length vs. 19.9-20.2%; and a straight dorsoposterior margin of the dorsal fin vs. concave (Ref. 75790).

Biología     Glosario (por ej. epibenthic)

Found over an open sand/cobble bottom interspersed with scattered rocky ourcroppings at a depth of less than 1 m; the water is clear, with the bottom consisting of either sand or rock/cobble; the bottom is lightly overlain with leaf litter in quieter stretches of the river (Ref. 75790).
