Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9; ऐनल सौफट रेज़: 23 - 27; जानवरों की रीड़ का जोड़: 29. This species is distinguished from its congeners, except T. rarus, by the number of scale rows between lateral line and pelvic fin origin 4.5-5.5 (vs. 3.5 scale rows); differs from T. rarus by the longitudinal dark stripes on the trunk which is absent (vs. present); differs from T. anostomus, T. denticulatus, T. kuluene, T. juruena by the principal teeth in dentary 4 (vs. 5-6) with larger and more robust teeth (vs. thinner and sharper teeth); differs from T. anostomus, T. kuluene by the conspicuous humeral marks 2 (vs. 1 and inconspicuous); differs from T. anostomus by the mouth being terminal (vs. subsuperior); differs from T. anostomus, T. araguaiensis with gill rakers on the lower limb of the first gill arch 10-12 (vs. 17-20) and upper limb 7-8 (vs. 10-12); differs from T. argenteus by the predorsal scales 8 (vs. 11-17), and from T. carvalhoi by having a rounded dark mark on the caudal peduncle (vs. a lozenge-shaped); differs from T. ommatus by teeth on maxilla 1-4 (vs. 7-8) and with a dark mark centered on caudal peduncle (vs. mark limited to the posterior portion of the caudal peduncle) (Ref. 124043).

Occupies the counter current zones of rivers where it hides under the rocks. It is constantly on the look out for food items that fall into the water (Ref. 12225).
