Etymology: Eutropiichthys: Greek, eutropheia = well fed + Greek, ichthys = fish (Ref. 45335); cetosus: Derived from Latin adjective cetus, meaning a large sea animal (commonly referred to as whale), in allusion to the numerous gill rakers of this species, which are reminiscent of baleen in baleen whales.

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 2; شعاع نرم باله پشتي (کل) : 7; شعاع نرم باله مخرجي: 48 - 54; مهره ها: 49 - 52. Eutropiichthys cetosus is distinguished from all congeners, with the exception of E. burmannicus by the possession of more rakers 25-35 (vs. 15-20) on the first gill arch. It can be diagnosed from E. burmannicus by having moderately rounded snout in lateral view (vs. distinctly pointed in E. burmannicus) and slightly trilobed in dorsal view (vs. acutely angular in E. burmannicus), a deeper head relative to its length (68.7-77.1% HL vs. 65.4-67.5% HL), fewer branched rays on pectoral fin (13-15 vs. 15-17, rarely 15), and a more slender body (depth at dorsal-fin origin 19.2-23.5% SL vs. 23.7-25.3% SL; depth at anal-fin origin 17.5-23.5% SL vs. 23.2-26.3% SL). It further differs from congeners by the following unique combination of characters: 49-52 total vertebrae, fleshy narial flap not extending medially much past medial margin of naris, mouth rictus reaching vertical through middle of orbit, rough anterior edge of pectoral spine, 43-49 branched anal-fin rays, and caudal peduncle depth 7.8-8.6 % SL (Ref. 96851).
Body shape (shape guide): elongated.
Found in a clear, slow and moderate flowing river with a depth of 1-4 m (Ref. 96851).
