Short description
เครื่องมือที่ใช้ในการแยกชนิดสัตว์,สิ่งมีชีวิตออกจากกัน | สัณฐานวิทยา | ความยาวต่างๆ
This species is distinguished in having smaller eyes (eyeball diameter 19-21.3% HL) and possessing fainter coloration with reduced lateral dark band as compared to its congeners; pectoral fin with 10 branched rays; weakly developed serrae in the posterior margin of the dorsal-fin spine (vs. well developed in P. laurentii); and, lacking the dorsal dark stripe along dorsal and anterior adipose fins (vs. presence in P. avanhandavae (Ref. 55501).
Collected mainly in soft-bottomed pools with very slow current, averaging 1.5 m deep, 5 m above the mainstream level. Individuals were observed calmly swimming near the bottom, in the midwater and near the surface. Elusive fishes and apparently photophobic (Ref. 55501).
