Etymology: Marcusenius: Becasue of J. Marcusen, author of "Zur Phauna des Schwarzen Meeres", 1867; ichthyologist;  elegans: The species epithet is based on the Latin word elegans, meaning elegant, referring to its slender body; the name is treated as an adjective (Ref. 127382).

簡単な記述 形態学 | 形態計測学

背面の脊椎 (合計): 0; 背鰭 (合計): 26-30; 肛門の骨 0; 臀鰭: 31 - 35. Diagnosis: Marcusenius gracilis has notched teeth (Ref. 93659). A much smaller dorsal to anal fin base ratio distinguishes Marcusenius thomasi from M. gracilis, being 0.7 vs. 0.79; M. mento is characterized by a higher number of lateral line scales, more than 76 vs. less than 77 for M. gracilis; M. ussheri differs by its lower number of lateral line scales, less than 65 vs. more than 70 in M. gracilis, its smaller pectoral fin length to head ratio, which is less than 0.9, and its usually deeper caudal peduncle, the ratio caudal peduncle depth to length less than 0.3 vs. more than 0.32 in M. gracilis (Ref. 93659). Marcusenius furcidens is distinguished by a combination of its higher count of dorsal fin rays, being more than 29 vs. less than 30 in M. gracilis, a longer dorsal fin, a higher ratio of dorsal to anal fin base, being 0.78, and a greater body depth; males of M. furcidens have no distinct kink in the anal fin base, in contrast to the males of M. gracilis; relative to the P phase of its EOD, M. furcidens EODs have a stronger N phase amplitude than those of M. gracilis (Ref. 93659).

生物学     用語集 (例 epibenthic)

Found in a series of stagnant pools; some pools were quite deep and inhabitated by hippos who could dive; the river banks were high and steep, and difficult to climb when wet, revealing high water and violent current at some times in the year (Ref. 93659).
