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): 8; 肛門の骨 0; 臀鰭: 7 - 9; 脊つい: 39 - 44. Couesius plumbeus is distinguished by having the following characters: barbel at corner of large, barely subterminal mouth; moderately pointed snout; large eye; head flattened above and below; dorsal fin origin over or slightly behind pelvic fin origin; complete lateral line, 53-70 lateral scales; 8 anal rays, and pharyngeal teeth 2,4-4,2 (Ref. 86798). Spineless fins, normal jaws, and tiny barbel at the corner of the mouth (Ref. 27547). Body moderately compressed and slender, coloration include brown to green above, dark stripe along silver gray side, darkest on young and large male, sometimes black specks on side and belly, dusky caudal spot. Large male may have red at pectoral and pelvic fin origins, corners of mouth (Ref. 86797). In some populations, breeding males develop bright orange-red patches on sides of head and at bases of pectoral fins, but the presence of this color varies from place to place (Ref. 27547).

生物学     用語集 (例 epibenthic)

Inhabits virtually any body of water, standing or flowing, large or small (Ref. 5723, 86798). Common in gravel-bottomed pools and runs of streams and along rocky lake margins (Ref. 86798). Mostly found in shallow water, but may move to deeper parts of lakes during hot weather (Ref. 27547). Feeds on zooplankton, algae, terrestrial and aquatic insects, and small fishes (Ref. 1998).

Spawning individuals form schools that move from lakes or deeper parts of streams to shallower water (Ref. 27547). Also Ref. 10280.
