Etymology: Polyodon: Greek, polys = a lot of + Greek, odous = teeth (Ref. 45335);  spathula: Polyodon, many toothed, perhaps due to the numerous gill rakers because adult paddlefish lack teeth, although young fish has many small teeth, and spathula meaning spatula, due to its elongated snout (Ref. 79012).

North America: Mississippi River basin from southwestern New York to Montana and south to Louisiana; Gulf Slope drainagaes from Mobile Bay in Alabama, to Galveston Bay in Texas, USA. Formerly in Great Lakes basin, probably extirpated. At least one country reports adverse ecological impact after introduction.
北美洲: 密西西比河流域, 包括密蘇里河進入蒙大納,俄亥俄河與他們的主要支流。 至少一個國家報告引入後的不利的生態衝擊。 國際間的買賣限制。 ( 引用2, 自從 11.6.92 以後)

簡短描述 型態特徵 | 形態測量圖

Snout long, canoe-paddle-shaped; gill cover with large, fleshy, pointed flap (Ref. 86798).

生物學特性     字彙 (例如 epibenthic)

Usually inhabits water deeper than 1.2 m in slow-flowing large rivers, lakes, and impoundments (Ref. 86798). Feeds on plankton. The extended upper jaw (= paddle) may help to channel plankton into the mouth. Threatened due to over harvesting, habitat loss and pollution (Ref. 58490).

棲息於大河的緩慢流動水, 通常在深度超過 1.3 公尺的水域。 吃浮游生物。 擴大的上頜 (= 槳) 可能進入嘴巴之內對峽道浮游生物幫助。 受威脅的在捕穫, 棲息地損失與污染之上由於.(參考文獻 58490)
