> Acipenseriformes (Sturgeons and paddlefishes) > Polyodontidae (Paddlefishes)
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).

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

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).
