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).
