Ref. principal Robins, C.R., R.M. Bailey, C.E. Bond, J.R. Brooker, E.A. Lachner, R.N. Lea and W.B. Scott, 1991
Notas Inhabits slow-flowing water of large rivers, usually in water deeper than 1.3 m. Feeds on plankton. The extended upper jaw (= paddle) may help to channel plankton into the mouth. Fish larger than 22.5 cm SL are indiscriminate tow-net filter feeders on plankton, while young paddlefish are selective plankton feeders (Ref. 46977).
