Merkmale
Die Scaphirhynchus-Arten haben einen spindelfΓΆrmigen KΓΆrper mit relativ breitem VorderkΓΆrper, der fΓΌnf Reihen von Knochenschuppen wie bei den anderen StΓΆrartigen aufweist. Die Schnauze ist breit und spatelfΓΆrmig. Von den Arten der Gattung Pseudoscaphirhynchus unterscheiden sie sich durch die vierlappige Unterlippe, die gefransten Barteln und den verlΓ€ngerten Schwanzstiel, der vollstΓ€ndig von Knochenplatten bedeckt ist.
Systematik
Die Gattung umfasst drei Arten innerhalb der Familie der StΓΆre (Acipenseridae).
β’ WeiΓer SchaufelstΓΆr (Scaphirhynchus albus)
β’ SchaufelstΓΆr (Scaphirhynchus platorynchus)
β’ Alabama-SchaufelstΓΆr (Scaphirhynchus suttkusi)
