Acipenseroidei is a suborder of acipenseriform ray-finned fish. It contains the sturgeons (Acipenseridae) and paddlefishes (Polyodontidae), both living and fossil species.^[1]

Sturgeons are well known for the production of caviar.

In 2020, an American paddlefish (Polyodon spathula) was hybridised with a Russian sturgeon (Acipenser gueldenstaedtii), producing what the Hungarian scientists responsible named a "sturddlefish".^[2]^[3]
