We examined the morphological and kinematic basis of prey capture in the Acipenseriform fish <jats:italic>Scaphirhynchus albus<\/jats:italic>, the pallid sturgeon. Feeding pallid sturgeon were filmed in lateral and ventral views and movement of cranial elements was measured from video sequences. Sturgeon feed by creating an anterior to posterior wave of cranial expansion resulting in prey movement through the mouth. The kinematics of <jats:italic>S. albus<\/jats:italic> resemble those of other aquatic vertebrates: maximum hyoid depression follows maximum gape by an average of 15 ms and maximum opercular abduction follows maximum hyoid depression by an average of 57 ms. Neurocranial rotation was not a part of prey capture kinematics in <jats:italic>S. albus<\/jats:italic>, but was observed in another sturgeon species, <jats:italic>Acipenser medirostris<\/jats:italic>. Acipenseriformes have a novel jaw protrusion mechanism, which converts rostral rotation of the hyomandibula into ventral protrusion of the jaw joint. The relationship between jaw protrusion and jaw opening in sturgeon typically resembles that of elasmobranchs, with peak upper jaw protrusion occurring after peak gape. J.
