    • ‘Transfer the sturgeon to a cutting board and reserve any excess liquid.’
    • ‘The tail fin of most ray-finned fish, with the exception of sturgeons and paddlefish, is homocercal, nearly symmetrical about the midline.’
    • ‘Also, being closely related to sturgeons (family Acipenseridae), American paddlefish produce highly coveted roe, or caviar.’
    • ‘Either a basal gnathostome such as a shark or a basal actinopterygian such as a sturgeon would be equally instructive.’
