Acipenser is a genus of sturgeons.With 17 living species (others are only known from fossil remains), it is the largest genus in the order Acipenseriformes.The genus is paraphyletic, containing all sturgeons that do not belong to Huso, Scaphirhynchus, or Pseudoscaphirhynchus, with many species more closely related to the other three genera than they are to other species of Acipenser.
