Acipenser Linnaeus 1758 Latin for sturgeon, with at least three published explanations of its derivation: (1) derived from the Greek akkipesios (ἀκκιπήσιος) and perhaps equivalent to the Egyptian xipen-pennu; (2) combination of the Greek akís (ἀκίς), point, and pénte (πέντε), five, presumably referring to five rows of sharp scutes on body; (3) from the Latin acus, needle, and pensum, weight (a quantity of wool given to handmaids to be woven or spun daily), i.e., a fish that “possesses a weight of needles,” referring to the “needle-shaped barbels” that hang down from its mouth
