Etymology
the word is a transparent modern english compound, formed by combining the common noun 'paddle', referring to its broad, oar-like shape, with 'fish'. the term is descriptive, coined in american english in the late 18th century to name the distinct species characterized by its elongated rostrum. the logic is purely morphological, comparing the fish's prominent snout to the blade of a paddle used for propelling a boat through water. no deeper classical etymology is involved, as it is a straightforward vernacular name based on observable anatomy.
