Well, from my recollection, the video game, Unlimited Cruise, used the unofficial animal motifs for the Straw Hats. As I believe Franky's costume was designed after a rhino, when Oda said he resembled a bull. To me, whatever Oda says about his series is what matters. So i'll always associate Zoro with sharks. Period.
