Etymology: Rhizoprionodon: rhiza (Gr.), root; prion (Gr.) saw; odon (Gr.), tooth, referring to teeth with serrated (saw-like) bases, or roots [replacement name for Rhizoprion Ogilby 1915, preoccupied by Rhizoprion Jourdan 1861 in mammals]. (See ETYFish);  longurio: Latin for a tall person, or a “slender youth or stripling” per Jordan & Evermann (1896), allusion not explained, perhaps referring to small, slim body of holotype (a male, presumably mature at 76.2 cm long), much smaller than its presumed congeners in Carcharias (original genus). (See ETYFish).
