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);  lalandii: In honor of naturalist and explorer Pierre Antoine Delalande (1787-1823), who collected type [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).
