Elasmobranchii (hajar och rockor) (sharks and rays) > Carcharhiniformes (Ground sharks) > Carcharhinidae (Requiem sharks)
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).

Inhabits shallow coastal waters, on sandy and muddy bottoms, and not normally found in lagoons and estuaries (Ref. 244). Feeds on small bony fishes, including sardines and anchovies, also shrimp and squid (Ref. 244). Viviparous, with 1 to 4 young in a litter; size at birth 33 to 34 cm (Ref. 244). Its flesh is highly appreciated and is marketed dried salted.
