Elasmobranchii (hajar och rockor) (sharks and rays) >
Lamniformes (Mackerel sharks) >
Odontaspididae (Sand tiger sharks)
Etymology: Odontaspis: Etymology not explained, presumably odontos (Gr.), tooth, and aspis (Gr.), shield, perhaps referring to how teeth comprise a prominent narrow cusp provided with two or more small “side teeth” (translation), i.e., cusplets, which, with some imagination, could be said to “shield” the main cusp; another explanation: aspis (L.), viper, perhaps referring to outwardly pointing teeth of O. ferox, like that of a viper. (See ETYFish); noronhai: In honor of Adolfo César de Noronha (1873-1963), late director of the Funchal Museum (Madeira), where holotype is housed. (See ETYFish).
