Sphyrnidae (Hammerhead, bonnethead, or scoophead sharks)
Etymology: Sphyrna: Probable misspelling of sphyra (Gr.), hammer, referring to their hammer-shaped heads. (See ETYFish); gilberti: In honor of ichthyologist Carter R. Gilbert (b. 1930), Florida State Museum of Natural History, who first reported (1967) an anomalous specimen of S. lewini that is likely the first recorded individual of this species. (See ETYFish).

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
This species is distinguished from its congeners by having a head length greater than 20% of STL (stretched total length); cephalofoil has median indentation; with inner narial groove; pelvic fins with straight rear margins; 91 or fewer precaudal vertebrae (Ref. 94083).
Measurements given in STL, stretch total length (Ref. 94083).
