[Ichthyology • 2013] Sphyrna gilberti | Carolina Hammerhead • A New Hammerhead Shark (Carcharhiniformes, Sphyrnidae) from the western Atlantic Ocean

Carolina Hammerhead Sphyrna gilberti Quattro, Iii & Grady 2013

Sphyrna gilberti sp. nov. is described based on 54 specimens collected in the coastal waters of South Carolina, U.S.A. Morphologically, Sgilberti sp. nov. is separable from S. lewini (Griffith & Smith 1834) only in the number of precaudal vertebrae. Due to rarity of specimens and the highly migratory behavior of most sphyrnids, the range of Sgilberti sp. nov. is unknown.

Key words: Carolina hammerhead, cartilaginous fishes, Chondrichthyes, cryptic species, Elasmobranchii
