Sphyrna
''Sphyrna'' is a genus of hammerhead sharks with a cosmopolitan distribution in the world's oceans. Members of ''Sphyrna'' have a tendency to inhabit coastal waters along the intertidal zone rather than the open ocean, as their prey such as invertebrates, fish, rays, small crustaceans, and other benthic organisms hide in the sands and sediment along these zones. Members of ''Sphyrna'' are also known by synonyms such as ''Zygaena'', ''Cestracion'', and ''Sphyrichthys''. The earliest species described of this genus was '' Sphyrna zygaena'' by Carl Linnaeus in 1758, while the latest described member, '' Sphyrna alleni'', was described in 2024. The genus name comes from the Greek word ''sphyra'' "hammer", it is also where the family name Sphyrnidae comes from.
