What family contains the hammerhead sharks? Hammerhead sharks belong to the family Sphyrnidae.

Sphyrnidae is a small family within the order Carcharhiniformes, the group that includes many familiar ground sharks. Most hammerhead species are classified in the genus Sphyrna, while the winghead shark is placed in the separate genus Eusphyra.

The family name is linked to Sphyrna, a genus name derived from Greek terminology associated with a hammer. Members of Sphyrnidae share the distinctive laterally expanded head, although the outline differs substantially among species. Their relatives include requiem sharks in the family Carcharhinidae, but hammerheads are not members of that family.

Another frequent mistake is treating “hammerhead shark” as a single species. It is a group containing several species, including the great hammerhead, scalloped hammerhead, smooth hammerhead, and bonnethead. The family-level name Sphyrnidae therefore describes their broader biological classification, not one individual animal.
