Fishers living along the length of the Rewa were the first to bring the presence of young hammerheads to the attention of Kelly Brown, a marine conservationist at the University of the South Pacific in Suva, Fiji. Including the newly described Carolina hammerhead, a cryptic species difficult to distinguish from scalloped hammerheads, there are nine recognized species in the family Sphyrnidae (which includes all hammerhead species and the closely related winghead and bonnethead sharks). The main reason for this decline is the rising demand for shark fins. Topic: Scalloped Hammerhead Shark (Sphyrna lewini).

In coastal areas of the Mediterranean Sea, hammerhead sharks in general were once abundant but haven’t been seen since 1963 [pdf].
