description Scalloped hammerhead Overview
The scalloped hammerhead, Sphyrna lewini, takes its name from the curved, indented front edge of its broad hammer-shaped head. This structure, called a cephalofoil, separates it visually from the straighter-headed great hammerhead. A member of the family Sphyrnidae, it occurs in tropical and warm temperate waters worldwide, using coastal habitats as well as offshore waters. Its prey includes fish and cephalopods, with crustaceans also forming part of its diet.
Large schools are a notable feature of the species, although schooling does not itself establish that each group is genetically distinct. Population structure concerns broader patterns of reproduction and movement. The IUCN classifies it as Critically Endangered, with fishing pressure and the shark fin trade major threats. It suits readers comparing hammerhead species, especially the contrast between its conspicuous schooling behavior and the more solitary habits of some relatives.
