About The Species
Scalloped hammerhead sharks are moderately large sharks with a global distribution. The most distinguishing characteristic of this shark is it's "hammer-shaped" head. They are threatened by commercial fishing, mainly for the shark fin trade. Two distinct population segments of the scalloped hammerhead shark are listed as endangered and two are listed as threatened under the Endangered Species Act.
NOAA Fisheries is committed to conserving and protecting scalloped hammerhead sharks. Our scientists and partners use a variety of innovative techniques to study and protect this species.
