In 2008, the scalloped hammerhead was placed on the "globally endangered" list. Research has shown that in some parts of the Atlantic Ocean, populations have decreased by 95% in the last 30 years. The reason for this is because of over-fishing for shark fins. Their fins are made into shark fin soup. Researchers are calling for a ban on Shark finning, which is when the fin's of sharks are cut off and the rest of the animal is thrown back into the water to die. Hammerhead sharks are the most commonly caught sharks for finning.
