Although they have been said to be dangerous towards humans, Great Hammerhead Sharks rarely ever attack humans. Divers have reported that Great Hammerhead Sharks are shy and avoid humans, but there have been reports of Great Hammerhead Sharks approaching divers closely and even chasing them. In 2009, the International Shark Attack File listed 34 attacks caused by a shark which belonged in the "Sphyrna" genus, but it is not confirmed if the shark was a Great Hammerhead Shark or not. The Great Hammerhead Shark has been confirmed to be responsible for one provoked attack.
