The Great Hammerhead Shark (Sphyrna mokarran) is easily confused with many other sharks, including the Smooth Hammerhead, Scalloped Hammerhead, and Bonnethead Sharks.

The Great Hammerhead is the largest of all nine species of Hammerhead Shark. It's "hammer head" is believed to be a device that helps these sharks steer and turn quickly through the ocean.

It is found in Coastal-Pelagic areas all around the shores of Atlantic Ocean, Indian Ocean, and parts of the Pacific Ocean.

It is Endangered (EN).

Human InteractionEdit

The Hammerhead Shark is very capable of inflicting injuries to humans, in fact there have been many reports of divers being charged or attacked by these sharks. They are the most aggressive of the Hammerhead Sharks, although typically only attacks if provoked or if scared.

The International Shark Attack File lists 34 attacks- only one of them being fatal. Although, the Great Hammerhead Shark is hard to identify, and it's hard to know for sure which attacks are an actual Great Hammerhead.

Conservation StatusEdit

The Great Hammerhead is extremely vulnerable to overfishing and their population has dropped by 50% since the 1990s. It is an endangered animal.
