In Hawaiian culture, sharks are considered to be gods of the seas, they are also known as "aumakua", protectors of humans, and cleaners of ocean life. Some of these sharks are believed to be family members who have died and have turned into sharks. But there are some sharks which are known as "niuhi", or man-eaters. These sharks include Great White Sharks, Tiger sharks, and Bull sharks. The Hammerhead sharks are known as "mano kihikihi", they are not considered as man-eaters or "niuhi", but are considered one of the most respected sharks in the oceans, an "aumakua". Many Hawaiians believe that they have an "aumakua" which watches over them and protects them from the "niuhi".
