Ka’ahupahau’s brother, Kahi’uka, was also a guardian (via Kamahao Canoe Club). Guardian sharks, known as Pu’uloa by native Hawai’ian, are not exclusive to Pearl Harbor. Indeed, they are said to be found along the coastlines of every island in the archipelago. Ka’ahupahau and Kahi’uka protected life on land and in the sea from the evil man-eating sharks, fending them off with vicious strikes from their tails and splashing to let nearby fishermen know that danger was near. They could also take different forms: Ka’ahupahau could turn herself into an extremely tough net, while her brother could take the form of an underwater stone.

The dock that was destroyed was replaced with a floating dock that exists to this day. Engineers say that area of Pearl Harbor is subject to tremors and seismic activity that prevent anything from being attached to the bottom of the lagoon. Still, some native Hawai’ians believe that it’s not the Earth that is shaking, but rather the thumping of guardian shark tails preventing further construction to Pu’uloa.
