1. Bay, Kahuku, Oʻahu. Turtles commonly feed in the bay, so former area residents named it Turtle Bay. The name predates the completion of the hotel in May 1972. A ban on catching all sea turtles has been in effect in Hawaiʻi since July 1978, when the green sea turtle was placed on the list of threatened species under provisions of the Endangered Species Act. As a result of the ban, many turtles are found in the bay and elsewhere on the North Shore. 2. Beach, Mākaha, Oʻahu. West of Mauna Lahilahi. Also known as Keawaiki, Papaoneone. 3. Island, Kāneʻohe, Oʻahu. Off the north end of Mōkapu Peninsula near Pyramid Rock. The outline of the island resembles a turtle shell. Also known as Kekepa, Turtleback Island.
