With rocks and strong currents, the area is dangerous to ships, but no shipwrecks occurred when Jack was present. Many sailors and travellers saw Pelorus Jack, and he was mentioned in local newspapers and depicted in postcards. Jack was last seen in April 1912. There were various rumours connected to his disappearance, including fears that foreign whalers might have harpooned him. However, research suggests that Pelorus Jack was an old animal; his head was white and his body pale, both indications of age, so it is likely that he died of natural causes. Since 1989, Pelorus Jack has been used as a symbol for the Interislander, a ferry service across the Cook Strait, and is incorporated into the livery of the ships in the fleet. Shooting incident In 1904, someone aboard the SS Penguin tried to shoot Pelorus Jack with a rifle. Despite the attempt on his life, Pelorus Jack continued to help ships. According to folklore, however, he no longer helped the Penguin, which shipwrecked in Cook Strait in 1909. Protection Following the shooting incident, a law was proposed to protect Pelorus Jack. He became protected by Order in Council under the Sea Fisheries Act on 26 September 1904. Pelorus Jack remained protected by that law until his disappearance in 1912. It is believed that he was the first individual sea creature protected by law in any country. Cultural references In 1945, when Bob Lowry founded his new press, Pelorus Press, in Auckland, his printer's device was a dolphin, referencing 16th century Venetian printer Aldus Manutius, and he named the press after Pelorus Jack. "It was a happy thought to maintain the old dolphin tradition. What more inevitable then ... than Pelorus Jack of the Sounds?" Kipa Hemi Whiro, a kaumātua of Ngāti Kuia is reported in 1913 as being "very positive in his belief" that Pelorus Jack was "the self-same fish of ancient days", Kaikai-a-waro, a sea-god or taniwha who had guided his ancestor Matua-hautere across Cook Strait from the North Island to settle in the South Island many generations earlier. "Pelorus Jack" is a Scottish country dance, named in honour of the dolphin. This dance features a set of alternating tandem half-reels (or heys) where two people act as one but swap who leads at the reel ends. It is also known as a Dolphin Reel. Arthur Ransome mentions Pelorus Jack as accompanying ships and receiving protection
