Pelorus Jack was a Risso's dolphin that helped guide ships through Pelorus Sound to French Pass in the Marlborough Sounds in the late 19th and early 20th century.
Risso's dolphins are extremely rare in New Zealand, yet Pelorus Jack stuck to his routine of greeting ships in the Sound for nearly 25 years.
Author Susan Brocker's new book Pelorus Jack, the Dolphin Guide aims to introduce the extraordinary tale to a new generation of Kiwis.
Susan has more than 50 books to her name, and often combines her love of animals with her interest in historical events.
