A Multispecies journey of the Great White Shark and caged humans.

A multimodal project.

1,600 km from Antarctica, an aluminium cage is dropped into the ocean. Suited divers climb inside and bear the frigid waters in wait of an animal which travels the lines between myth and reality. This wait can be for a minute, and for some what can seem a lifetime. For this experience, they have flown from all over the world, then travelled to the end of New Zealand and got on a boat across the turbulent Foveaux Strait. But if they’re lucky, they come face to face with an entity who can trace its lineage for at least 400 million years, an apex predator of its environment—the Great White Shark. Who are these people that come thousands of kilometers to spend a few minutes in the water with these alleged ‘monsters’? Why are they here? Do they finally find the ‘monster’? Or does something else entirely stare back at them through the bars of the cold cage? In this book, an Indian marine anthropologist anthropologist recalls his fieldwork with his British soul friend, as they undertook the journey at the intersection of two sentient species, humans and the White Sharks.

“When human beings jump in the marine environment, they know they are not at the top of the food chain. This knowledge, along with the darkness and murkiness of the environment, create the scope for conjuring up monsters who are waiting to pounce on us just beyond the realm of our vision.”


White Sharks are not monsters, nor are humans, but both offer much to fear, and admire. Two very different beings who overlap rarely and when they do it often is in a form of a conflictual, mutually preferentially avoided context. However, there is one space wherein humans and these great fish do come face-to-face in a different setting. It is in the Shark’s home space, mediated through a very particular human-controlled environment: cage diving. The opening quote frames this experience in a manner I am sure every reader can identify with, even if only in one’s imagination. But in the pages of this book, we come close to sensing that the Sharks might also be suspecting something similar about the whole endeavor. This context alone, as revealed via the sections of text focused on before, during and after the cage diving encounters and activities, makes Iridescent Skin worth reading. But the cage diving interface is actually only a small part of the adventure....

Soosie Lucas
Anthropologist & artist

Ms Soosie Lucas is a profoundly talented artist and anthropologist, and also the sponsor of this expedition, and my research assistant, quite simply this project wont exist in any form without her.  She supported with boarding and food during my work and helped copy check the thesis. She was right next to me, with months of digging through archival materials in libraries and museums, and even during interviews. Furthermore, many times, during my field work, she came out on the daily cage diving trips, and regularly bring me food and other essential commodities. When the situation arose to pitch the idea of my participant observation among the cage divers, Soosan contacted Mike (The owner and operator of Shark Experience NZ, the last surviving cage diving operation in NZ), drove us to Bluff again from Christchurch, and after a lot of discussion, was finally able to convince Mike and Carwyn (his partner), to allow me to be on their boat as a participant observer and a boat hand. More than anything else, it is an honor to call this brave and brilliant woman my closest friend on planet earth. 


The book and the thesis it was based on would have been non-existent without Mike Haines and the team of Shark Experience Bluff, New Zealand. They believed in me and helped me to accomplish the work I have done for months on their facilities. I want to then express my deepest thanks to my current primary supervisor Michael Grimshaw, who came in at a crucial time of the thesis and literally salvaged it from sure failure. I have to thank Lyndon Fraser, who was a constant support, and positive energy in my life and the project. With that I thank the University of Canterbury, and the Department of Sociology and Anthropology and all its faculty, who were always allowing me to go the way I wanted to in fully exploring this thesis. I also want to thank Dr. Piers Locke of the Anthropology programme who introduced me to multispecies ethnography and guided me a long path of the way. I thank Associate Professor Steve Crawford at the Department of Integrative Biology at the University of Guelph in Guelph, Ontario, Canada.

I want to thank the UC Alumni Association for a special fund I was awarded, again without whom I literally would not have been able to finish this thesis, and I vow to pay it forward, and help and guide future scholars of the university. I have to thank Professor Jon Harding, who has always been extremely kind to me, yet again who’s help was pivotal in the final completion of this project. And to say thanks to Soosan, my research assistant and one of my closest friends in the world for her help in this project is a gross understatement, because none of this would have existed without her.
