Paul Spong was a zoopsychiatrist. He started his practice at the Vancouver Aquarium in Canada, taking care of a female orca: Skana. He became interested in her behavior and, year after year, Skana showed extraordinary intelligence and sociability.

I am writing to you from Hanson Island, a place far from civilization, in British Columbia (Canada) where Paul Pong and his family have lived since 1972, between Vancouver Island and the Canadian continent, surrounded by snow-covered peaks and century-old trees (there is a thousand-year-old tree!).

I needed to know the conditions of captivity in a dolphinarium. To really be able to talk about it. I had organized myself so that the team wouldn't be aware of anything, while at the same time gaining their trust.
In order to tell the real story of such an undertaking, I worked on the acoustics and sonar of the dolphins.
