A precarious population of great white sharks and the ongoing scientific research intended to secure their survival is the subject of Island of the Great White Shark, a just completed documentary film by RTSea Productions. The production is the culmination of a three-year effort by filmmaker Richard Theiss to provide the first comprehensive look at the great white sharks found at the remote Mexican island of Isla Guadalupe, Baja. The film explores many of the issues surrounding these highly misunderstood animals, the efforts of dedicated shark researchers to study and protect them, and the unique cooperative relationship that exists between the researchers and eco-tourism operations.

“These are absolutely magnificent creatures living on a razor’s edge of possible extinction. And there are some very dedicated people working tirelessly to prevent that. This is a story that needed to be told,” says Richard Theiss, RTSea Productions, executive producer and cinematographer.

Theiss came to see Isla Guadalupe’s great white sharks three years ago as a passenger aboard a shark diving expedition to make the 210-mile journey south to Isla Guadalupe. What started out as an exciting adventure turned into a passion to document the work of Mauricio Hoyos Padilla, a young Mexican shark researcher, working under the supervision of leading shark experts in the United States and Mexico. This project is aided by the support of eco-tourism operators that frequent the island in the fall months, when migrating great white sharks arrive to feed on seals and tuna that inhabit the island’s waters.

Island of the Great White Shark, featuring dramatic underwater close-ups of great white sharks and exclusive footage of various research techniques, paints a portrait of the great white shark as a vital but cautious ocean predator in contrast to its more public image as a malevolent man-eater. The film also illustrates the destructive and inhumane practices imposed upon sharks by the commercial shark fishing industry. Estimates run from 40 million to as high as 100 million sharks being killed each year either for their fins or as accidental by-catch.
