THE DEVILS TEETH is an exceptionally well-written account of the Farallon Islands and, in particular, the white shark research project that has been based there over the past several decades. Susan Casey profiles Peter Pyle and Scot Anderson, two biologists who have been leading shark research at the islands which are located just 27 miles due west of San Francisco. She also documents her own (ultimately disastrous) experiences gaining access to the islands which are largely prohibited to the public. The stars of the story are the sharks themselves, who turn out to be far more individualistic and personable than you would probably ever imagine.
The white sharks of the Farallon Islands are perhaps the best studied in the world in their natural state. The circus atmosphere which surrounds white shark research in places like Australia and South Africa have largely compromised the sharks natural habitat making it difficult to observe sharks behaving naturally. The Farallon Islands, known to 19th-century mariners as "The Devil's Teeth," are a dangerous and foreboding locale, but one that lends itself well to scientific investigations. Casey takes us through the history of exploitation, inhabitation, and research that has taken place on the islands over the past 150 years, and she includes a healthy amount of information about the other wildlife in evidence on and around the islands. But she clearly (and admittedly) developed an obsession with the sharks, and the narrative of the book is continually steered back toward them.
The thing that struck me the most in THE DEVIL'S TEETH was the description of the individual white sharks' strong personalities. I would never have thought that a white shark could be described in terms of being "gentle and maternal" (Whiteslash) or "happy-go-lucky and somewhat goofy" (Half Fin). Other individual sharks, of course, had more sinister reputations. Still, one can come away from reading this book with the impression that the great white shark is truly a likeable animal, if not exactly huggable. Another revelation (to me, at least) was the evidence that at least some white sharks, like whales, apparently have fixed migratory routes that can take them thousands of miles through the course of a year. Some (the females) appear to have two-year migrations since they only show up every other year in the Farallones.
Susan Casey takes us into an exclusive place, to be sure: a world where cage divers and eco-tourists are looked down upon with disdain. In a way, it hardly seems fair that the experience of witnessing the thrill of a white shark kill should be so restricted. As Peter Pyle himself said, "I feel sorry for anyone who hasn't seen one." Of course, it is understandable. As in nearly other place in the world where white sharks congregate, the delicate ecosystem of the Farallon Islands would suffer tragically and research effort would be compromised from increased human intrusion. THE DEVIL'S TEETH is a glimpse into the world of two committed biologists and the truly majestic animals they study.
