From the screenplay:
A riffly blur, color alternating with black and white. The dizziness stops on a book page showing a black and white rendering of eight species of shark. The banner at the top of the page reads: THE KNOWN AND REPUTED MANEATERS. The riffling begins again, stops on a grizzly photograph of scar tissue on six former shark victims. Riffling -- stop. Photograph of five Ichthyologists posing on wooden stools,
framed by the enormous jaws of a prehistoric shark from the family Carcharodon charcharias.
