From The Devils's Teeth : In a world where very little is known for certain, we knew that below us a great white shark was orbiting, waiting for the seal to bleed some more, and that this shark would soon be returning for breakfast. It might be Betty or Mama or The Cadillac, one of the huge females that patrolled the east side of the island. These big girls, all of them over 18 feet long, were known as The Sisterhood. Or it might be a "smaller" male (say, 14 or 15 feet) like Two Spot or T-Nose or the sneaky Cal Ripfin. These sharks were called The Rat Pack. It might be any number of great whites. At this time of the year there were scores of them cruising this 120-acre patch of sea, swimming close to the shoreline of Southeast Farallon Island as hapless seals washed out of finger gulleys at high tide and into the danger zone. In any given year more than a thousand people will be maimed by toilet bowl cleaning products or killed by cattle. Less than a dozen will be attacked by a great white shark. In this neighborhood, however, those odds do not count. At the Farallon Islands in autumn, your chance of meeting a great white face-to-face is better than even money, should you be crazy enough or unlucky enough to end up in the water.
