our "instant index" begins with a heart-pounding encounter. Look at the photos. A school of sharks, a dive tour operator off the coast of south africa. He lowered a bucket of sardines into the shark-infested waters, and watch. First, one shark, then quickly a feeding frenzy. Dozens of others, as big as 16 feet long and 2,000 pounds.

Five good samaritans on the far side of the vehicle struggle to free her.
