Dr. Norris tells us how the dolphins swim, find food, breathe in rough weather, and how they protect themselves in an underwater world totally without places to hide. Norris shows us how his scientific ideas evolve, takes us on a hair-raising trip aboard a tuna vessel where he and his colleagues dive in the net to search for solutions to the kill, and finally suggests how the “magic envelope,” the dolphins’ group protection system, might be the key to releasing them unharmed.
