Don't get the wrong idea: The look on that dolphin's mug and the anguish on the face of Ximena Isabel Torres, 15 months, doesn't mean the fish is a people-eater. Ximena is merely being lowered into the Aragon Aquarium in Mexico City as part of an experimental dolphin therapy program to treat neurological disorders among children. Ximena has psychosomatic problems. Nine other children are participating in the program.
