National Aquarium’s dolphin sanctuary plan: Wave of the future or well-intentioned folly?

At 8:30 a.m. each day, before the doors of Baltimore’s National Aquarium open to the public, its resident bottlenose dolphins begin the first of their six daily training and feeding sessions, structured much like a school day for human children. Lessons are taught, knowledge is tested, and rewards given by the humans who represent the center of their universe.
