In this Thursday, March 24, 2011 photo, Trainer Lisa Mignogna and a dolphin as seen below the water level during a rehearsal of the new Georgia Aquarium attraction, AT&T Dolphin Tales, in Atlanta, Ga. It's a Broadway-style show, complete with an ancient sailor named StarSpinner and a battle with a sea creature that can only be settled by dolphins leaping, twisting and spinning the audience out of captivity. The 1.8 million gallon exhibit at the Georgia Aquarium opens April 2 after a six-month delay, largely because the first major expansion for the five-year-old downtown attraction wasn't ready yet.
