This photo from the Audubon Nature Institute shows stranding coordinator Suzanne Smith watching a 2 ½-year-old male dolphin on Sept. 6, 2012, at the Audubon Aquatic Center in New Orleans, where the dolphin spent six months in rehabilitation. He was found on March 6, 2012, stranded and blistered from sunburn, on a mud flat off Grand Isle. Because a hearing test found that he was deaf and could not survive in the wild, he will be taken on Tuesday, Sept. 11, to the Institute for Marine Mammal Studies in Gulfport, Miss.
