The bottlenose dolphin calf born April 17 at the National Aquarium in Baltimore died Sunday of a suspected respiratory infection, aquarium officials said. The unnamed male calf stopped nursing early Sunday and died hours later. Results of a necropsy performed at the Johns Hopkins University are expected in two to three weeks. Brent Whitaker, the director of animal health, said about a third of newborn dolphin calves - wild or captive - die in their first year. "It's not uncommon, unfortunately," he said. "But it's not a good thing. ... We're very saddened."
The aquarium has lost two of seven calves born there.
