The amphitheater at the National Aquarium in Baltimore will be closed at least until mid-week so Nani, a 21-year-old dolphin, and her new calf -- born at 5:25 p.m. yesterday -- can have some quiet, get-acquainted time.
The Atlantic bottlenose dolphin mother and calf appear to be all right, said Vicki Aversa, spokeswoman for the National Aquarium.
Nani was in labor for about an hour, considered average for a dolphin bearing its third calf.
