APPLE VALLEY (AP) -- The first baby dolphin at the Minnesota Zoo in five years is expected to be born next summer, zoo officials said.
Ultrasound tests conducted Monday on Rio confirmed she was pregnant. For now, she will continue to follow her normal routine and perform in the zoo's twice-daily dolphin shows, officials said.
Besides adding to the zoo's four-dolphin collection, the calf would make Semo, at age 37, the oldest known male dolphin to reproduce. Previously, the oldest known male dolphin to reproduce was 32.
Although miscarriages and stillborn calves are relatively common, Rio has age and experience, two factors that should help her offspring survive, said Diane Fusco, who is in charge of the zoo's marine mammal program.
