There's a new dolphin calf at the National Aquarium in Baltimore.
An Atlantic bottlenose dolphin named Jade gave birth to the calf Wednesday night. The newborn dolphin was about 30 pounds and 2 to 3 feet long at birth.
Aquarium staff haven't been able to determine the sex of the calf yet. But they say the calf appears to be healthy. It has started to nurse and has been swimming alongside Jade and another female dolphin.
The aquarium notes that even with a successful birth and an experienced mother, about one-third of dolphin calves don't survive their first year of life -- either in the wild or in captivity.
Jade's first calf survived and is now three years old. The birth brings the aquarium's dolphin population to 11.
All dolphin shows have been temporarily suspended.
