Pittsburgh Zoo & PPG Aquarium has unveiled an elephant calf born about a month prematurely.

The calf was born at the zoo's International Conservation Center in Somerset County in May. It was unveiled Tuesday.

The female calf was born to Seeni, a 21-year-old elephant that's among three the zoo rescued from Botswana in 2011.

Zoo president Barbara Baker says officials are waiting to see how the calf adjusts and is accepted by the rest of the zoo's herd before naming it. Baker says zoo officials don't want to "jinx it."

The calf weighed 184 pounds (84 kilograms) at birth. A full-term calf typically weighs between 94 kilograms and 127 kilograms.

Normal gestation for an elephant is about 22 months.

The Tribune-Review posted Facebook video of the calf Tuesday.
