A beluga whale just gave birth to a rare calf at the Georgia Aquarium!

It's rare for beluga calfs to be born in captivity, but Maris the beluga gave birth to a super tiny calf on May 10th in the aquarium.

The newborn beluga weighed 59-pounds. In the wild beluga calves usually weigh about 176-pounds, reported TODAY. 

The experts at the Georgia Aquarium shut down the beluga exhibit to give the new beluga family privacy and will watch over the mammals for their safety.
