The world is waiting for a stingray to give birth in the small town of Hendersonville, N.C. That's because it's not clear how she got pregrant, as there's no other stingray in the aquarium.

A big announcement came out of a small aquarium nestled in the Appalachian mountain city of Hendersonville, N.C., on Feb. 8.

"We found out that Charlotte is expecting," Ramer said on the social media livestream."It's a really unique and strange phenomenon to happen. We don't have a male ray." What most likely happened is that Charlotte impregnated herself through an asexual reproduction process, Chapman says. In parthenogenesis, when a female produces eggs, an egg byproduct with nearly the same DNA fuses back with the eggs instead of a male fertilizing them.There's another conception theory. There were two male white-spotted bamboo sharks in Charlotte's tank, according to Ramer. She says they started seeing bite marks on Charlotte, possibly indicating a shark mating behavior.

"Parthenogenesis has a tendency to produce offspring that are not very healthy," Booth says."In all of the studies in snakes, birds, sharks, the offspring don't survive very long. They're stillborn or they expire within a short amount of time."
