"Unraveling the Mystery of the Shark-Impregnated Stingray"

An aquarium in North Carolina is investigating the mysterious pregnancy of its female stingray, Charlotte, as there were no male stingrays in the tank with her. The pregnancy is considered a rare science mystery and could be due to parthenogenesis or mating with young sharks. The aquarium's executive director mentioned the possibility of having partho babies or a potential mixed breed, and DNA testing will be conducted once Charlotte gives birth to her expected three to four pups.
