"Pregnant Stingray Gives Birth at NC Aquarium, Impregnated by Shark?"

Charlotte, a stingray at a North Carolina aquarium, is about to give birth despite not being around any male stingrays. The possible explanations for her pregnancy include mating with sharks or a rare process called parthenogenesis, where eggs develop without fertilization. The aquarium is expecting the birth of potentially four pups, which will provide an opportunity for DNA testing to determine their origin.
