Mysterious Impregnation: Stingray's Miraculous Birth Without a Mate

A female stingray at a North Carolina aquarium is pregnant despite the absence of a male mate, prompting speculation about the cause. The aquarium is considering two possibilities: a rare form of asexual reproduction called parthenogenesis, or potential impregnation by a male shark. An ultrasound revealed that the swelling in the stingray's body was actually eggs, and bite marks on the stingray suggested mating behavior. The aquarium is awaiting the birth of the pups to confirm the cause of the pregnancy.
