"Pregnant Stingray Charlotte Defies Odds in Male-Free Aquarium"

Charlotte, a stingray living in a mountain aquarium in North Carolina, is pregnant despite not having a male companion for at least eight years. The aquarium's owner believes she could give birth to as many as four pups through parthenogenesis, a type of asexual reproduction. This rare phenomenon has surprised experts, as it is the only documented example for this species. The nonprofit running the aquarium is preparing for the arrival of the pups by seeking a larger tank and live cameras for public viewing.
