"Pregnant Stingray's Asexual Reproduction Mystery Solved by Scientists"

Charlotte the stingray, living alone in a tank at an aquarium in North Carolina, is pregnant despite not sharing a tank with a male for at least eight years. Experts believe she went through parthenogenesis, a rare form of asexual reproduction. This phenomenon is extremely rare in nature, but has been observed in other species. The pregnancy has garnered global interest, and Charlotte is expected to give birth to up to four pups. In a separate study, National Geographic explorers have tagged monstrous stingrays in the wild, revealing new insights into the critically endangered species.
