Scientists have confirmed the second-ever case of a “virgin birth” in a shark, indicating once again that female sharks can reproduce without mating and raising the possibility that many female sharks have this incredible capacity.
Scientists have proven through DNA testing that the offspring of a female blacktip shark named “Tidbit” contained no genetic material from a father. Tidbit had lived at the Virginia Aquarium in the Norfolk Canyon Aquarium for eight years since shortly after her birth in the wild.
Scientists did not even know that Tidbit was pregnant until after she unfortunately died and a necropsy was performed. “Sadness turned to surprise during the necropsy when we found that she was pregnant,” Beth Firchau, Curator of Fishes, said. “There were no male blacktips in the tank for the past eight years!”
