The mystery of Charlotte, the pregnant stingray with Dr David Shiffman

In February 2024, a round stingray from a small, rural aquarium in the middle of a shopping mall unexpectedly took the world by storm. She was pregnant, but how this had happened was a complete mystery - there were no male stingrays in the tank, nor had there ever been...

In this episode we are joined by scientist and science communicator Dr David Shiffman (@whysharksmatter) to examine Charlotte's case. We go deep into the various theories that could explain Charlotte's pregnancy to get to the bottom of what really happened. No, a shark did not get a ray pregnant, but what did happen is even more fascinating. It's a good excuse to take a deep dive into the more unusual methods of shark and ray reproduction, including the super cool zoological phenomenon that is parthenogenesis!
