This episode of Radiolab, the final installment of "Week of Sharks," delves into the fascinating world of shark reproduction. The hosts, along with lead reporter Rachael Cusick, explore the three categories of shark birth: Viviparous (live birth with a placenta), Ovo-viviparous (eggs hatch inside the mother), and Oviparous (egg-laying). The story then shifts to Greg Noll, founder of Shark Club Malta, and his work rescuing and hatching shark eggs from dead sharks found at a fish market. Despite initial failures, Greg successfully hatches numerous sharks and releases them into the wild, though a conservation biologist questions the effectiveness of focusing on baby sharks rather than adult sharks. The episode concludes by highlighting how Greg's work has inspired others, including a classroom in Spain that raises baby sharks, fostering appreciation and dispelling fears about these creatures.
