Nurse Sharks: The Sharks That Like to Cuddle with Sergio Madrigal Mora
Episode 103
Thursday, 26 March, 2026

Sometimes called the 'couch potatoes of the sea', nurse sharks are famous for their laid back attitude to life spending most of their days cosied up in piles, napping. But their gentle, docile nature doesn't make them any less special. In this episode, we sit down with SOSF project leader and PhD Researcher Sergio Madrigal Mora - who has spent a lot of time hanging out with the Labradors of the shark world - to discuss how nurse sharks are perfectly adapted to life in the tropics and why they form 'cuddle huddles' on the sea floor. And, we learn more about Sergio's research into the influence of changing temperatures on the movements of Pacific nurse sharks in Costa Rica's St Elena Bay.
