Tucked along the volcanic shores of the Galápagos lives a creature that defies expectations. It is a reptile that dives into the cold ocean, feeds underwater, and sneezes out salt like it’s no big deal. In this episode of Saltwater Stories, we follow the marine iguana, a species so strange it once puzzled Darwin and now fascinates scientists around the world. From its prehistoric look to its ability to shrink its skeleton during hard times, this lizard is a master of extremes. Join us as we uncover how it survives, what threatens its future, and why its story matters far beyond the islands it calls home.
