What happens after a ship sinks? 🚢 Nautilus Live dived deep below the surface of the South Pacific Ocean to study shipwrecks. Microbes are the first to settle, creating a biological foundation for an entire underwater ecosystem. Over time, coral, barnacles, and fish move in, turning steel and wood into vital marine habitat. These wrecks provide shelter, food, and space for biodiversity to thrive. They’re not just relics of the past, they’re time capsules where ocean science and history collide.
