Picture an animal that rests its tail in water hot enough to cook your proteins while keeping its head in a cooler current, living happily in a boiling, toxic vat of heavy metals on the deep ocean floor. Meet the Pompeii worm.
This episode dives 2,500 meters down to one of the most heat-tolerant complex animals ever discovered, unpacking the exact biological tricks that let it survive a hydrothermal vent. From bacterial armor to acidic blood to secret underground nurseries, it reveals adaptations with real promise for medicine and industry.
