The Snail With Iron Armour the Military Couldn't Replicate (Scaly-Foot Snail) This snail built better body armour than we did. The scaly-foot snail lives at 2,400 meters deep, around hydrothermal vents that dissolve iron from the seafloor. It absorbs that iron directly — depositing it into thousands of interlocking scales covering its foot. Three-layer armour. The outer absorbs impact. The middle disperses energy. The inner holds structure. The US military studied it. Engineers modelled it. Still cannot replicate it. It didn't survive its environment. It consumed it — and wore it.
