The Deep-Sea Snail with an Iron Shell

The scaly-foot snail, found in extreme environments near hydrothermal vents, has a unique iron armor made of iron sulfide compounds like pyrite and greigite. This armor provides protection against predators. The snail's ability to incorporate iron into its exoskeleton is unique among animals. It is found in three locations in the Indian Ocean, with its armor formation linked to the iron-rich waters. Conservation efforts are crucial as these snails are endangered due to mineral mining activities.
