Animals

Here is a unique creature in the world – snail Crysomallon squamiferum, which is the only living organism that uses the “iron armor”. Foot snail is covered with a thin plates, which consist of sulphides of iron. These snails live in the Indian ocean at a depth of about 2.5 km in close proximity to hydrothermal vents and found them in 2001. Iron is also part of snail shells and a special protective layer that covers the tentacles and unprotected leg. Thanks to this feature clams can live in places with very high temperatures, where the lives of many other living organisms remains impossible.
