What is the only animal in the world, made of metal, that lives at the vent of a hydrothermal vent?

Now the biodiversity is enough to make human beings breathtaking, but you must know that many organisms have evolved for a long time, in order to be able to survive on the earth and adapt to the earth's environment, various organisms have also evolved different abilities, such as there were many carnivores at that time, in order to be able to eat more food, so they evolved very sharp claws, and the running speed has been improving, and there are many prey in order to be able to survive, but also learned some instincts, For example, some animals will change color, some animals will disguise, and among many animals, the most effective animals to protect themselves are crustacean animals, in nature like crabs, turtles and other animals, they have evolved, very hard shells.

According to statistics, there are more than 20,000 kinds of crustaceans on the earth, these crustaceans often have no natural predators, because when predators come to eat them, they will retract into the shell, there is no way to eat, there is a creature on the earth, they have the hardest shell in the world, the shell of this creature is made of iron, this creature is called the scaly gastropod snail, many people feel that the snail is very fragile, with human strength, it is too easy to crush the snail, But the snail we introduced today, its shell is very hard.

It is understood that even the bullet can not penetrate the shell of this snail, the range of this snail life is more than 2000 meters under the sea, generally speaking, this snail lives in the fountain mouth of the deep sea, so the pressure they can withstand is also very large, it is because their shell is so stiff, to be able to withstand such a great pressure, as of now, this snail is the only one in the world that integrates metal iron into the bones, in the Cambrian era, there are few scale mollusks on the earth, At that time, the environment of the earth was very poor, but now the environment of the earth is much better than in the past.

But this kind of snail is still rare, the first time this snail was found in a sea area of the Indian Ocean 9 years ago, when a researcher discovered this snail, and the reason why this snail will evolve, such an ability is to resist other predators, and snails also have to prevent the same kind, after all, snails eat each other is also a very common phenomenon, their scales can also emit venom, and this snail heart is very strong, accounting for 4% of the entire body weight, about this process, Scientists still need a series of studies to know the secret behind this snail, like this snail has such a hard shell behind it, if this technology can be applied to the human world, is it possible to develop a lot of things?

It's the gastropod snail.

The shell of the gastropod snail is one of the hardest biological shells in the world, made of iron, a metallic substance.

It is a snail with a very hard shell that incorporates metal into its body, resulting in an incomparably hard physique.

Known as the scaly-horned gastropod snail, this snail has a metal shell that is so hard that it can withstand the tremendous pressure of the ocean floor.

Squamosaurus gastropod snail. They generally live at the vents of abyssal hydrothermal vents on the floor of the Indian Ocean.
