Humans are always looking for the life of alien planets.
One day,
A series of pictures came from Space,
Many labor think,
No air on the surface of the planet,
No water detected on the planet,
Abandoned the planet,
Think there is no life on the planet.
Actually,
They are a kind of stone life,
They don't need water,
No air is needed,
Picture of the stones captured by Space 365,
Is one of them,
Because they have swallowed some red minerals,
So there are red nails on the body.
Called by any ethnic groups red nails stone.
