Does a stingray actually fire its barb & lose it, or is it like a wasp stinger?

I've read different things, and having just watched a CNN video re: the 81 yr old man who was pierced in the chest, a person talked about how the ray "fired its barb" and how "they're not sharpshooters".

Is it possible that every rock, mineral, atom - i.e every single molecule is a living being ??

May be we think of them as non-living only becuase they do not comply to our self made defination of living?? If so, than we are so ridiculously trying to search for ET beings. They are all around us.
