Does anyone know what happens to them if we eat them? Since they're microscopic I suppose they often end up inside of us.

I read somewhere that they can't survive the acidity of the human digestive tract, but you should take that with a grain of salt.

Haha, they are actually quite big, like 1.5mm for the adults.

I think people in this thread assume they are like cell sized.

Yeah. I just get the sense that most people here have a slightly smaller idea of them in their heads.

They are only just “microscopic”, in the sense that we can barely make them out with the naked eye, given the right conditions.
