Re: What are these (pic)?

Yep, flukes... Sorry...
There are different kinds, at different stages, that's why so many variations...
I think these (in your picture)are intestinal.
Often, where there's one kind there are others.

Look at this site, the pictures are a bit different from what you'd see in the bathroom, this would be under glass, stained...

Do a cleanse as soon as possible,
you'll be fine.
