Wow - I've seen all of these things after parasite cleansings and flushes.
Some of them I thought might be salad 'leftovers'. All of those 'tomato skin looking bits I can identify for sure, though. I wonder if it is the skin of the fluke and the soft fleshy parts above are the body.
I did get 1 3.5" fluke out intact which looks exactly like all your parts above, just the fleshy part. The tomato skin parts were separate - I guess they lose their skin maybe as a result of dying? I think he was either hanging on my liver or in a bile duct.
