The marginfk gave me a bit of a headache, but neat specimens, OP.
I'm really interested in the identification of the 2nd to last photo - when they left me I called them "fruit roll ups". These were some of the first specimen types to leave me with treatment, and my intuition tells me they are the worst of the bunch.
But my ozone colon therapy practitioner, who calls many of my photos parasites, calls this stuff mucoid plaque. She says it is rolled up because it was lining the intestines before it broke free.
Others call this stuff liver flukes.
Regardless it is very evil. Can anybody clarify the ID?
