Here is a close-up of a smaller section. Its not clear. Its white. But, to me it looks like an encasement of some sort with smaller worms inside. Ive been doing daily coffee enemas and have seen lots of these, only smaller and some are not encased. Often the worms come out stained by the coffee, only this one isnt completely stained because I had to skip yesterday. Thats my guess anyway. Im also seeing smaller ones 2-6 inches) not encased that have a floating stomach or egg sack of some sort. I can post pictures of those too if its helpful.
