To me this looks like a long strand of clotted blood. It does look like it may have segments so it is possible that it has been stained by the black walnut but the Tapeworms I've seen are white or lighter than this.
Google "Dissected Ascaris" or look at the link below. To me, it looks like the innards of a roundworm, but stained from bile or feces. Not positive, though.
Wow!!!!!!!!!!!! It DOES look like a disected ascaris... Maybe you can indetify the other pic I have? I will post them right now. I have always thought I had ascaris. When I was about 24 I did a nasal rinse and I SWEAR ON ANYTHING that what came out was a piece of an Ascaris worm. Dont know HOW it got attached there but it did..
So I have come to the conclusion that I have/had Ascaris.
Time to order my EXTRA STRENGTH HUMAWORM.
REMEMBER: You have to CALL to order the xtra strength. BEST. ANTI-PARASETIC. OUT. THERE.
WHHAAAAAAAAAAAAATTT!????? CLOTTED BLOOD?!?!?!? On day 10ish on Humaworm there was a time where I was on the ground literally crying for help. My poor partner looked terrified seeing me like this... it felt like something was punching me in the stomach. I had diarrhea for almost 24 straight hours. It wasn't until a couple of days later "this" comes out.
This was just one pic of the "things" that came out of me during my Humaworm flush.
Keep in mind I was taking fiber, carnivora, ANNNDDD humaworm.
My opinion is that is a dead roundorm. I got one just like that a couple of weeks ago. Sometimes roundworm come out deflated and stringy, other times they come out bloated. I was taking psyllium when I got mine, and some would say it was the psyllium, but you could definately see the worm throughout the entire length of the creature. Maybe the psyllium bloats the worms like it bloats us when they ingest it.
The color is very dark, but probably just because you are getting into old junk.
I didn't post the picture of mine at the time, but here it is in case it helps you.....
