That's what I was thinking. The worm's fragile antennae is not even damaged. Seeing that the OP is new and never posted here before and that this worm was from "someone else" also made me further suspicious.

!!!!!
I had read some old school stuff about these type of parasites, but here's a site with a guy who's done some homework and seems to have a problem with them.

"In 2004 Ertek et al. recovered the millipede Nopoiulus kochii from the intestine of a 14-year-old Turkish boy with a history of stomach aches and burning-throat sensations; he had found active millipedes in his mouth and feces (Ertek et al., 2004). Historically cases of pseudoparasitism have been initially regarded as delusions or misperceptions, often believed to have been fabricated. However, Chamberlin in 1923 stated,

“the number of carefully authenticated cases is now so large that there is no room whatever for doubt that myriapods may live for considerable periods, in some cases months, if not years, both in the aerial passages and in the alimentary tract, through the entire length of which they may pass unharmed” (Chamberlin, 1923).

Hi,
I'm new to this forum and have recently been unfortunately introduced to the strange world of parasites. After getting my child a puppy we got roundworms from it. To my surprise while clearing up the roundworm I noticed I had many other parasitic life forms. Flukes, worms and many other goodies... I had probably had them for years. So here I am signing in after lurking on this forum for months! Thanks to all of you for sharing your experiences and knowledge. It has been helpful to not feel so alone on this journey.

So, today I'm researching a small black worm that I expelled but I believe it was killed only after taking Thyme essential oil. When I take the Oregano and Clove essential oil (in veggie capsule I make myself) I have not seen these. They look hideous but I digress....

I'll post a lovely worm photo soon.
