“Tonight I went to use the bathroom to urinate but when I looked down I noticed a living worm there”, writes Alberto in his submission regarding the dark, long, worm-like creature pictured below. “My first thought was that the worm came from me, and that it was a parasite (I did use the bathroom in the morning, but I didn’t use the bathroom until the night when I saw the worm), but when I started researching in Google it didn’t seem like the worm looked like the typical parasite that infects humans. Those seem to be white or cream, while this worm looks black with a bit of red and some transparent parts when it stretches. Also I didn’t have any symptoms the days before, like itching, however I did have some light digestive looseness the day before, but I think I’m pretty sure it was something I ate the same day, but I’m not sure though. I did take a dewormer just in case, but I would like to be sure if that worm could be a parasite that came from me. I’d leave a video and some other pics of the worm, thank you very much! I live in Monterrey, Mexico.”

“I found this worm wriggling in my clean toilet bowl”, states this reader about the darkly-colored organism pictured below. “It is about 6-inches long, brown, with thin rounded ends, but appears to have a flat body. What is it, please?” The photo she provides does not lend us much detail: when zooming in, the organism becomes merely blurry, which speaks to the low resolution of the photo. That always makes it harder to identify an organism, as its physical characteristics are the number one giveaway for its species. That said, based on the description our reader gave us, we would conclude that this is some type of flatworm.

A long, black worm-like organism was found in the toilet after this reader flushed it. Our reader, who is based in Chennai, India, asks us what this “worm or creature” is.
