“I found this in my loo”, writes this reader about the long, dark worm pictured below in a toilet bowl. “Please help.” He provides no further context, and we must say that the photo he provided is quite dark and not the best quality, which makes it harder to see the worm’s physical characteristics (other than the obvious ones). With that said, we can still make an educated guess as to what it is, and in any case, we would guess that it is some kind of detritivore. Detritivores are organisms that feed on decomposing organic matter, and there are plenty of worms and worm-like organisms that fit this description, including earthworms and millipedes.

“What is this worm found in a stock tank in Oklahoma?” asks this reader about the white worms with brown stripes pictured below. The worms vary in size, with some smaller worms latching on to the bigger ones.

“What on Earth are these worms?” asks this reader, who found a batch of pinkish, dead worm-like creatures beside her kitchen sink. She has since cleaned the worms up and bleached her entire counter and sink.
