A dark spot isn't necessarily just dirt.
And a damp corner suddenly seems capable of hiding all kinds of surprises.
I Couldn't Stop Looking at It
Despite feeling uneasy, I was curious.
The object still hadn't made any dramatic movement.
It wasn't racing across the floor or jumping toward me. In fact, if I had glanced at it for only a second, I probably still would have assumed it was some kind of debris.
But I had already spent too long looking at it.
Something about the texture continued to bother me.
So I slowly moved closer again.
Not close enough to touch it, obviously.
I just wanted a better look.
I focused on its shape.
It appeared somewhat elongated but contracted, almost as though its body could stretch farther than its current size suggested. Its edges weren't perfectly fixed. The surface had the sort of uneven appearance that made it seem biological rather than manufactured.
Then I noticed it.
Movement.
It was incredibly subtle.
There was no dramatic wriggling. No sudden burst of motion.
Just a slight change in position.
But that was enough.
I froze.
For a moment, I wondered whether I had imagined it.
So I kept watching.
Another tiny movement followed.
That settled the question.
This wasn't plastic.
It wasn't rubber.
It wasn't a wet piece of tissue or something from the drain.
It was alive.
The Mystery Suddenly Became Much More Real
Once I knew I was dealing with a living creature, my curiosity became much stronger.
Fear of the unknown is often worse than fear of something you can identify.
I wanted a name for it.
If I could figure out exactly what the creature was, perhaps I could understand how it might have ended up there and whether there was any reason to be concerned.
So I did what most people would probably do in that situation.
I took a photograph.
Then I started searching online.
At first, my searches were extremely broad.
I tried descriptions based on its appearance: small dark worm in bathroom, black worm-like creature on wet floor, strange creature near bathroom drain.
The results showed all kinds of possibilities.
Some looked nothing like what I had found.
Others were similar enough to make me wonder.
I kept comparing the photograph with pictures, paying attention to the shape, texture, and general appearance.
Eventually, one possibility began appearing again and again.
And the more images I examined, the more obvious the answer seemed.
The creature appeared to be a leech.
A Leech — Inside the Bathroom
Realizing that made the discovery feel considerably stranger.
Most people have heard of leeches, even if they've never actually encountered one.
They're generally associated with wet environments, particularly freshwater habitats. They belong to the same broad group of segmented worms that includes earthworms, although their bodies and lifestyles can be very different.
Some species of leeches are predators that feed on small invertebrates. Others are known for a behavior that has made leeches famous—or infamous—for centuries: attaching themselves to vertebrate hosts and feeding on blood.
That association was enough to make me look at the tiny creature on the floor with a completely different level of discomfort.
Finding an ordinary insect in a bathroom wouldn't have seemed particularly shocking.
A mosquito? Annoying, but normal.
A spider? Not exactly welcome, but understandable.
A tiny beetle or fly? Easy enough to imagine.
But a leech?
