There are no ghosts in the microcosmos.. There is no Halloween in the microcosmos.. But if there were, this flatworm would fit in quite nicely with its spectral appearance.
It might be navigating its way through a field of other organisms, but it looks like it had
three minutes to prepare for a costume party and decided to go with the classic “old
bedsheet with eyeholes” ghost costume.. And maybe comparing this flatworm (or even worms in general) to a ghost is kind of apt.
Ghosts straddle two worlds, and so do worms, though in their case, instead of bridging
the realm of the living and dead, worms manage to stretch between the micro and the macro.
This creature you’re watching now would probably be difficult to see without a microscope.
But on the other end, there are worms that are meters too long to observe with a microscope.
And akin to ghosts, worms might seem like a sort of reduced form of life.
After all, for a lot of us, worms are the wiggly tubes that we dug up from playgrounds.
And of all of the worms, flatworms are perhaps the most simple of all.
But even digging into what it means to be the simplest worm makes the whole notion of
simplicity seem ludicrous.. So let’s start with the broader question: what are worms, other than wiggly, self-mating tubes?
