Size of Life

Pretty glad the 9 foot long Arthopleura centipede went extinct 300 million years ago. No one wants to deal with that thing.

We've still got this:

Thankfully they don't live on land.

It was a millipede, not a centipede, which probably ate fungi or decaying plants.

So it was not a dangerous predator, though it could have been poisonous, like many modern millipedes.

That's fresh nightmare fuel all right

Not really bothered by snakes, sharks or spiders. But those things (and cave centipedes) look terrifying.
