How do worms dig their tunnels if their body is soft?
In: 7923
Worms are so fascinating. I started worm composting right before the pandemic started. It’s crazy watching worms turn food waste into perfect black soil. I even took it so far as to design my own worm compost bin – called the [Worm Bucket](https://www.wormbucket.com).
What people mean by “worms” cover several species. So, most answers on this thread are technically right even if they are completely different
There seems to be two different answers in the comments. They expand and contract/use muscles and hairs OR eat the dirt and poop it out.
Which one is the right one?
