I love the phrase going down a rabbit hole, but it got me thinking, do rabbits even dig that deep to begin with? And what organisms (besides humans) might dig deeper that might be even more fun to tweak that phrase with?...
I only know of earthworm that they have been found up to 7 meters deep. But the rabbit hole thing is definitely not about the depth but about Alice in wonderland and the strange things you might find down there.
What (non-human) surface organism tends to burrow the deepest into the Earth?
