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?
Edit: Specified in title/body that I had meant to ask about non-human organisms. Still, there’s some cool info about deep human digs in the comments below for digfolks!
A species of fig (Ficus, family Moraceae) from the Transvaal of South Africa was determined to have roots reaching at least 122 meters - source, google fu
I think the phrase down the rabbit hole is actually referring to Alice in Wonderland. But.
I would say the organism that tends to burrow the deepest into the Earth is humans. Average oil well depth appears to be around 5,964 feet (1818 meters), that’s pretty deep. The deepest hole we ever drilled is supposedly the Kola Superdeep Borehole dug by the Soviets, it was 40,230 feet (12.2km) deep.
Perhaps not answer your looking for though.
Oh, that’s a fair point on both counts, I should have specified non-human organisms. Still, we’re apparently really good at digging deep holes, so that’s fun!
