Some people don't like the idea of worms and actively avoid them. I'm not one of them but I know several people that are. The idea of chilling on a pristine glacier somewhere and suddenly finding yourself surrounded by thousands of worms is pretty unsettling to the worm avoidant.

Naturally I introduce these people to the existence of the Giant Palouse Earthworm [0], also in the Pacific Northwest, though these are so rare that it would be of scientific interest if you came across one.

clear scoleciphobia if I've ever seen it
