This creepy crawly was found living in a toilet in Brussels. Help me solve the mystery of what it is and how it got there. Is it a parasite? Hookworm, or roundworm? I have not used the toilet for defecation and only a couple times to urinate in months, so I suspect this thing possibly came in from the Brussels city water supply as an egg, hatched, and grew to be quite long before I noticed.
