If you enjoyed this fun fact, start reading The Laundry Files by Charles Stross. Once you get to book 4 come back here and thank me. Tongue eating isopods from beyond the stars play a role there, and appear briefly later in one of his New Management books, although I don't have the page handy so I'm not sure which one.
Their nastier cousins make an appearance later in the Laundry Files, but I'll leave what they do a mystery.
If you like making fun of quiverfull ministries, programming, Eldritch horrors, British humor (humour?), spy thrillers, agitated engineers, vampires that don't exist, bloodthirsty elves, and a thinly veiled story about anthropomorphic climate change then this is the series for you.
