So if the world weren't horrifying enough for you, consider this: British scientists have discovered a symbiotic bug that eats tongues then attaches itself to the root of the former tongue and acts like a new tongue. The bug, Cymothoa exigua, feeds exclusively on fish tongues — thank God — and drains the tongue of its blood. Most surprisingly, the host fish doesn't necessarily suffer. The bug is so adept at mimicking tongue actions that the fish can continue to live with its squiggly new licker. So it's not a parasite. Just a new little friend.
It's like a helper monkey for fish, if the helper monkey rendered the person handicapped beforehand.
And I can't remember every having typed the word tongue so many times.
