Actually, that was a small catfish.

I stand corrected. I had heard different accounts while I was down in South America and for some reason a flat worm swimming up your urethra sounded more plausible than a catfish.

My unit in the USAF took that fish as a mascot, and we named our softball team the “Helmet Cats”; because that was the nickname we came up with for the Candiru based upon its relation to catfish and its point of entry.
