Shame on the
BBC for its painfully small images.
Anyway, Mother Nature is a BITCH. One of the things she really goes gross on is parasites. I hate parasites but this one must be the worst.
This bug sucks the blood out of the tongue of a particular fish, until the tongue withers and dies and the bug actually replaces it. The bug attaches itself to the remaining stub and just sits there and gets a portion of everything the fish consumes.
Ew, foul!
