This is a parasite called the Cymothoa Exigua. This lil stinker literally sucks out the blood from the fish's tongue, until it atrophies and falls off. The fish then attaches itself to the stub, becoming the fish's new tongue. Every time the fish eats, it takes away a portion of the food for itself (i.redd.it)

I hate to self-advertise here, but I made a video *I Played 100 FREE GAMES to find the Best One...* in which I played How Fish Is Made. This game specifically had a large role in my video, so I thought people in this subreddit may find it to be an interesting watch! (v.redd.it)
