Tongue-Eating Louse

The tongue-eating louse is a parasite that enters a fish through the gills and attaches itself to the fish's tongue. After severing the blood vessels in the fish's tongue, the tongue just falls off. It then attaches itself to the stub of what was once its tongue and becomes the fish’s new tongue. Fish companies do look for these parasites, but sometimes they slip through the control system. A Belfast man had the shock of his life when preparing his dinner. When he was cleaning a fish, its mouth opened and the disgusting looking tongue-eating louse popped out like the tongue of the monster from Alien.
