Fishing linked to higher percentage of tongue-eating, blood-drinking mouth leeches from Hell
Isopods are crustaceans (like lobsters). Some isopods are parasitic (like the one staring back at you in the picture up top). If you’re having trouble making out what, exactly, this isopod has parasitized, the answer is: a fish. This little monster wriggled its way in through the gills of its host, implanted itself inside the fish’s mouth, and gorged itself on its victim’s tongue — which it has now effectively replaced. Permanently.
