Want to learn about a truly horrifying parasite? Meet the tongue-eating isopod. This small crustacean swims into a fish's mouth, devours its tongue, then attaches itself where the tongue used to be.
The fish survives, essentially growing a "new tongue" made entirely of parasite. The isopod feeds on the fish's blood and mucus while living comfortably in its host's mouth as the fish continues its normal life. The tongue-eating isopod is the ultimate identity thief.
Next time you think your life is stressful, remember that somewhere in the ocean, a tiny crustacean is living inside someone else's mouth, drinking their blood, and pretending to be their tongue. I'm grateful there isn't a parasite that does this to humans—I'd spend my entire life in a hazmat suit. 00:00/11:46 10
