The Terrifying Tongue-Eating Louse is a parasitic isopod known for its gruesome behavior. This small, marine crustacean attaches itself to the tongue of a fish, eventually replacing it by feeding on the blood and tissues. The louse effectively becomes the fish's new tongue, allowing the fish to survive, albeit with its parasitic invader in place. This rare and horrifying phenomenon showcases nature's more disturbing adaptations.
