These Creepy Little Creatures Live Inside the Mouths of Fish, Replacing Their Tongue

Not much is known about what the louse is up to once its host dies. Maybe it gives up on life with the fish, but it’s also possible that it detaches from it and starts to look for a new home. However, we do know that the tongue-eating louse’s prime targets are snappers, but it was discovered within other fish species as well.

If you’re wondering whether these parasites are dangerous for humans, we have good news. The Cymothoa exigua poses no major danger to humans, except that it may bite your finger if you try to touch it.
