Uncharismatic Fact of the Day
Louse got your tongue? No, it's the tongue-eating louse! As its name implies, this isopod is a parasite of fish; females latch onto a fish's tongue and cut off the blood vessels until the tongue falls off completely. The female tongue-eating louse then takes the place of the tongue, helping itself to any food that the fish might eat, as well as mucus produced in the fish's mouth.

parasites are great, we love parasites. but i had 3 of these fucking things attached to my skin when i exited the ocean & i can't ID them. there could be more in other crevices that i won't discover until i get back to my hotel. the germaphobic & parasite-loving halves of me are fightingggggg
