GALVESTON, Texas – We know it’s the spooky season but a tongue-eating parasite is apparently a real thing and it was recently found inside a fish at Galveston Island State Park.
A tongue-eating louse was found inside the mouth of an Atlantic Croaker this week and officials with the Texas Parks and Wildlife Department took a photo and shared it on Facebook.
The alien-like parasite actually detaches the fish’s tongue before attaching itself to the fish’s mouth and becoming the tongue.
“Tongue-eating louse or ‘snapper-choking isopod’ are somewhat common among certain species of fish, like Atlantic croaker, spotted seatrout, and a few species of snapper,” said Coastal Fisheries Science Director Mark Fisher. “These are isopod crustaceans and are related to the pill bugs, aka rolly-pollies, you can find in your yard.”

The parasite feeds on the fish’s mucus but it does not kill the fish or affect humans, officials said in the Facebook post.
They also said it’s the only known case of a parasite functionally replacing the organ of its host.
“It can be a surprise to peer into a fish’s mouth and have another set of eyes looking back at you,” said Fisher.
