Ok one more, I can't help myself.

This one isn't really a manipulative parasite, but there is an isopod that will eat a fish's tongue: https://oceanconservancy.org/blog/2022/04/28/tongue-eating-l...

What's weird is that it then... basically acts like a tongue? It doesn't seem to be massively detrimental to its host, but it's absolutely insane to see a fish's mouth open and then there's just like, a little guy hanging out in there.

Jesus fuck. I knew about these guys but did not know they perform this by hanging out in fish gills until they get a breeding pair, them one crawls from the gills to the tongue to clamp on and replace the damned thing, and later they reproduce and spread young from the gills!
crazy, and terrible!!!
