This is one of the craziest things I’d ever heard of, and I spent the entire rest of the day after learning this being super excited (and slightly terrified) about it.

If you can’t read my handwriting, this is Epomis dejeani. There are all kinds of crazy videos of these things taking down frogs and toads (you might not wanna watch if you’re squeamish, they get a bit gruesome). In that last link, the frog eats the larva, which continues moving around inside it until the frog spits it up two hours later, at which point the larva turns around and eats thefrog HOLY CRAP

Also did I mention the adults actually paralyze their victims? Scientists aren’t even sure how they do it— they bite the back, but the spinal cord is actually intact

So yeah, that’s freakin nuts. Here’s an article with more information on this ridiculous species. I STILL can’t get over this.
