“Shapeshifting vampire demon anchovy”

Do you need more than that headline to pique your curiosity? How about the fact that it sported a single saber tooth on top and razor fangs on the bottom?

We won’t talk about the thing that’s eating it.

They named it “Monosmilus chureloides” which roughly translates to “single knife Churel,” and it’s a newly discovered ancient fish (from about 45 million years ago) that lived where Pakistan is today. Churel? Yeah, that would be a mythical “ghost of an unpurified living thing” from southeast Asian folklore. But this fish was real.
[It] had 16 fang-like curved teeth on its lower jaw that were small in the back and “progressively larger towards the front.” The longest fang was 0.8 inches (2 cm), or about 20% the length of the whole head.
