Eel vs. Alien

Quiz: What animal has a second jaw inside of their mouth to eat its prey? Sound like something from a movie? ....

If you immediately thought of the Alien from Ridley Scott's Alien movies, you're not too far off.  The Alien was inspired by this real animal with two jaws!

The answer is the Eel! Seriously, eels have rear-facing jagged teeth with their front jaw so that prey don't escape. The second jaw then comes out, bites the prey, and pulls it down the eels throat!!! This is so cool!

Here's a fantastic video by the Smithsonian Channel showing this in action:
