This shark, called a Japanese Goblin Shark, has a pop-out mouth inside its mouth. This video shows how it works. (Japanese language soundtrack.)

Awesome! I've never seen a vertebrate with jaws that did that. Wouldn't want to meet that little fellow on a dark night. :-)

(BTW, the Alien jaw mechanism was, I believe, actually inspired by dragonfly larva jaws, which have that popout mechanism too.)

I got the impression someone studied entomology and had nightmares they converted into the Alien script.

Yup
Moray Eels also have a second internal jaw, with teeth.

Yes. You get to meet these in the abyss on Endless Ocean on the Wii. Although they don't bite you (nothing in that game attacks you; you can pet a Lionfish or poke Great White without getting hurt).
