The first Alien film premiered 40 years ago, and the franchise is still going strong!

But science fiction is inspired by reality. Five viper dogfish sharks were found on the shores of Taiwan...

And they look frighteningly like the infamous Xenomorphs.

The viper dogfish, or Trigonognathus kabeyai, live 1,000 feet underwater...

But they can go up to 500 feet during the day.
