Most of us will never know firsthand what bizarre creatures lurk in the deepest parts of the ocean, but if you're willing to risk a few sleepless nights you can always gawk at the horrifying photos on fisherman Roman Fedortsov's Twitter feed and Instagram account.
Fedortsov works on a fishing trawler in Murmansk, Russia, and regularly comes in contact with deep-sea dwellers that look like the kind of weird creatures filmmaker Guillermo del Toro would design.
Most seasoned fishermen have had their share of odd catches, but to the rest of us, these deep-sea creatures are the stuff of nightmares. Even a shark from "Jaws" looks tame compared with some of these spiny, eye-bulging, slimy, evil-looking sea species that will probably make you take a permanent break from eating sushi.
Don't say we didn't warn you.
