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.
For fun, Fedortsov shares photos of the unusual creatures he catches, whether a ghost shark with glowing eyes or an alien-esque underwater spider.
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.
