Scary deep sea creatures are often the stuff of nightmares, and rightfully so. 95% of the ocean remains unexplored. Fear of the unknown compels us to speculate on the weird deep sea creatures lurking in the frigid depths, where light cannot reach. We imagine that only abominations could survive the colossal pressure and utter darkness of the Mariana Trench. While some cute-looking precious creatures have been discovered recently like the dumbo octopus (much to the Internet’s joy), others like the black swallower are far more haunting and horrific. This deep sea creatures list is visually compelling as it guides you deeper and deeper into the darkness, introducing frightening and creepy critters along the way.
