Forget being afraid of the dark — there aren't any monsters under the bed. They're all lurking under the sea, miles below the surface, waiting for whatever unfortunate food falls victim to their razor teeth and sticky tentacles. These rarely-seen, prehistoric looking creatures are both terrifying and fascinating, and little is known about their alien ways.
Meet five deep-sea species that make spooky nighttime ghouls and zombies look as scary as Sesame Street's Cookie Monster.
1. Deepstaria Jellyfish
In May, this video (below) of a mysterious deep sea creature circulated the internet. As the billowy being drifts across the underwater camera at a startling depth of 5,044 feet, we catch a glimpse of the unknown. Is it an alien? A jellyfish? A trash bag? Scientists later confirmed that this ghost-like creature is, in fact, a rarely seen jellyfish called deepstaria enigmatica, first discovered in 1967.
