Life is strange in the deep ocean, and the animals that dwell in its pitch blackness are like nothing else on Earth. The only light that illuminates the abyss is the bioluminescence of the organisms that live there. That's a good thing, too, because many of them are absolutely terrifying to behold.
Some of these monstrosities are gargantuan in size, as life in the deep sea tends to make animals larger. Meters-long tentacles, enormous teeth, and prodigious jaws are all common near the ocean floor. These are the creepiest sea creatures in the deep ocean, and once you realize they're down there, it may be difficult to step into the water again.
This gruesome creature is best known for the glowing lure on its head, which it uses to entice its prey. Since food is so scarce in the depths, the anglerfish has an unusually large belly designed for food that must be swallowed whole.
In many species of angler, like the humpback anglerfish, the females grow to sizes much larger than their male counterparts. In fact, male anglerfish look almost nothing like the females. They are small and nondescript and exist for the sole purpose of finding a mate. If one is lucky enough to find a female, he bites into her flesh and becomes a parasite that feeds off her blood.
In some species of anglerfish, the male remains attached to the female for the rest of his life. Fused to her body, his eyes and organs atrophy until he becomes nothing more than a reproductive tool.Is this terrifying?

Found at depths of over 1,000 feet, these crustaceans are believed to live up to 100 years. The spider crab is a delicacy in Japan, which has contributed to a significant decline in its population.Is this terrifying?
