25 Most Terrifying Deep Sea Creatures

Posted by on June 18, 2012

Although these days everyone is obsessed with zombies and aliens, some of the strangest and most terrifying creatures in the universe lie beneath the surface of the waves on our very own planet. In the pitch black depths of the ocean where the pressure can be dozens of times higher than at sea level you may very well find yourself running into one of these denizens of the deep. Allow us to introduce you to the 25 most terrifying deep sea creatures on Earth.



Although they are found at depths of nearly 2km, the Dragonfish actually starts its life at the surface of the ocean as a result of its egg being buoyant. Like many other deep sea creatures, it eventually becomes capable of producing its own light using a method known as bioluminescence after which it descends to the depths. One of its many light producing photophores can be found on a barbel attached to its lower jaw, which it most likely uses for hunting.


Frilled Shark

Termed a living fossil, this seldom seen shark inhabits the depths of the Atlantic and Pacific Oceans. Scientists speculate that it captures its prey by bending its body and lunging forward like a snake while proceeding to swallow its victim whole.


Vampire Squid

With the largest eyes (proportionally speaking) of any animal in the world, this deep sea creature is born to live in the depths. And no, it doesn’t suck blood, in fact its tentacles barely have suckers at all. The name actually comes from its intensely red eyes and cloak like webbing.


Big Red Jellyfish

This startlingly large jellyfish can grow to be over 1 meter in length and as you may have deduced from the fairly straightforward name, it carries a slight red coloration. Rather than tentacles this deep sea jellyfish uses a series of fleshy “feeding arms” to capture its prey.


Giant Squid

Seldom seen by human eyes, the giant squid has for centuries been a thing of legend. Dwelling deep beneath the waves its only real predator is the sperm whale. In fact, the two are famous for their deep sea battles and their carcasses are often times found bearing the marks of mortal combat on their bodies.



Primarily found in the deep water off of Australia and New Zealand the blobfish lives at depths of over 1200 meters. The pressure here is several dozen times higher than at the surface and as a result its body is little more than a gelatinous mass.



Resembling a pink, spine covered balloon these deep sea hunters are something of a cross between pufferfish and anglerfish (#12). Although they lure their prey using a fleshy protrusion they are capable of puffing themselves up when threatened.


Giant Isopod

Unlike the other creatures on this list, the Isopod is permanently constrained to creeping along the bottom of the ocean, primarily the cold, dark waters of the North Atlantic and the Arctic Circle.



With both their eyes and mouth located on top of their head, these fish bury themselves in the sand and leap upwards to attack their prey as it swims by. Moreover many species are electric and capable of delivering lethal shocks.



Not to be confused with the Chimera of Greek mythology, these creatures are also known as ghost sharks, and although they used to reside throughout the world’s oceans, today they are mostly confined to deep water.



Although these tiny crustaceans are usually no longer than an inch, deep down on the floor of the Pacific Ocean, about 6 km beneath the waves, they can grow up to 1 foot in length.


Pacific Blackdragon

This deep sea predator got its name for a reason. Because most of its prey are bioluminescent, their stomach is designed to prevent light from radiating through.


Dumbo Octopus

Named after the elephant in the Disney film, this octopus isn’t necessarily as terrifying as the frill shark but it’s far too strange to not include on this list.



Named after its hunting technique the anglerfish uses a fleshy growth protruding from the top of its head as a lure to attract its prey.


Gulper Eel

Also known as the pelican eel, this is probably one of strangest looking creatures lurking in the deep. With an enormous mouth it is capable of swallowing things much, much larger than itself.
