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.



There aren’t many ways to describe this deep sea critter that don’t include the words “very ugly”. Like several other species on this list, due to the fact that it lives at such depths, it’s capable of producing its own light and uses this ability to hunt its prey.



Not to be confused with the freshwater hatchetfish found in many home aquariums this species was named after the distinctive hatchet shape of its body. Living at extreme depths it has two tubular eyes that point upward enabling it to catch food falling from above.



Also known as spook fish, these strange looking creatures are similar to hatchetfish in that they have two upward facing eyes to scan for prey. Their distinctive feature, however, is the transparent dome that encases them.



One of the more abundant bottom dwellers, grenadiers have been estimated to make up about 15% of the deep sea population and found at depths of up 6km there are few other creatures that can survive in such hostile environments.


Blue Ringed Octopus

Although it may not be as physically imposing as some of the other creatures on this list, the blue ringed octopus is easily one of the most dangerous animals in the ocean. It’s venom is extremely potent and because there is no antivenin, it is certainly a good idea to steer clear.
