Everyone likes sea, really. Nothing better in life than to take a dip on a sunny day, chillax and have a good time. But when you see this list, you’ll surely keep away from deep water 😀


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.

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.

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.


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

Giant Isopod

Unlike the other deep sea 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. I wouldn’t like to see this crawling around my legs.

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.

Gulper Eel

Also known as the pelican eel, this is probably one of strangest looking deep sea creatures. With its enormous mouth it is capable of swallowing things much, much larger than itself. Nasty bite!

Blue Ringed Octopus

Although it may not be as physically imposing as some of the other deep sea 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 antivenom, it is certainly a good idea to steer clear.

Megamouth Shark

Since its discovery in 1976 this extremely rare species of deep water shark has rarely been seen by human eyes and as of yet there is still no consensus in the scientific community as to how to actually classify it. It’s most distinctive feature as you probably guessed is its gaping mouth that it most likely uses to swallow plankton and small fish. MEGA MOUTH? I suppose, it can fit a whole person in it :/


Another quite unpleasant-looking. While during the day this scary sea animal stays in deep water, at night it has been known to venture into shallower territory and into the nets of deep sea fishermen. They don’t survive very well in captivity, however, so not much is known about them, although their appearance certainly earns them a spot on this list.

Goblin Shark

Not much is known about this deep sea dweller as only a few specimens have ever been caught by fishing boats, but those rare catches have been enough to earn it a fearsome reputation. With a prominent snout and retractable jaws its physical characteristics are worthy of its name.
