This scary looking tiny fish that needs little food to stay alive lives in deep oceans and its habits are still pretty much unknown for scientists, as it lives in deep oceans.
Japanese sea slugs, in particular, which have appeared on the coast of the United States a few years after the 2011 massive tsunami. The violence of the water washed them there.
Out of a horror movie, it comes this human face skin textured bizarre animal whose body has no muscle strength, so it eats merely opening his mouth and letting anything come in.
This pitbull inspired little fish has the largest teeth of any fish in the ocean (relative to its actual size) and lives as far as 16,400 feet beneath the sea.
Although this animal has no brain or sensory organs, it is vital for the development of oceans it lives in. The faceless animal also can mutilate itself to save from predators.
"A shark, that I know"- well, not this creepy face looking one. It is the last survivor of a 125 million-year old shark crew and maintains its features ever since.
Flamingo tongue snail
Compared to the previous in this list, this Pixar looking snails is even cute. But it is also very interesting: it eats toxic sea fans, absorbs its venom and suffers no harm.
The angler fish
This fascinating fish has a spine that grows a glowing mass, which he uses to capture his food. The shape of the teeth allows him to capture and chew easily in difficult dark areas.
This beautiful little being, which slightly resembles a smiley face, has a complex and fascinating process of aging and it was named after the Aztec word for "water doll", since it was found near Mexico.
Strange as it looks, this is an animal discovered no less than 13,000 and 23,000 feet. It can swallow its food whole, as it crawls on the ocean floor to find it.
This little one is only a few centimeters long, but can be found practically in every ocean, from 100 meters below. It has a large organ which produces a lighting fluid.
The mimic octopus
This 2 feet long striped octopus has a distinctive feature: it is able to mimic the movements and phisical appearance of at least fifteen species. It is a discovery of the early 2000s.
This glittering squid is 6 cm long and full of shine thanks to a cluster of organs that emit brilliant flashes of light. A billion of them die every year as a result of their life cycle.
This fierce-looking-look-alike master of camouflage lives in cold regions of some oceans and uses this special skill to look like part of the scenery to hunt and eat smaller fish.
Or as we like to call it, Synanceia horrid. This fish lives in Austrialia and is considered one of the most venomous of fishes, even fatal for humans (although there is an antidote).
As straight out from an Avatar fantasy as it may seem, this warm sea inhabitant actually exists. It has its body covered in colorful scales that change as they move from infant to adulthood.
The black swallower
Someone didn´t get too creative with this little fish´s name but in compensation, Nature gave it the ability to eat and process things that are up to 10 times bigger than its body.
It is still very little what we know about this one, although it has been recorded that it has more nocturnal habits, which led them even into the nets of fishermen, while is really quiet during the day.
First observed in 1976, it is a type of shark that sets aside from the rest because – of course – of its massive mouth which uses to swallow small fish and plankton… pretty much like whales look and do.
Blue ringed octopus
If you look closely at the picture, you can find one of this octopus eyes, mingled into the blue circles that cover its body. It is one of the most poisonous animals in the ocean and still an antidote for its venom hasn´t been found.
Also known as Spook Fish, this adorable rounded fella has eyes that move to scan for food and live under this sort of transparent dome that surrounds them and gives them a unique aspect.
Not so good looking but full of strategies to hunt hundreds of meters below the surface: it creates its own light to search for food, even in dark deep waters – that´s also the reason for its poppy eyes.
With an enormous mouth that resembles the one of a pelican, this animal can swallow things that are much bigger than itself. When in hostile places, species are forced to develop tactics and parts of their body in order to survive.
Tiny as it may seem, this animal feeds of other animals which are luminescent, and it is a true predator. The skills to mix with the environment and to achieve prey anywhere sharpens as the conditions are more hostile.
Or ghost shark. With an appearance that seems to hace mixtured a shark and a squid, these animals which lived in every ocean are now confined only to deep waters.
The small dimensions of this crustaceous – an inch at birth, yet they can can grow up to 1 foot in length – make its looks even more incredible and led us to wonder the mixture of species it might carry in its genes.
Although this fish main hunting technique is to hide under the sand looking up to attack its prey by surprise, often it gives electrical – even lethal in some cases- shocks.
This white Isopod walks along the surface of the ocean basis only, and as it lives in the depths of the North Atlantic and Artic Circle waters, its colour gives the chance to maintain a low profile.
When it comes to these rare creatures, it seems that naming after objects is a thing – so, the fish that looks like a coffin (and that can puff itself when threatened).
Pink see-through fantasia
One of the strangeast of the already strange sea cucumber family, this one lives about a mile and a half deep in the Celebes Sea in the western Pacific (east of Borneo).
Also found in the Celebes Sea (East Borneo), this creative mix of Mother Nature is as rare as it is beautiful, with its puffy lines, shiny colors and squid and worm resemblances.
Christmas tree worm
Yes: this IS an animal and actually exists, at the Great Barrier Reef´s Lizard Island, one of the world´s most complete ocean life resources: the "branches" are its breathing system.
A new definition for rare, this white and see through snail family member, lives in the Artic ocean waters and "flies" along them to find smaller snails to feed from.
It is the official name for this microscopic thing, that might as well have been named after a rocket. With multiple tentacles and multiple stomaches, constitutes one of the most fascinating designs under the sea.
This creepy looking squid which lives in Monterey bay seems to deserve his name, due to his color and piercing eyes. Who would have thought that there were such diversity between squids?
Living in the southwestern coast of Australia alone, the leaf-alike parts at the end of this seadragon extremities makes it a better swimmer as well as an excellent camouflage artist.
Crossota Norvegica Jellyfish
Jellyfish are plenty and every one intriguing in its own way, but this one – found at the deep Arctic Canada Basin – certainly wins our attention with that luxurious red case.
The furry- claw crab that you will think of the next time you order crab. Also known as God of Shellfish, it was found 5000 feet below in a thermal environment, south of Easter Island.
Who would have imagined that a worm that eats the dead body of the whales at sea could be of such beauty? That´s its job and it is found in Sagami Bay, Japan.
This funny looking little guy also acquired a much obvious name but its shape is not obvious at all. Living in southern Australia and Tasmani, it grows to around 15cm.
The tactic for this shark, whose diet consists on fish, octopuses, crabs and lobsters, is to lay low like a carpet on the floor, mixing itself with everything around to surprise the prey.
This fish contains anti freezing in its veins and no red cells, that is why it is so adaptable to the cold waters of Antarctica (although, unfortunately, it lives in one of the fastest warming seas on Earth).
This is yet another member of the sea cucumber family, which lives in the coast of Antarctica and who is important to process the sediment. They are good indicators of climate change.
These arthropods can grow very much if happen to find a spot with no predators and good oxygen, although they are also endangered species because of the warmth of the waters where they live.
Some feeling of an ancient fossil comes to our imagination when first looking at these crustaceans. The image shows one of these tiny animals, both viewed facing up and down.
With its beautiful intricate design, this star wins a place for itself among the strangest creatures of the sea. It has the ability to float on water or swim underneath.
Another marvelous looking jellyfish that seems like a transparent brain… or a plastic bag. They live in great communities on the Southern Ocean surface and can resist the warmth of their waters.
This is a species yet to be identified, but at plain sight it stands out from the other corals for the soft rounded shape of its body, looking more like a flower.
Funny looking, still not pleasing to find as their tiny mouths can chew jellyfish and their small size and quick adaptation to warm waters have helped them avoid extinction so far.
As small as it gets, this is a radiolarian protozoa, which is a type of microscopic organism, composed by a fragile skeleton and identified for its distinctive shape of a mandala design.
