Everything in the ocean is always so mysterious, for now, only 5% of human understanding of the ocean is known, and the rest is still completely unknown and unfamiliar territory. What exactly is below sea level?
What is certain is that there are countless weird creatures... Many strange creatures are no different from "alien visitors".
In a way, the ocean is the closest place you can reach to an "alien" without leaving Earth.
Eye lamp fish, the biggest feature of this fish is that they have a glowing part under their eyes, like the big eyes of aliens? In the dark deep-sea environment, they are often in groups, and they are also known as the "deep sea milky way".

Bucket-eye fish, a fish with its own transparent flight module, its most magical place is that it has a transparent cover on the top of the head, and the eyes are completely wrapped in the cover, which can move freely inside, and the two black dots above the mouth are actually nostrils.
Swallowing eel, also known as wide-throated fish, it lives in the deep sea of about 2000 meters, the most unique place is in its mouth, usually closed, when preying, it will open a huge sac located on the head, swallow the prey and seawater together, and then drain the water from a hole in the back of the head, and then swallow the food in the stomach, and then it is back in the strip.
Not only are marine creatures strange, but even their eggs are not ordinary, this long thing like an electric drill screw head is like a part of the earth left by an alien flying saucer, in fact, this is the egg of a tiger shark, such an alien can effectively attach to the stone crevices to avoid predators.
And this UFO-like "deep-sea flying saucer", shaped like exploded fireworks, is amazingly beautiful, this kind of jellyfish that emits ghostly light is called halitrephes maasi, which is known as "firework jellyfish" in China.
Crossota jellyfish, this slender leg, round head, fits perfectly into many science fiction ideas.
The strange shape of the jellyfish was once mistaken for the placenta of marine mammals, and the body was like a bag, and the way to hunt was to put the prey in, so it was called the placental jellyfish.
The leafy seahorse, this strange seahorse that lives in the western and southern waters of Australia, when still, is like a branch that has fallen into the water.
The Christmas tree worm, a very colorful and specially shaped marine worm, scientifically known as the Great Spiny Gill, usually lives in tropical seas and lives in symbiosis with corals.
This thing that looks like a human painted craft is actually a snail! Because it looks like the tongue of a flamingo, it is called a flamingo tongue snail.
The giant sea scale insect, a creature that has not yet evolved its eyes, is most amazing about its huge mouth and teeth that are exposed when the pharynx is turned outward.
Sea angels, marine mollusks that live in the deep seas of the Arctic and Antarctic, are not only sci-fi, but also hermaphrodites.
Tube jellyfish, some bodies can be tens of meters long. It looks like a creature of another world, and the part of the picture that resembles a string of firecrackers is its attached "air cell sac", which occupies only a small part.
Some time ago, a tube jellyfish was photographed on the coast of Australia, floating in the water like a ghost, the length of the outer ring alone is 47 meters, and the overall length is currently estimated to be more than 120 meters!
The Great King's Footworm, a giant isopod found in the deep sea, resembles the monsters in horror science fiction movies, but is edible and tastes like shrimp and crabs.
The sea gills, which look like a feather, are an invertebrate, beautiful but also poisonous.
Especially in the deep sea creatures, no one can see anyone, and the appearance becomes very casual! There is such a warrior fisherman of the fighting nation, Roman Fedortsov, who likes to put all kinds of strange fish on his social account, the shape is strange, most of them don't even know the name to feel together:
The ghost in the fish is you...
This one is actually a bit cute...
This item can no longer be called a fish. But I don't know what to call it.
This tm is a monster!
This is still normal...
Strange looks that you can't dream of,
Not to mention the Cthulhu style, or the alien style octopus...
Finally, this is a deep-sea squid found in the Alaminos Gorge, which lives in the deep sea below 7800 feet...
Could it be that the legendary aliens are actually creatures under the sea....
