Think giant sharks are scary? These Mariana Trench creatures will really scare you to death. What could be more terrifying than the prehistoric giant sharks that once lived in the Mariana Trench, now inhabited by creepy creatures with sharp short teeth, and while the Mariana Trench has not yet been fully explored, the creatures scientists have discovered so far are frightening enough. Read on to learn about the amazing underwater creatures in the deepest waters in the world, but after watching it you may never want to swim in the sea again, or you may not want to dive into deep water.

10. Fangfish (horned high-body goldeneye snapper)
The name is a bit weird but it is a creature that lives in the Mariana Trench, which is between 10,668 and 11 km under the sea. Considering how deep it is, although scientists are aware of the existence of the Mariana Trench, it is also the least explored place in the world. This is the deepest part of the ocean, and many of the creatures in the trenches have not yet come into contact with humans, but scientists also know something about the fangs, and the name of the fangfish is defined by its characteristics. Fangs are carnivores, as long as the absolute devoured bones in his mouth are gone. Fangfish rely on biological receivers to find their prey, in other words, they can feel the biological information released by other organisms in the deep sea. The reason why the fangfish do this is because unlike other deep-sea fish they have no luminous cells, and the seabed is dark, so as long as there are creatures touching them, they will not be merciless, although the fangfish look abominable, but harmless to humans, they will only grow up to 18 centimeters, even so, I would not want to touch them when swimming in the sea.
9. Dumbo octopus
Dumbo octopuses may look cute at first glance, but they devour their prey alive, and they have no teeth, so they mostly hunt invertebrates on the surface of the sea. Dumbo octopus got its name because it resembles a cartoon character, with elephant-like ears, a 30-centimeter-long body and wide-eyed eyes! According to the International Ocean Conservancy, as far as scientists know, dumbo octopus is an octopus that lives in the deepest part of the sea. They are also known as umbrella octopus because their arms are connected by a net of objects, which open like an umbrella, and are indeed slippery and hungry deep-sea umbrella octopuses.
8. Pacific barrel-eye fish (tube-eye fish, large-finned posterior analfish)
This special fish lives in the 762-meter-deep Mariana Trench, and their special and frightening body structure is unique to the bucket-eye fish. For example, the transparent head, you can see through the head of the barrel-eye fish, and some scientists believe that this allows the barrel-eye fish to get a little light in the deep sea of black pressure, making it easier for them to hunt than other fish that feed in the dark. The barrel-eyed fish have two barrel-shaped upward-looking eyes in their heads, allowing them to clearly see the outline of their prey. Although scientists already know what the bucket-eye fish looks like, its breeding patterns and life cycles have yet to be explored.
7. Sea devil squid
This creature doesn't look like it came from Earth, but rather like a creature from a horror movie. The Sea Devil Sturgeon lives in the deep sea at a depth of 975 meters and has strange appearance features such as sharp knife-like teeth, deformed bodies and troublesome eyes. But perhaps the most harmful is the way they catch their prey. The Sea Devil Ankon has a fishing rod on its forehead and a luminous appendage at the tail end that is used to attract animals to the door. Once an animal is too close to the light, it becomes their food. Sea devil sturgeon have huge jaws, and they can even eat prey that is larger than their size, so their eyes are no bigger than their stomachs.
6. Goblin shark (Euclidean harp shark)
If you think the movie Jaws are scary, the Goblin Shark will make you swear never to go into the deep sea. But they live at a depth of 914 meters, so you probably won't come across them. Goblin sharks look like a combination of sharks and creatures in your nightmares, with an arrow-like snout and jaws that are unique. The general shark has a greyish hue in color, but the Goblin Sandsa is pink, but it is not as beautiful as you think. And apart from their harmful behavior, what do scientists know about them? Not much, but it is known that they can grow up to 5 meters long.
5. Deep-sea axefish
Do you know what looks like a small axe tool? That's how the name of the deep-sea axefish comes from. There are more than 40 species of deep-sea axefish in the world, all of which are flat and shiny scales, which is why they have a metallic appearance. Deep-sea axefish can grow to about 15 cm long, but they have a very high tolerance for water pressure, so they live in the sea at a depth of 1542 meters, fortunately, their self-luminous properties, the degree of their luminescence changes with the amount of light entering the seabed, so it is easy to camouflage on the seabed and lure prey to the door.
4. Bone-eating worms
Bone-eating worms are not half-dead deep-sea creatures, they are living creatures, and they are also called worms because they can swallow the bones of giant mammals, such as whales. Bone-eating worms dissolve nutrients in bones by secreting acidic substances. They also breathe oxygen from the sea through their squirming bodies.
3. Deep-sea dragonfish
If there is a race against the ugliest fish on the bottom of the sea, then the champion is definitely not the deep sea arowana. They are slippery, have no scales, have a mouth of huge teeth, look like only their mothers, and have a bad temper. They like to swim 273-1829 meters under the sea, which is also the darkest and coldest place in the sea. Like the creatures in the other films, the deep-sea arowana catches prey through its own glow, and they emit a red light at the end of an appendage that protrudes from the jaw, and many fish mistake the red light for prey, but swim into the mouth of the deep-sea arowana as soon as they swim forward.
2. Frilled sharks
Studying the wrinkled sand is like traveling back in time to prehistoric times, because scientists believe that this eel-like shark has not changed since its appearance, so they are sometimes called living fossils, and these sharks have 25 rows of back-facing fangs in their mouths, with a total of 300 teeth. According to an 1884 study published in the journal Essex Agency, the teeth were used to catch prey and hold firmly to prevent them from escaping. But if you like to swim, don't worry, because the frilled shark lives 119 meters to 1280 meters under the sea, and you can't meet each other.
1. Slippery Tooth Dragon
Most of the creatures described in this article are still alive, but some of the most frightening creatures, such as the megalodon shark, are long extinct. However, if we do not introduce the list of prehistoric creatures of Slippery Tooth Dragon, it is not complete. This carnivorous, marine reptile lived during the Middle Jurassic period and dominated the 2.7-meter seafloor. Scientists believe that the reason why The Slippery Tooth Dragon is active in the Mariana Trench is because they can travel long distances and paddle-shaped limbs, they may not be able to pounce on their prey like other creatures in the deep sea, but they are still able to sprint and attack effectively. In addition, they sniffed out smaller prey with their proboscises, so scientists also believed that they did not rely on visual hunting, and could probably speculate how they survived in the dark Mariana Trench. About 150 million years ago, " Slippery Toothosaurus " became extinct because it couldn't compete with other active submarine reptiles for prey.
Given that scientists have only explored 5% of the Mariana Trench so far, and have discovered so many unimaginable creatures, one can't help but wonder what other strange creatures are there?
