15 Mariana Trench Creatures That Are Scarier Than Megalodon

the dark and high-pressured environment of the deepest place on earth the mariana trench means that not only is it incredibly difficult to explore frilled shark is one of the most bizarre-looking creatures on the planet but the animals that live down there have to adapt to an extremely hostile environment virtually every time an expedition goes down there something new is discovered and countless organisms have been found that are the stuff of nightmares here are the 15 Mariana Trench creatures that are scarier than Megalodon number 15 pliosaurus living in the ocean depths between 150 and 145 million years ago the pliosaurus was the first type of plas or to ever be discovered and named and it showed us quite how dangerous the prehistoric waters truly were there are nine known species each of which has slight variations to one another but there was one commonality between them all they were huge and terrifying thought to have grown to a length of around 50 feet their skulls along were longer than six feet most of which was made up of a giant mouth that was lined with sharp 12 inch long triangular teeth this would have been perfect for hunting the large fish squid and reptiles of the time but was also instrumental in their ability to defend themselves against other ocean predators to put this into perspective had a human being swimming near a playas or it would undoubtedly have been able to bite and swallow them in one gulp with a similar attack method as alligators use underwater today this is one monster we're fortunate doesn't still roam the oceans as far as we know because if they did the waters wouldn't be safe for anyone before we go on like this video smash the subscribe button and click the notification bell right now or Slenderman will come from under your bed when you're sleeping [Music] number 14 the fangtooth the fangtooth is a bizarre deep-sea fish whose Latin name Ana plug Astri day literally translates to mean unarmed stomach they are one of the deepest known living species of fish having been found below 16,000 feet in trenches around the world and have some unusual adaptations to allow them to thrive in these conditions the six inch long fish has the largest teeth of any known marine animal relative to their size and their fangs are so big that they can't ever fully close their mouths and a fifth to body size these are the largest teeth in the ocean they even have grooves on the side of their heads to allow the lower teeth to sit in position while not being used and to prevent them from damaging themselves but when they're on the hunt these proved to be viciously effective weapons with tiny eyes and no light available to see their prey they rely on their other senses to determine when a meal is near by they float in the water waiting for the opportune moment and then snap their jaws impaling small fish and invertebrates on their fangs amazingly this is the only species of deep-sea fish that has been able to be brought to the surface and be kept in aquaria despite the conditions being so different to what they're used to which just goes to show how adaptable the fangtooth actually is number 13 the Dumbo octopus there are hundreds of different species of octopus across the globe but the one that lives in the deepest depths is affectionately known as the Dumbo octopus they're just as highly intelligent as any other but they get their name because of their unusually positioned fins which almost appear to be giant ears like the elephant from the Disney movie they even use them in a similar way to the famous pachyderm they have been found at least 13,000 and 100 feet beneath the ocean surface and are thought to be able to survive much lower down where they flap their fins to propel themselves through the water feeding on any small creatures that they come across look at those ears because they live in such an inhospitable environment Dumbo octopuses don't have many natural predators and therefore don't have protective ink sacs like other species do they are very rarely seen or caught in Nets so their lifecycle and size aren't fully known but one specimen was found to be almost 6 feet long meaning it could easily wrap itself around a human if it came face-to-face with one number 12 the barreleye fish often commonly known as spook fish barreleye fish are some of the most unusual animals in the ocean they live at depths of at least 8,000 feet and have developed an ingenious way of detecting prey and predators macro penis sits quietly in the water using its big fins for stability their heads are covered in transparent skin so you can see their brains and eyes in a level of detail not possible with any other species the reason for this is quite remarkable because they're actually able to change the orientation of their eyes and move them from looking forwards to looking directly up this offers them a significant benefit not only can they see what's ahead when searching for food but they're also able to make out the shadows of prey or possible predators that are swimming above them they have exceptional eyesight for a fish with large lenses and a huge number of rod cells inside which are what allows eyes to detect and process low levels of light for some reason these fish are often found with bioluminescent bacteria in some of their organs that mean they emit flashes of light as they're swimming it's not entirely clear what purpose this serves but it has been suggested it's a way for them to meet a mate in the sparsely habituated depths when they might go for days or weeks without seeing another living organism number 11 the sea devil angler fish sea devil angler fish are a small but frightening looking species that live across the Atlantic Indian and Pacific Oceans at depths of at least 10,000 feet as with all angler fish the females are significant larger than the males because of their unique mating habits the Sea Devils will typically grow to around seven or eight inches long in the darkness of deep water they flash the light to attract the prey they are in key black in color which helps them blend into the low-light environment and have a large mouth full of razor-sharp teeth again as with other species their dorsal spine has adapted to hang out in front of them like a fishing rod and a structure called an Eska dangles on the end that's full of bioluminescent bacteria fish are attracted by this glowing light thinking it might be a small creature they can eat but by the time they realize they've been tricked it's too late Sea Devils don't therefore have to spend too much effort swimming large distances in search of food because the use of their lure means that food simply comes to them it doesn't matter what they attract either because they have such soft skin and stretchy stomachs that they are able to consume prey that's much larger than themselves number 10 the goblin shark of the more than 440 species of shark that are known to exist the goblin shark is one of the rarest and strangest that you'll ever see these creepy creatures live in the depths of the ocean around the world usually within trenches and on the side of continental slopes and due to their unusual body shapes aren't exactly the best swimmers growing to up to 20 feet long they have flat snouts that look like the blade of a dagger extending from the top of their head and have maneuverable jaws which means their long Barrow and incredibly sharp teeth can protrude as far forward as the tip of their snout when they're hunting they have long slender bodies which are covered in surprisingly flabby skin and have relatively small fins that mean it's unlikely they're able to swim fast enough to catch up with their main food source of fish and crustaceans instead they are believed to be ambush predators hiding in the shadows and waiting for a meal to swim past when the opportunity presents itself they thrust forward with a short burst of speed and snap with their jaws to incapacitate their prey number nine the deep-sea hatchetfish the deep-sea hatchet fish is a species that is found across the Pacific Atlantic and Indian Oceans but the chances of you ever seeing one are remote because they live far below where lights are able to penetrate when fully grown they can be anywhere between one and six inches long and are recognizable because of their peculiar body shapes that look like the structure of a hatchet to survive in the deep environment they've developed a clever system of bioluminescent cells across their entire bodies which can be used to camouflage in the water column to evade predators in a process known as counter illumination they're able to recreate the light intensity from above on the lower parts of their bodies that Bell is County rows of light producing cells called photophores so any predator that's beneath them and looking up won't be able to detect any shadows there are at least 40 different known species of hatchetfish many of which have shiny silvery scales slim bodies and blade-like dorsal fins that help them to swim through the water at much greater speeds than other similarly sized fish all of this combines to give them an advantage over their peers in a world where if you can hide and evade predators quicker than something else then your chances of survival are far greater number eight the zombie worm the rather ominously named zombie worm is a term given to more than 26 deep-sea worm species that are a vital part of the marine ecosystem and that many worms grow complex root systems like a tree if not majorly creepy at the same time the first were discovered quite recently in 2002 when they were found to be devouring the bones from the carcasses of a grey whale at a depth of almost 10,000 feet and since then they've been seen on most corpses that have come to rest at similar depths strangely they don't have mouths or stomachs and instead release acids from their skin that dissolve the fats within bones and then absorb the nutrients that they need to fully access everything that's available they actually drill into the bones with specialized roots and release plumes feather-like structures into the water that are used to filter oxygen for them to breathe if all of this isn't strange enough it's only the females that exhibit this behavior that's because the males are microscopic and actually permanently live inside the body of the female a recent sample found 111 males inside a single female worm which certainly aids to reduce the amount of time that's spent looking for a mate number seven the deep-sea dragon fish there is no doubt that the deep-sea dragon fish is one of the most frightening animals that live in the depths of the ocean and despite only growing - up to 12 inches long you most definitely wouldn't want to encounter one of these ferocious predators in their natural environment they have huge jaws that are filled with rows of some of the sharpest teeth of any animal living in the deepest depths they have to be able to take advantage of any food source they find even if it's much larger than them so they are able to open their jaws to an angle of more than 100 degrees which means they can consume other fish that are up to 50% larger than their own body in a similar way to other fish that live in the cold dark depths they have a barbell that hangs from their chins and contains bioluminescent bacteria this attracts unsuspecting fish who think they've spotted a potential meal for themselves and once they get close enough the dragon fish will snap with its vicious teeth they also have light producing cells along their bodies which are used to further disorient other fish and are also believed to be used for communicating with others of their species and to produce colorful displays to attract the mate number 6 probe shark often referred to as living fossils because the species hasn't changed much for millions of years frilled sharks are found between depths of three hundred and six thousand feet throughout the Pacific and Atlantic oceans typically growing to up to seven feet long they get their name because of the six frilly gill slits that to begin at the top of their throats this species is very rarely seen and so little is actually known about their behavior or range it has rows upon rows of Trident shaped teeth and fringe like gills they are thought to hunt and swim in a similar way to how snakes traverse through the water slithering side-to-side to propel themselves forward and then lunging towards prey before swallowing it whole they have flexible jaws that can open surprisingly wide and their mouths and throats are lined with countless rows of small teeth that are angled inwards and mean that once something has entered the mouth it has very little chance of escaping due to their strange eel-like appearance it's thought that frilled sharks could have been the inspiration behind ancient marine ER tales of sea serpents as they spend most of their lives at depth they are occasionally seen closer to the surface particularly at night in search of food number-5 Liopleurodon the oceans of the Late Jurassic period around 160 million years ago were a far more dangerous place than they are today and one of the biggest monsters of them all was the Liopleurodon growing to an estimated 21 feet long their name means smooth sided toothed because of their rounded sites this doesn't mean they lack a ferocious bite however because these teeth were three or four inches long and combined with a powerful jaw could have easily torn through flesh or shells they have four large limbs that they used to paddle themselves through the water and while this wouldn't have been able to sustain high speeds for long periods of time the Liopleurodon could easily accelerate for short bursts which would have been more than enough to capture virtually any prey that swam into its path it's thought that they would have laid in wait and had huge nostril that enabled them to smell for approaching sense and gave them plenty of warning to prepare to launch an assault on a target at the perfect moment number four giant spider crab the deeper a species lives the larger it's able to grow thanks to a phenomenon called deep-sea gigantism this results in some unbelievable freaks of nature such as the Japanese spider crab they live at depths of several thousand feet and have the largest leg span of any anthropods incredibly specimens can measure as much as 13 feet from claw to claw almost 3 metres long and weighed about 20 kilograms with a body that's 19 inches across they tend to live around vents on the sea floor and eat the plant life that thrives on the nutrients as well as small animals that arrive in search of food they have spikes all along their legs as an added layer of defense on top of their heavily armored shells and while they normally have eight legs it's not uncommon to find ones with fewer after having lost them to predators or human activity living to up to 100 years they frequently molt and form a new shell as their body grows and during this process they can replace virtually any body part that has gone missing this species is a highly sought-after delicacy in Japan but fishing them comes with its risks as they are twice the size of a person and have extremely powerful claws fishermen often report injuries that can range from scratches and deep cuts to severed fingers number three six Gill shark the blunt nose sixgill shark is a relatively abundant species that can be found into the depths of all the oceans on earth and are recognizable because they have six gills instead of the usual five usually growing to around 13 or 14 feet long but with some claimed to have been 18 or even 26 feet long they are one of the largest species of fish that feeds on prey that isn't plankton and exists on a diet made up mainly of fish raised and squid they are very similar to fossil that have been found from many millions of years ago 666 cows mythical I come for it come for it which would suggest that they are very effective at surviving where many other creatures struggle they aren't particularly fast in the water but are able to generate quick bursts of speed when they're hunting to catch up with and overwhelm their prey with their sharp teeth they are generally regarded as being harmless to humans because of their docile nature but if you were to ever provoke one they wouldn't think twice about striking back number two helicopter on the helicopter on was one of the most bizarre-looking species of shark that ever lived and roamed the ocean depths around 290 million years ago instead of having rows of teeth in their mouths they had what is known as a tooth whirl which would have grown to be at least 18 inches in diameter if the shark itself was more than 33 feet long with some evidence suggesting they may have been much larger than that meaning they would have undoubtedly been the apex predators wherever they went quite how they used the war'll for hunting and eating isn't exactly clear though because there's nothing quite like it nowadays to compare against it's theorized that they had no teeth on their upper jaw and that they would crush their prey between the war'll and the top of their mouth or perhaps use it in a sawing motion to tear away at flesh and scales we should be thankful that these creatures aren't around anymore because if they were the ocean wouldn't be a very safe place to be at all number one Mosasaurus living between 82 and 66 million years ago the most a source was one of the most vicious and dangerous ocean predators to ever have been in the oceans they grew to at least 52 feet long but with such tremendous bulk and muscle they could potentially have weighed as much as a blue whale surprisingly the closest living relatives to the Mosasaurus are snakes and this can probably tell us a lot about how they hunted [Applause] dwarf n'ver Chua Lee anything else that was alive at the time Mosasaurus was at the top of the food chain and would have seen everything as potential prey probably even simply swallowing at home for larger victims that put up more of a fight however it was equipted with rows of teeth that were the same size and sharpness as a dagger which would have made light work of even the toughest of protective shells they are generally regarded as one of the most deadly things to have ever swum the oceans and even though not as large as a fully grown Megalodon would certainly have put up a good fight against one if they had been alive at the same time which of these did you find to be the scariest and can you even believe that they exist make sure to let us know in the comments also check out our other cool stuff showing up on screen right now see you next time [Music]
