What lives on the bottom of the Mariana Trench? the memory on a trench is a crescent-shaped trench in the western Pacific just east of the Mariana Islands near Guam, the trench contains the deepest known points on earth vents the bubbling of liquid sulfur and carbon dioxide as well as active mud volcanoes and marine life that adapted to pressures a thousand times that at sea level but just how deep is the deepest part of the ocean the Challenger Deep
which is the deepest part of the trench also making it officially the deepest part of the ocean was packed at 36,000 and seventy feet and was measured using the sound pulse is sent through the ocean from the surface and was conducted back in 2010 by the National Oceanic and Atmospheric Administration or the NOAA What lives on the bottom of the Mariana Trench?
it was initially believed that the bottom of the Mariana Trench was a vast lifeless wasteland the Greek philosopher Socrates Luke 24 hundred years ago apparently said everything is corroded by the brine and there is no vegetation worth mentioning and scarcely any degree of perfect formation but only caverns and sand at measureless mud and tracks of slime in the Victorian era this idea was championed by a scientist called Edward Forbes,
he dredged the Aegean Sea and founded the deeper he looked the fewer organisms he discovered he concluded that life ceased to exist beyond 18,000 feet, of course, these statements have long been disproven by science life however sparse exists down there and the creatures living there are some of the weirdest creatures ever to have been discovered by science they have evolved in such a way to make do of what the environment offers them long intro assigns a day What lives on the bottom of the Mariana Trench?
we will be answering the question of what actually lives the bottom of the Mariana Trench let’s not waste any more time and with all that said and done let’s begin shall we fish with flashlights it’s literally pitch-black down there in ideal conditions sunlight may reach 3,280 feet below sea level but usually peers out of it around 656 feet given that fact animals living down in the trench only have two choices either evolved to not be dependent on light or produced their own light bioluminescence is the ability of creatures
who produce their own light use either for hunting or attracting a mate many creatures living in the church have this ability to various degrees of intensity hatchet fish, for instance, have bioluminescent bodies they can even alter the brightness of their glow depending on how much light is filtering from above in doing so they’re counter illuminating their bodies in a clever camouflage technique What lives on the bottom of the Mariana Trench?
What lives on the bottom of the Mariana Trench?
their dim self-produced light reduces their silhouettes making it much more difficult for predators to spot them from below dragonfish also a resident of the deep also relies heavily on bioluminescent body parts which leverage internal chemical reactions to produce an eerie glow the fish may use this glow to communicate with other fish or to provide camouflage it also Dingles a lighted barbie or whisker-like protrusion from its lower jaw other fish are attracted to the barbel mistaking it for an easy meal but in a flash, the dragonfish gets lunch instead of some dragonfish also evolved
the ability to produce a red glow and the unusual colour of light for ocean dwellers, they may use their reddish hue to signal their brethren but it’s more likely that they’re using the red lamp to illuminate prey just before launching an attack and lastly, we go to probably the most famous inhabitant of the trench What lives on the bottom of the Mariana Trench?
the angler fish there are about 3,200 speeches of angler fish 160 of them are deep water species they are often called the fishermen of the deep sea mainly because of a certain part of their Anatomy and how they use it to catch prey it has a protrusion from its a forehead that dangles a glowing lure to attract starstruck luckless animals with its huge gaping jaws the angler fish can actually devour creatures much larger than itself before we move on I’ve got a little challenge for you tha

if you’ve ever seen the iconic movie aliens, you’ve been haunted by dreams of toothy bald creatures bursting from your chests and snapping at your face now picture a shark was just such a face swimming around in the darkest deepest seas that would be the goblin shark an aptly named monstrosity from your worst nightmares goblin sharks have a protruding snout that looks like the pointy sword just below the snout is a said their protruding jaws that appear to be mismatched with a shark’s face
as if evolution spun the wheel of ugly and the goblin shark lost in the worst possible way what’s more these sharks aren’t your stereotypical grey colour and said their skin as a distinct pinkish hue then we have their cousin at the frilled shark frilled sharks with dog a mix-and-match special from the discount the aisle at your local evolution convenience store they have the rounded body of an eel paired with a flattened What lives on the bottom of the Mariana Trench?
the head that would likely be right at home atop a terrestrial dinosaur perhaps that’s fitting though because like many sharks this species has ancient roots that extend back nearly 80 million years the shark derives its name from six rows of frilly gills that grace its body which grows up to six feet long does is notably,
the shark wields more than twenty rows of wicked trident shaped teeth that will tear into any bit of flesh that passes near them for years many people assume that filled shark swam and hunted like eels some readers think an awkward arrangement of internal organs would make that kind of movement in instead, What lives on the bottom of the Mariana Trench?
they say these sharks may actually strike their prey with the action of a land-based snake making them even weirder single-celled Giants single-celled organisms are a tiny well usually tiny in the Mariana Trench however tiny is not going to cut it for these single-celled animals called Zenobia for as they refer to scribed in the 1970s originally thought to be sponges
they were later identified as single gigantic cells and classified as members of the kingdom Protista along with other single-celled organisms and simple multicellular life lacking specialized tissues genetic studies have identified the Zenobia for is a type of a form on a ferret a group of amoeba that usually have shells or tests formed from calcium carbonate the minuscule fossils of which are the major constituent of limestone unlike another form an affair, however, Zenobia fours do not have calcium carbonate tests What lives on the bottom of the Mariana Trench?
this is because of the extreme deep-sea pressures at which they live which is more than 1,000 times atmospheric pressure at sea level any hard calcium carbonate shell would only liquefy instead, Xena fibres have transparent tests made from an organic glue mist with particles of clay minerals the skeletal remains of other organisms and other substances picked up as they move along the ocean floor it’s their name which
when translated from Greek means bearer of foreign bodies they are often more than ten centimetres in diameter and individuals of the largest species aptly named siren gam Mina Fraggle Asaba has been found that are twice this size in contrast other Foreman of Ferren’s are commonly less than one millimetre across different speeches of Zenith Ioffe or vary widely in their appearance ranging from flattened disc spheres and from angular to free the individuals of one species to exist as a series of branching tubes embedded beneath the ocean floor like many deep-sea animals inna five fours are well What lives on the bottom of the Mariana Trench?
This is the life of What lives on the bottom of the Mariana Trench?
adapted to the extreme cold and high-pressure of ocean trench life but are fragile and difficult to bring back to the surface for closer study as a consequence little is known about their reproduction and other behaviours they are however very abundant in their natural habitat in some regions of the ocean floor as many as 2000 Zina five fours have been counted hundred square meters armour-plated shrimp well not exactly shrimp a rather a distant relative amphipods are small shrimp-like crustaceans that can be found in most aquatic ecosystems
the thing is they aren’t really known as deep-sea dwellers while it’s true that some hearty specimens have been found in the relatively deep ocean they’re hard exoskeleton starts to deteriorate when they dive below 15,000 feet they’re a combination of crushing pressures low temperature and higher acidity causes the calcium carbonate in their exoskeletons to dissolve making them vulnerable to the pressure and predators that’s why
it’s a prize scientist a discovery species of amphipod in the Challenger Deep and the reason why they can survive there is something written straight out of medieval storybooks Hiren Delia gigas or H gigas for short is the only own amphipod able to survive the 15,000 feet threshold scientists found that this extreme amphipod constructs a personal suit of armour a layer of aluminium hydroxide gel covering the surface of its exoskeleton but aluminium isn’t abundant in ocean water making it hard to source as a building material is however abundant in ocean sediment to figure out What lives on the bottom of the Mariana Trench?
how h gigas accesses it’s aluminium the team exposed sediment from the Challenger Deep which the crustacean likely swallows when eating two chemicals in its gut within that acidic environment a bright product of the plants in its typical diet reacts with the metal-rich sediment to free up aluminium ions when these aluminium ions are released into alkaline water they transform into a protective aluminium hydroxide jet look to put it simply
they eat aluminium they poop out a Lumina my aunt which then mixes with water and then they turn it into armour so in order to survive they wear a heavy metal poop armour it’s probably not like that at all but I’m no scientist and that’s as far as I understand it in any case as aluminium armour appears to both relieve stress from deep-sea pressures and prevent the amphipod exoskeletons from leaching calcium carbonate and disintegrating things in these findings scientists are one step closer to understanding What lives on the bottom of the Mariana Trench?
how it is possible to survive in one of the world’s harshest environments finally, a whole lot of slime if you’re like a lot of people you’ll love the sensation of wet sand under your feet you think that the entire ocean would be covered with it but you thought wrong if you happen to keep swimming deeper and deeper and deeper all the way down to the depth of the trench the ground would suddenly feel very very different that’s because thanks to everything that trickles down from the miles above everything in the trench is covered in a blanket of icky viscous lbs sand as we know it doesn’t really exist down there in its places well something that What lives on the bottom of the Mariana Trench?
I could only describe is the remnants of death and decay the floor of the trench is comprised mainly of crushed shells in the courses of plankton that have sunk to the bottom over the years due to the immense water pressure everything pretty much ends up ground into a fine greyish-yellow almost silky sludge considering how long the trench has been around being considered by many scientists as the oldest part of the ocean one can only wonder how deep the use forgoes down before earth actually begins despite being a slimy mess life still finds a way to exists out there that part of the ocean floor is home to a very peculiar animal officially it’s called the ascetics and
its name, as well as its feathery appearance, make it seem like a plan from a dr. Seuss book but this worm also goes by fiercer monikers such as the bone worm or zombie work and it can consume the wrong card bones of some of Earth’s biggest animals this includes whales the zombie worm secretes acids to help it access the inner content of those dead whale bones then it uses symbiotic bacteria to convert the bones proteins and fats into nutrients that serve as its food its feathery branches wiggle in the water pulling in oxygen to keep What lives on the bottom of the Mariana Trench?
