If I were to ask you what’s the largest thing
to have ever lived on planet earth, most people would say… THE BLUE WHALE OF COURSE! But,
despite popular belief… it’s not! So, what on earth… is or should I say was? I’m Stu, this is Debunked, and we’re here
to sort the truth from the myths and the facts from the misconceptions. Okay, so if the Blue Whale sets the benchmark
by which all other living creatures are measured, it probably makes sense to first establish
just how BIG a Blue Whale can get? The biggest one ever discovered was found
in the Southern Ocean of Antarctica back in 1947. it weighed in at a hefty 190 metric
tons (209.4 US TONS / 418,878 lb), which is the equivalent to 104 standard family
SUVs. It also measured a huge 27.6 meters (90 ft 6 in) long, close to the length of
a short haul airliner (Airbus 318) and its estimated volume was roughly the size
of 7 fuel trucks, at 223 cubic meters (7875 feet3). Remember that for later… What could possibly out-size something this
massive? Well, whales first appeared around 40 million
years ago, so to find out what could possibly top such a titan, it would make sense to take a look at this
prehistoric era of Earth’s history, when great monstrous-sized beasts walked the
planet, plants were the size of VWs and colossal creatures
swam in our oceans. So, let’s start with dinosaurs… or more
accurately Titanosaurs – a group of four legged veggiesaurus’ with
long tails and small heads. The largest of these dinosaurs to have ever
walked the Earth is believed to be the Argentinosaurus. Its discovery in the 1990s stunned paleontologists
the world over, with a length of 35 meters and a weight of
70 metric tons (tonnes / 70,000kg)! Put this next to most people’s common point
of dino sized reference – the T-Rex, and it dwarfs the goat eating carnivore. However the title was hotly contended in 2017
by the discovery of the Patagotitan mayorum. This titanosaur was believed to have a skeleton
10% larger than the Argentinosaurus, but recent weight estimations put it just
shy at 69 tonnes. Both Titanosaurs maybe longer than the whale,
but put the Argentinosaurus and the Patagotitan on a set of scales and
the pair together wouldn’t out weigh our big blue heffer. —- In fact, Whales are so much larger because
they live in the ocean. On land, animals suffer the full effect of
gravity, but for sea based organisms; the water’s buoyancy reduces the strain
on their muscles and skeletons, allowing them to grow to such vast sizes. When something as huge as a blue whale becomes
beached or stranded on land, their muscles can’t support their body weight
out the water and they will basically be crushed to death under their own weight. So with the ocean providing the best environment
for a creature to super-size itself, let’s take a look in to the deep blue, and
more specifically the Cretaceous period to see what competition there would have been… Now anyone who’s witnessed this scene before
will surely think that this prehistoric monster offers some competition for a Blue Whale? That, is a Mosasaur… and THAT is a GREAT WHITE SHARK serving as
an amuse bouche. Now, if this is your average sized Great White
then the Mosasaur would make up the length of about 9 of these sharks. With your average Great White measuring in
at 5.3 meters, that means the Mosasaur measures in at nearly 48 METERS! And this is how our Blue Whale sizes up against
this leviathan! But here’s where Hollywood gets carried away
with itself… Mosasaurs aren’t believed to have grown
any longer than 18 meters, with the largest one to have been excavated
sitting at a modest 15 meters, meaning Jurassic World’s reptile is grotesquely
inaccurate. Anyway that’s enough science fiction, let’s
get back to the science fact. What is the largest creature to have ever
swam in our oceans?, Fortunately, a discovery in 2018 may have the answer. Measuring in at nearly 26 meters, that’s
only just short of our largest blue whale, it’s believed that this giant Ichthyosaur
may have been the largest aquatic reptile ever! However, with its dolphin-like shape, a long
pointy jaw and streamlined body, it’s estimated weight falls far below that of the Whale, meaning the Blue Whale still stands as the
largest animal to have ever swam in our planet’s waters. Let’s leave the wet stuff behind now and
head back to land, where the competition to be crowned largest
living thing is starting to hot up. What stands taller than the largest dinosaurs
and doesn’t suffer the effect of gravity like other living, breathing organisms? The trees… As we travel to the coast of California, we’ll
find the Redwoods National Park, and here you’ll see, Hyperion! Even fantasy doesn’t top this living behemoth,
take a recent incarnation of Godzilla and put it next to the Sequoia, and it stands around 10% taller at a staggering
115.85 meters! And if Godzilla’s not your thing then take
a look at how the Statue Of Liberty sizes up! Yet, height isn’t everything, we’re after
the largest and that doesn’t necessarily mean the tallest, so for that we need to travel
down the coast to meet General Sherman, a 2,100 year old Giant Sequoia. He may stand
at a humble 82.6 meters (271 ft) tall by comparison, but has a whopping volume of 1,487 cubic meters
(52,513 cubic feet), blowing old Bluey out of the water! Because
in fact you could squeeze around 7 blue whales inside this tree. When the General’s root system is taken
in to account it’s believed that this single organism would weigh 1,814 tonnes (4,000,000
lb)! And, as astounding as those stats are, there
was once a tree larger than the General , measuring 1,727 cubic meters, but it was
sadly cut down in the 1940s. However, even with these giants of the forest, believe it or not we’ve still not found
the largest thing to have ever lived on our planet… To find what we’re looking for, we need
to travel to the Blue Mountains Of Eastern Oregon, and here you won’t find the largest living
organism towering over the forest, swimming through the lakes or stomping around
the mountains. Instead, we need to look below our feet. Under
the forest floor of the Malheur National Forest, you’ll find something that you may not have
expected to come out on top in this video. While we’ve been looking at all the relevant
Kingdoms of Life on planet earth, there’s one we’re forgetting… Fungi
(Fun-gee), OR Fungi (Fun-guy) or Fungi (Fun-jei), depending on where you’re from! Here, on the ground, we find the Armillaria
ostoyae, or more commonly known as the Honey Fungus. All that we generally see is the fruiting
body, what we would consider a mushroom or toadstool. But this is often only 10% of a fungus, the
rest of the organism, the vegetative part, is below the earth. To make this concept more familiar, imagine
this as a fruit tree, and you’d see the leaves, branches and stems all below ground with only
the fruit appearing above. This fungus however is no ally to trees. The
Honey Fungus is actually devouring the forest from the ground up. Now most people won’t think of fungi as
tree killers, as they are in fact a cornerstone to the entire
ecosystem of a forest, usually breaking down organic debris like
fallen leaves and transferring essential minerals to the plants. Here, however, the Armillaria ostoyae has
a much more parasitic purpose. It attaches itself to the forest’s conifer
trees and begins to feed off of their roots, killing the tree in the process. Nicknamed the Humongous Fungus, the wealth
of trees in this area has enabled it to spread far and wide, and currently this fungi stretches across
2,200 acres or 8.9 square kilometers (3.4 square miles) below the soil! To put what you are seeing here in to perspective,
that is the equivalent… of around 1,700 NFL football fields, or 36,500
tennis courts. Now, the discovery of the Humongous Fungus
sparked debate as to what constitutes a ‘single living organism’. But it can be succinctly summed up by Biology
Professor Tom Volk… Which is exactly what the Honey Fungus is,
meaning this is indeed a single living organism, just like the Giant Sequoia or the Blue Whale. And it’s not just the extensive area it
covers that makes the Armillaria ostoyae so huge, it’s discoverer James B. Anderson from the
University of Toronto recently surveyed the site, and now estimates that if the entire fungus were dug up out
of the ground and weighed, it would top the scales at 400 tonnes, more
than double the heft of a Blue Whale! But, as with anything at this scale, it brings
with it some controversy. There is another single organism spread over
a vast area that is touting for the same title of Largest Living Organism. Head down to Utah and you’ll find this huge
tree… …nope back out a little… there. This,
is one, tree. Known as the ‘Trembling Giant’ OR ‘Pando’
(Latin for “I, Spread.”) this entire grove of 47,000 Quaking Aspen
trees has grown from a single root system. You see, Aspens find most success in regenerating
‘vegetatively’, meaning sprouting from roots (not from seedlings),
this results in what’s termed a ‘clone’. Just like the Honey Fungus, this forest is
genetically identical and it behaves as one organism. With the changing seasons, the whole forest
changes color and sheds all its leaves in unison. And, most fascinatingly, as an old tree dies
in the clonal grove, signals are sent from the tree out to the network of roots, which then stimulate new growth for the next
generation to replace the old. Now this colony may look substantially more
impressive than the humble honey Fungus, but… we’re only looking at 106 acres. Less than 5%, of the area covered by the Fungus. So surely there’s no competition? Well,
the complications come when weight is included in the criteria. As we’ve learnt the Humongous Fungus weighs
in at 400 tonnes, where as it’s estimated that Pando smashes through that record weighing
a colossal six… thousand tonnes! In fact the ‘United States Department Of
Agriculture’ list the both Pando and the Humongous Fungus as the ‘Largest Organism
On Earth’ So, surely the only way that this can be settled
is to confirm it with the great holders of such titles, over at the Guinness World Records. Well no, the record for ‘Largest Living
Organism’ seems so controversial that even Guiness haven’t yet declared it. According to their records, Pando is confirmed
as the ‘Most Massive Plant’ while the Honey Fungus holds the record for
‘Largest Fungi’. The most common criteria, however, that declares
anything as ‘Largest’ is specified under ‘Area Covered’. And under this, the Humungus Honey Fungus
is the outright winner. Even if you took into account the total estimated
volume of the two contenders then the Armillaria Ostoyae decimates the
Quaking Aspen at more than double its size. Pando is however, believed to hold the slightly
less grandiose record for ‘Largest Known Organism On Earth In Terms
Of Dry-Weight Mass’ as fungi are around 92% water. (Trees=50%
Water) On the other hand, the Humongous Fungus has
increased in size with subsequent surveys, where as, sad but true, Pando is dying. It has substantially reduced over the past
70 years due to human interference. And, it’s thought that within the next 10
to 20 years, up to 80% of the entire grove could collapse. Dr Paul Rogers, an Ecologist who recently
led a conservation effort to protect Pando, has said…

100 thoughts on “What’s The Largest Thing To Ever Live On Earth? DEBUNKED

  1. can sombody tell me the biggest thing is it has not to be alive ( comment down below ) i already know it but do you??

  2. it's pretty funny that so many peoples knowledge of giant ancient sea creatures is just…..Megalodon. Starts and Ends at Megalodon

    and any video about giant animals is gonna have a bunch of people shouting Megalodon in the comment section

  3. Dont mean to brag but I already knew the fungus was largest living thing on earth… think I saw that in an "Eyewitness" science video in like middle school or some thing

  4. I'm having hard time watching this because the music too loud compared to the voice. So I turn it up but then the music turns up as well. Makes it tedious to make out what he's saying.

  5. Clickbait fuckers. You guys were just trying to be smartasses, you know that your title would make people assume an animal, not some fucking plants.

    Was going to subscribe but decided not to.

  6. It's a blue whale has the fungi and tree are not a "signal" organisms. Cut a blue whale in half both parts will die has neither half can survive this is not the case for the fungi or trees which cut be cut not just in half but 100's of time and all those parts cut survive independently of each other. Take a cutting from either plant it on the other side of the Earth, is it now the size of the Earth, no it two different plants. Cut the whale in half and all you have is to piles of whale blubber!?

  7. Southern ocean of antarctica. But it's NORTH of antarctica.
    I dunno what to believe anymore…
    Holy fuck. Watch that stoned ape theory JRE episode to learn more about the climax of this video, than this vid could ever hope to offer.

  8. Once you state weight in kilograms & length in meters, will you PLEASE STOP STATING THEM IN FOOTBALL FIELDS & TENNIS COURTS?!!

  9. I asked google and it said that the megalodon were the largest PREDATOR to ever live in the ocean as I thought. However, female blue whales are on average 82ft and megalodons are usually 60ft so they are a tad smaller. I still have respect for the megalodon though because people call it the monster of the ocean it also ate humpback whales and other large fish.

  10. I know one of the biggest sea creatures that used to live……a Megalodon, if you don’t know what that is look it up

  11. Wait, counting all instances of a fungus in one region as one organism is like counting all humans in one city as one single person. It makes no sense.

  12. I call a bully on my road a whale and she is fat not gonna lie so if she is a whale then how is she still alive with her weight lol

  13. But…. how do we know dinosaurs even exist….. I mean…..museums don’t have real dinosaurs bones (i did research) and there is no public place to see real dinosaurs bones

    Smart I say 🙄

  14. For those interested, the longest animal on earth is actually a bootlace worm which washed up on the coasts of Scotland in 1864, the individual measuring in at a huge 55m.

  15. honestly what the fuck is the point of this video?? like it keeps showing us different animals and shit and still saying “iTs NoT lArGeR” fuck off

  16. I forgot about the fact that there is a fungus that is the largest organism in the world until about the middle of the video. After I remembered that the video became obsolete…

  17. What about that giant fungus that lives out west, that is supposed to be the size of a metropolitan city, that lives underground?

  18. I mean it doesn't look like the entire grove of panda even changed from 1939 to 2011 so its kind of hard to believe that 80% of the entire plant will be gone in 20 years.

  19. man, i wish i had never seen this guy. in my mind he was a stuffy old guy with a grey goatee and a tweed suit. it's almost as bad as hearing bukowski read his own work after having read most of his books.

  20. The largest recorded weight for the blue whale is not 190 metric tonnes, but 190 short tons (US tons), that is 173 metric tonnes. And the largest scientifically verified length is 29.9 metres – this animal wasn't weighed, though. http://www.sararegistry.gc.ca/virtual_sara/files/cosewic/sr_blue_whale_e.pdf

  21. I was never taught that they were the largest THING, they were the largest ANIMAL. Huge difference. In fact, at the same time we were taught about the blue whale, we were also taught about the redwood trees. Not the fungus though, because it wasn't known, or widely known at that time.
    This is in the early 80s in elementary school. So what you're saying is that schooling has gotten worse and lazier?
