  • Several months ago

  • I created a video explaining the different sizes

  • of sea creatures that currently exist. While impressive

  • I didn't talk about the sizes of land creatures at all

  • Which will be the focus of this video

  • Standing 4m tall and weighing up to 6000kg

  • The African Elephant is the largest land animal

  • that currently exists. For scale

  • an average human stand 1.6m tall

  • and weighs 62kg, yet

  • the African elephant is considered a tiny creature

  • when compared to the titans that once

  • roamed the earth even though this first creature was smaller than the African Elephant, the Anthripornis

  • still looks unsettling when compared next to a human.

  • As the largest penguin known to ever exist,

  • the Anthripornis stood at 1.8m tall and

  • weighed 90kg. A large number

  • of other creatures that currently exist today had WAY

  • bigger and more terrifying ancestors that used to

  • live on our planet, for example, take any rodent

  • today and compare them to Josephartagsia monesi

  • an alarming creature which can grow up to

  • 3m in length, stand 1.5m

  • tall and weigh up to 1 ton

  • That is almost the weight of a full Toyota

  • Corolla in the form of what is essentially a

  • rat, yet arguably the most terrifiying

  • creature to have ever existed was the

  • A gigantic snake that lived millions

  • of years ago in modern South America, known to grow

  • up to 12.8m long and weigh up to

  • 1135kg

  • This snake can consume a human in just

  • ONE GULP, safe to say, I'm pretty glad that this thing

  • doesn't exist anymore. The largest arachnid to ever

  • exist was a creature called

  • A scorpion-like creature that could grow up to

  • 70cm LONG!! Yeah,

  • A pack of this things would not be a very welcome sight.

  • But a single Sarcosucnus would be equally as

  • terrifying. This creature was the largest

  • crocodile to have ever existed. Known to have grown

  • up to 12m in length and weigh a ridiculous

  • 8 TONS!!! It would take more than

  • 6 Toyota Corolla to depict it's

  • mass. Though frightening, this beast is far

  • from the largest Carnivore to have ever existed.

  • The T.Rex often comes to mind when we think of

  • history's largest Carnivore.

  • But this title really belongs to the

  • Measuring a terrifying 15m long and

  • weighing up to 21t

  • Paleontologist John R. Horner remarked

  • So while the Spinosaurus holds the record

  • for being the largest Carnivore, it is not the largest

  • land creature in history. That distinction has to go

  • To the aptly named

  • Measurements taken from a confirmed specimen revealed

  • that at least one of these creatures grew to an impressive

  • length of 37m and weighed

  • 69 TONS!!! Which is the equivalent of about

  • 12 fully grown African Elephants!!!

  • Compared to a human, the size of this ancient creature

  • truly epic!!! Which has lead scientists to

  • estimate that the Titanosaur grew to the

  • maximum size that biology will allow

  • land creatures to get to on earth!!! For instance,

  • if you take any creature on earth and increased it's size

  • somehow, it's mass would increase by a power

  • of 3. The width of the creature body meaning its muscles

  • and bones, would only increase by a power of 2.

  • Therefore, the larger the creature is,

  • the more mass needs to be dedicated to bones

  • in order to support it. Because of this law,

  • and the effective gravity on earth, it is extremely

  • unlikely that a land creature has ever existed

  • that weighed over 100 tons

  • Meanwhile, the ocean plays by a different

  • set of rules. The impact on size that gravity has

  • on the earth's surface is not affected in the ocean by

  • Buoyancy. So, unlike their counterparts on land,

  • creatures in the ocean don't have to prop up

  • all of their own weight. Which is how you end up with a colossus

  • like the Blue Whale

  • At 181 TONS!!!

  • The largest creature known to have ever existed.

  • But even this titan is likely

  • approaching the largest possible size of an Ocean

  • Creature. The problem is no longer Gravity, but

  • food and energy consumption.

  • The Blue Whale has to consume 3600kg

  • of Krill every single day just to meet

  • it's daily calorie needs. That's the same as about

  • 16700 Big Macs!!!

  • For just 1 whale. Anything larger

  • would have to consume even more food. And the

  • the larger it gets, more difficult it becomes to find that food.
