Ever wanted to take a dive into the deepest
parts of the ocean? Well, today you’re gonna have this opportunity! Now, how good are you at holding your breath? Not that good? Well not to worry. Hop on board of my submersible craft and join
me in the voyage to the depths! Ready? Let’s dive! Right now, just below the surface, you see
that life is thriving here. Fish and marine animals abound, and — hey
there! — swimmers are waving at us. But we won’t be staying here for long. Buh-bye! At 65 ft, there’s a whole new world opening
before your eyes: shallow coral reefs are standing beautifully not far from the shore. And hey, there are people here again! It’s scuba divers this time, though. Water pressure isn’t kind to divers without
special equipment. 130 ft is the depth where we say goodbye even
to recreational scuba divers — it’s the maximum allowed for them. Take care, guys! 200 ft — and here’s the first orca! These whales inhabit the relatively shallow
waters of almost every sea and ocean in the world. Did you know they’re the apex predators,
by the way? It means they have no natural enemies and
no one can take them down. At 230 ft we meet whale sharks — the largest
known fish species, weighing up to 60 tons. And they’re also quite long-livers: well
yeah I guess their livers are long at that, but actually it’s about their life expectancy:
they can live about 130 years. Now look outside: if you see a scuba diver,
it’s a real pro, because at 330 ft they’ll have to be very cautious not to get decompression
sickness. It occurs if you rise too quickly to the surface. And if you’re lucky, you can also see a
giant Pacific octopus — it dwells in cool waters starting this deep and going down as
far as 6,600 ft. And now we’re entering the dark part of
the ocean: at 490 ft, just 1% of the light from the surface reaches us. All the rest is absorbed by water. Everything that’s deeper will get darker
and darker still. Oh, look! At 660 ft, there’s a giant oarfish circling
our submersible. These creatures are believed to be the source
of all sea serpent sightings, and a lot of alliteration! Sometimes they swim up to the surface and
freak out sailors and swimmers. No wonder: these fish can reach 36 ft in length
— enough to scare the heck out of me, for example. Okay, now we’re at 980 ft and… wait, what’s
that huge and gangling thing out there? Oh, I get it, it’s a Japanese spider crab! Why a spider, you ask? Well, just look at those legs and the answer
will come to you without further prompts. By the way, there’s almost nothing more
to them than legs: the body of such a crab is normally just 1.5 ft across. Going deeper now, and at 1,640 ft you’re
going to see the last of the blue whales — no, not really the last of them, I mean, that’s
the deepest they can swim. They don’t really need to dive that deep
for food, which they have in abundance in shallower waters, but they still can. I guess it’s just for the sake of showing
how awesome they are. After all, they’re the largest creatures
in the history of Earth — both in the sea and on land! Shh… You hear this? These are the sounds fin whales are making
to talk to their friends many miles away. They can do this thanks to the SOFAR channel,
or Deep Sea Channel, that generally starts at 1,970 ft, but can vary in depth. It’s a layer of water where the speed of
sound is at its minimum, and sound waves can go thousands of miles before disappearing. At the depth of 2,723 ft we have reached the
point where the Burj Khalifa, the tallest building in the world, would not even show
its tip on the surface if it were put underwater. Hey let’s try that! Now we’re entering the really interesting
part of the ocean, where no sunlight reaches us, and strange creatures dwell. One of those is the giant squid — yes, that
legendary type. It inhabits the depths of 2,950 ft. Just imagine the creature with eyes the size
of frisbees! Sperm whales hunt down these beasts, but they
certainly can fight back. What a sight it would be to see such an encounter! And that’s where pitch darkness finally
falls on us. The Midnight Zone. The pressure here is so huge that, if you
somehow end up being here without a submersible, you’ll simply be crushed in a couple of
seconds. And that without seeing a thing too. Not the best of prospects. Anyway, at 3,600 ft, there’s West Mata — one
of the deepest ocean volcanoes in the world. Its last eruption was in 2009, and it was
even filmed by a remotely operated vehicle! 4,200 ft down below, and we see the ferocious
great white sharks — these ultimate predators feel great at such a depth. Their eyesight is rather poor, and they navigate
by scent, so they don’t really need sunlight to hunt down their prey. “I don’t see you, but I’ll still eat
you.” Brr. Also, the leatherback turtles, the largest
turtles in the world, dive at the same depth. I wonder if they do it to tease the great
whites? See those huge nets? That’s because we’re now at the depth
of 4,900 ft where the “catch-all” fishing method is used. The nets are here to be dragged along the
ocean floor, catching everything unfortunate enough to be caught. I’ll let you decide how detrimental this
is to the ocean life here. At 6,000 ft, if we were in the Grand Canyon,
we’d be sitting at its lowest and deepest point. Imagine that all of its crevasses have been
thoroughly filled with water, and you’ll get the perfect picture. Now, if we’re really careful, then at the
depth of 6,600 ft, we’ll be able to see the black dragonfish — a nightmarish creature
that dwells in the deep and dark parts of the ocean. And trust me, it’s better off staying right
there! It looks like something from a horror movie,
and I’d rather it never crossed my path. At 7,400 ft we’ll be saying goodbye to sperm
whales — this is the deepest point they can dive, and frankly, they have no real business
at such a depth. Maybe they hunt the black dragonfish, of course,
or… it hunts them? Nah, the difference in size is too big: sperm
whales can reach 62 ft in length, which makes them the largest toothed whales in the world. Not many creatures can counter that. It’s good that our submersible has a powerful
floodlight — without it, we wouldn’t have been able to see the astonishing beauty of
the deep-sea coral reefs located at the depth of 9,900 ft. They can be found in every ocean, and it’s
a pity they can’t be seen without special deep-sea diving equipment. Okay, going deeper still, and at 12,100 ft
we reach the average depth of the World Ocean. From now on, the journey into the real depths
begins — the general ocean floor has been passed, so now it’s time to delve into the
Abyss. I won’t tell you not to be afraid because
the scariest creatures of the deep dwell here, below the Midnight Zone. And it doesn’t end there: the pressure on
the upper limit of the Abyss, at 13,100 ft, is like a whole regiment of elephants stomping
on you. Not that you’d have the time to feel it,
though. At 15,000 ft, the monsters out of your worst
nightmares pop up. Anglerfish, for example, will scare the heck
out of anyone — its long and crooked teeth along with a growth on its head that lures
the prey are enough to instill fear even in the bravest. But perhaps even more terrible is the creature
called the black swallower. It’s an eel-like beast that has a very stretchy
stomach, and it can swallow prey that’s twice its size! I don’t know about you, but I’d rather
switch off the lights not to see anything this deep in the ocean. What? You want to see it all? ….Alright, if you insist… Look down below and you’re gonna see the
deepest shipwreck ever found: SS Rio Grande in the South Atlantic sunk in 1941 and went
as low as 18,900 ft. No wonder it was only found 55 years later! And now the deepest and darkest part of the
ocean begins: we’re diving into the Mariana trench. Officially, it begins at about 19,700 ft deep. It’s both the least explored and the most
fascinating area for the scientists and adventurers alike. What lies at the bottom of it? Well, we’re about to see, but while we’re
not yet there, I’ll show you something else. For example, here’s the deepest fish ever
found: it’s called a snailfish, and it dwells at 26,000 ft. Its body is translucent, so you can actually
see right through its skin. Well, I must say I’m glad we didn’t turn
off the lights, after all — this little guy is surprisingly cute for a creature that
can withstand such pressure. Going lower and deeper, you won’t see any
other kind of fish or vertebrate animal whatsoever — the pressure is just too much for such
creatures. But there are shrimps and other invertebrates
— not to mention microbes — that can dwell even in the deepest part of the ocean. And that part is the Challenger Deep. It’s the bottom of the Mariana trench, and
its depth is 35,853 ft. Yes, we’ve arrived at the very bottom of
the Earth. Few people have been here, and very little
is known about it yet. But scientists aren’t going to stop, and
there’s hope we’ll soon find out what secrets the depths of the ocean hold. How about you? Would you dare explore the ocean on your own,
if you had a chance? Let me know down in the comments! Hey, if you learned something new today, then
give this video a like and share it with a friend. But don’t go deep diving just yet! We have over 2,000 cool videos for you to

what is the phobia of long videos lol
Friggin terrifying :(
