Ok, that fish is giving me a strange look.
Macropinna have a wandering eye.
That means they can rotate their eyes all the way up
and look out of their transparent head.
"I don't like that ****."
Macropinna's eyes allow them to capture as much light
as possible.
When living in the ocean's extreme depths,
you need all the light you can get.
But macropinna aren’t the only species who call
impossibly deep waters home.
The Mariana Trench is 10,668 m (35,000 ft),
an ocean abyss that is the furthest down you can go
on Earth.
For now, we're going to start with the dumbo octopus.
Besides, I think they’re more cute than creepy.
They use their ear-like fins to propel them through the water
and their tentacles help them steer.
These octopuses don’t mind cooler water
and can even camouflage.
They change from soft pink to dark brown
or red when threatened.
A darker hue helps them blend in and stay safe in open water.
They’re cute but smart, that’s for sure.
"Come on, mama will hold you."
"Sweetest little thing!"
"They are just a bunch
of pansies!"
Far from cute is the frilled shark.
They may be hard on the eyes, but their bodies are
perfectly calibrated for deep-sea living.
Frilled sharks have large livers that
contain low-density fats to keep them afloat.
Being a shark and having sharp teeth
might seem like they go hand in hand.
But the deep-sea dragonfish rivals the bite of
all creatures in the ocean.
Their thin, jagged teeth
are stronger than both the great white shark
and piranha.
And they are one of the only animals on Earth
that can generate and see red light.
Most ocean dwellers produce blue light
and have evolved their camouflage abilities
to absorb blue light as well.
But the sneaky dragonfish's red light reflects off of prey,
making them easy to spot.
And then eat.
"Yeah."
"This is big brain time."
When you live in the Mariana Trench like the comb jelly,
light tricks are needed to survive.
They're more than 95% water and have no bones.
These jellies vibe through the water
and as light reflects through their bodies,
they produce a beautiful rainbow effect
through their clear skin.
Marine hatchetfish also uses light to adapt,
but their tricks keep them hidden.
Their reflective scales and light-emitting organs
called photophores offset their shadows in the water.
This is called counterillumination
and it keeps hatchetfish invisible to predators.
Osedax, who are also aptly called zombie worms,
live on the ocean floor and feed exclusively
on bones.
They've hit the jackpot when they come across whale bones.
It’s enough food to keep them sustained for a long time.
"You lucky son of a *****."
Unlike Osedax, most creatures have to hunt for their food.
And no one does it quite like the anglerfish.
Their long, rod-like appendage lures
prey right under their nose.
Then the anglerfish snaps them up.
It’s a fish-eat-fish world out there.
"You've gotta be quicker than that."
Our honorable mention goes to the prehistoric megalodon.
This is the largest shark to have ever lived,
and yes, some people think it might lurk
in the Mariana Trench, out of sight.
But scientists have widely discredited this theory.
There’s not enough food to keep these monsters fed.
One shark that is definitely down there
is the goblin shark.
And they’ve been around for a long time.
Around 125 million years.
They are not known for their speed.
Even a sea turtle could outswim them.
But they are known for their bite.
These sharks can extend their jaw 30 cm (1 ft) past their body
and have incredibly sharp teeth.
Which deep sea creature was your favorite?
I find the dumbo octopus very cute.
And as it just so happens,
we have a whole video all about them.
"How about that?"
Adapting to and thriving in extreme ocean depths
is what these animals do.
And that’s what makes them Crazy Creatures.
