00:00Speaking of artists, if you're fond of underwater photography,

00:03you can catch a lot of things underwater.

00:05But don't be too hasty with your search

00:08because there's an enemy in capturing images,

00:11and that's Dida in the story of Amazing No. 2,

00:14the cameraman of the planet.

00:16Let's talk about the eyes.

00:19The eyes of animals have been created

00:21more than 500 million years ago.

00:25It started with a simple eye spot

00:27until it was developed in different, weird ways.

00:32From the simple eyes of a scallop

00:36to the unique compound eyes of a mantis shrimp.

00:39The weirdness of the eyes of an octopus, squid, and cuttlefish

00:43is also on a different level.

00:45This is the recebo.

00:47This is the head foot.

00:49It's also known as cephalopods.

00:52Of course, it doesn't lose its tentacles.

00:56And the head has huge eyes.

01:00These are out-of-this-world eyes

01:02that can detect light.

01:05And they can focus simultaneously.

01:07The eyes of other octopuses have built-in light

01:10so they can see in the dark.

01:13It's really an alien creature.

01:16It's still a big mystery

01:18why the cephalopods look like this.

01:21In 2018,

01:23some scientists said that

01:25the octopus' eggs

01:27may have come from a frozen comet.

01:32But other scientists doubted this.

01:37They even believe that

01:39the eyes of the cephalopods are more simple

01:42like the nautilus.

01:45The nautilus is the most primitive

01:47of the living cephalopods today.

01:50They are the only ones with an external shell.

01:52And they are also the only ones with poor eyesight.

01:56Half a billion years have passed.

01:592,500 nautiloids rule the ocean.

02:04Now, only six are left.

02:06The biggest of these

02:08is the pearly nautilus in the South Pacific.

02:11It sinks when its body is filled with salty water.

02:17It can swim up to 800 meters

02:20before it explodes due to the pressure of its shell.

02:23But it has a problem with its eyes.

02:26It's open while it's in the ocean.

02:29And it doesn't have a protection lens or cornea.

02:32Its eyes are really unique

02:34because it's like a pinhole camera.

02:37This image is more blurry

02:40compared to what the octopuses can see.

02:43At least, they can still see something.

02:46As time goes by,

02:47lenses and other features in the eyes of cephalopods develop.

02:53Their eyes look different from the eyes of vertebrates.

02:56But it's really amazing.

02:59Their retina has no color receptors.

03:03But they can see colors

03:05with the help of their horizontal pupils.

03:08And instead of changing the lens to focus,

03:12they move it back and forth like a camera.

03:18Their ability to focus doesn't change.

03:23But it's not just the clear eyes

03:25that are the secret of their intelligence in hunting.

03:28Their brains are also there.

03:30Unlike anywhere else on our planet.

03:34This is just an ordinary octopus.

03:38Its central brain wants to hunt rocks.

03:41It orders its other brains to do what it wants.

03:46At the same time, it's independent

03:48in solving the problem of each brain in each body.

03:53Two-thirds of the octopus' brain cells are in its tentacles.

03:58It helps in processing visual information.

04:01In short, they can see using their body.

04:05There's one thing the octopus can't do.

04:08It can't breathe.

04:10It only breathes in the water that's accumulated in its body.

04:14It has two hearts that pump blood into its tentacles.

04:18The third heart is in charge of other organs.

04:23Could these be aliens?

04:25Or maybe they were just created to kill the octopus.

04:32In the ocean, there's a solution to every problem.

04:35And no matter how extreme it is,

04:37it doesn't matter to those who don't know about aliens.
