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.
