Sea roomba eats a dollar.

[@BrianNguyenBeehive]

What a crappy roomba, it keeps spitting out the dollars.

[@ppbb6606]

ya they do

[@noahkimble8691]

@Roger Crew fuck off

[@laurelcook9078]

Patrick: oh boy, 3 am! *liquifies soft parts of sand dollars*

[@ambuck.]

LMAOOOO 💀

[@murriellemgl4479]

The way all these creatures are crawling is just beyond creepy

[@yul4206]

It's just been speedy up but yeah it's creepy watching it.

[@BazingaBane277]

your right starfish give me the creeps and chills

[@user-qg8xq9tp4w]

They must think(if they could) the same of us XD

[@humanleader184]

honestly i'm kind of numb to the whole "creepy creatures" shit, it doesn't bother me at all

[@folasadeadedapo]

Yeah...and yet so mesmerizing

[@truvelocity]

So, all of those sand dollars I collect off of the Huntington Beach Coast during low tide may have met their doom from that monster star fish?

[@jaimelojeda1904]

truvelocity Im afraid so.

[@skellingtonmeteoryballoon]

When you put it that way... Lol

[@jonathandonley3299]

Yeah. You were basically at a murder scene. ;)

[@sean123888]

Ikr I used to get em on the south jetty Oregon.

[@Zak-tk8wv]

Ues

[@mr.brouwer8083]

NO patrick nooo!!!

[@thatonecaryouwant]

@Rick O'Shay When you think about it I've never seen a sand dollar in Spongebob before.

[@jujuboi5860]

@Rick O'Shay oh no patrick is a murderer

[@satonyakwaii]

Well not just Patrick plankton(Remember that episode)

[@exumbra1399]

Hey, Mack. Whatcha in for?

[@XEinstein]

This video really makes you appreciate how great David Attenborough is: I mean even under water he still sound great!

[@dubiousdove782]

@Jamel Gianangelo 🧐

[@jadynakistrife9884]

It's kinda comedic how the brittle stars move away and back to their positions from the predator.

[@DaRkLoRdZoRc]

Hey man, they got shit to do. They can't just up and leave work because a giant Koosh ball is trying to eat them. That sand won't sift itself, you know.

[@pnkemoji]

this reminded me of claymation lol except this stuff is reaL

[@l.a.1254]

Yes!! Gumby lol

[@princealmighty5391]

You should make claymation

[@AneesaH.]

Half a meter a day?! That means you could literally watch it elongate before your eyes! I had no idea any phototroph grew that fast.

[@skiplegday4718]

around 2 cm an hour or 0,035 cm a minute

[@paddor]

If it just didn’t move around constantly...

[@AnimalEmancipation]

Some bamboos grow 91 cm a day

[@Flistered]

@@AnimalEmancipation I heard 3 feet

[@1toW4mB0to9]

@@Flistered thats.... the same

[@miiirky1904]

I'm speechless. First, the mouth of the urchin. Then the sunflower starfish! And THEN the dollar urchins skeletons... I... I... I... thank you, all the documentarists and everyone involved in this video to show us all this creatures from another world.

[@JessmanChicken86]

wholesome comment :)

[@retrofuture1989]

Those creatures are all from here on Earth, evolution has created a vast biodiversity of species in seemingly every form and shape, but they all got DNA just like you and me.

[@glenp.8241]

Narrator had to eat a entire stalk of celery to make the chewing noises

[@ems7623]

Not how that works. Look up "foley artist."

[@zenmaster8086]

After seeing the little sea urchins just running around just warms my heart

[@mim0so]

Spiny lil goobers just living the life :3

[@ACreativeWorks]

Not only is this channel shows how amazing nature is, but somehow reminds me of my childhood days.

[@debtrunner7929]

..of SpongeBob

[@billrobbins5874]

The warm voice of David Attenborough as narrator. Remember him too!

[@Pony_Stang]

I am now currently terrified of Starfish

[@DG-kq8zf]

Hunter Shadows The sunstars are rather squishy and soft with a boney feel. Not scary. But they move pretty quick as far as starfish go. Most of those hefty ones shown on the bottom were bat stars. I've spent literally hundreds of hours diving here in California. Mostly abalone diving. It's phenomenal here. Better than backpacking ☺️

[@DdesideriaS]

​@@DG-kq8zf When was the last time you saw one of those sea stars? Urchins have took over and eaten most of the forests after all of the sunflowers died off from the Sea Start Wasting Disease. I'm diving after fish almost every week and haven't seen a single one in almost tho years (NorCal)

[@stormboss57]

If you are scared of them hunt some down and cut them in half.

[@evilsharkey8954]

Storm Boss, then you get more sea stars!

[@DG-kq8zf]

Evil Sharkey Nope. You get a dead star. They only regenerate their legs.

[@chivo8665]

1:55 What are those? With the human eyes on top of them 2:04 What is that worm/slug/sea cucumber thing to the left? 2:13 What is that alien-looking arm in the top left corner? 3:29 Why? Why why why?!! This is why I'm not getting a diving license, mom.

[@hungidran1]

*this is why i want to get a diving license 😀

[@nancyngoasheng7806]

The ocean never ceases to amaze me

[@pappydoge1841]

I never really thought about the fact that the beaches where I live are covered in fresh kelp plants and sand dollars, but now I understand, something very gruesome happened here.

[@FoxDren]

Not really just 🎵 The Circle Of Life 🎵

[@Nicolacsika]

クモヒトデみたいなの出てきた瞬間 気持ち悪くて死んだw

[@CommanderNConqueror]

i never knew the sand dollar was a living organism until i watched this video

[@loumeimegueye8267]

Oh !the sea is another world full of unknown diversities.

[@kittykatBflat]

BBC Earth: Here’s a beautiful and educational nature video. Comments: Sponge Bob jokes.

[@malachiallen1517]

1:53 Traffic in a nutshell

[@danku-kun4551]

Why is nobody talking about how cool *"Urchin Barrens"* look and sound?

[@guys-in9vd]

sunflower starfish : * modem noises for 1h * brittle starfish : * moving noises * sunflower starfish : *M O V E O U T O F M Y W A Y*

[@kaytlinjustis5643]

Huh, so THAT'S what sand dollars look like alive! Only seen the white skeletons on the beach! ^^

[@nobodynowhere21]

The description of how they are ... consumed ... was totally metal. Imagine some scary monster extruding it's stomach onto and around you, bathing your body in digestive enzymes until your eyes, skin, muscles, organs, etc. were melted away in its ooze, then dropping your dry, whole skeleton in the dirt behind it. The thing of nightmares!

[@Nhatanh0475]

It doesn't have eye/skin/muscles?/organ or really anything to be left behind beside the skeleton.

[@user-sd6ny5cv1l]

スイチャンネルから来たけどやべーなｗｗｗ魔界すぎるｗｗｗｗｗｗ

[@eoulton1086]

LOL 😂😂😂😂 ITS SO FUNNY WHEN THE STARFISH TRYS AND EAT THE BRITTLE STARS 😂😂😂😂😂

[@user-to3iv9cy2q]

That tiny mouth of an urchin is very cute

[@soriyayon8350]

So thats how they make sand dollar😶

[@evilsharkey8954]

Soriya Yon, that’s how you find them in the wild, but when you buy them in a store, they were killed by people and then soaked and bleached to get all the dead stuff out.

[@vmanismyname1534]

Anyone else think of the show Always Sunny in Philadelphia, family feud episode, where the answer the guy gave to "name a food that has to be cooked" was SEA URCHIN

[@TheNecromorph1]

lmao, this just needs some benny hill music added to the fast motion scuttling of the demonic starfish and we got ourselves a show.

[@markfryer9880]

Far more entertaining than any Reality TV show that's for sure. Real life drama with a comedic twist.

[@ComdrPirozhki]

Sea urchins: eating all the kelp in the ocean Sea otters: *I’m about to end this man whole career*

[@fuhwurd]

TheCraftianChannel // TCC overused jokes but ok

[@mariannapapadopoulou905]

KBAC yes otters eat urchins!

[@jdtk312]

Imagine this video wasn’t speeded and they really moved that fast ! lol that would be so funny and blood curdling at the same time

[@MujakiKid]

Wow, I never before thought I could feel terrified of a Seastar! Run little Brittlestars! Run!

[@thenewaeon]

The sea floor is a horrifying, eldritch nightmare.

[@MarenAnne66]

It's really funny to watch these guys move when the film is sped up. I imagine the starfish with wheelies on.

[@bokchoiman]

I'm in utter shock..

[@shailonnoelle7175]

I've seen miles upon miles of urchins on the lost coast. A hole in the stone perfect for a purple urchin only a centimeter to separate them . Billions strong. It's incredible. And scary when you realize you just walked 30 yards without booties and this is your 3rd time surfing there.. idk how I didn't stop on one

[@lucpraslan]

It's an echinoderm paradise or killing field, depending how you look at it

[@emosasukelover222]

awww sea urchins kind of look like little sea hedgehogs owo

[@StephenGillie]

Trees are lungs turned inside out and urchins are stomachs turned inside out.

[@evilsharkey8954]

Sea stars literally turn their stomachs inside out! That’s how they eat.

[@hellobye4674]

This is terrifying

[@chancellorpalpatine8996]

Giant starfish and moving rocks!!?? Oi blin what is going on in the sea.

[@callmek.01]

Chancellor Palpatine did you call for me?

[@FelisBX7]

Toxapex are real and they're coming for our starfish.

[@nubbiewubbie7285]

Echinoderms are some of the weirdest animals on the planet.

[@TheAlps36]

Am I the only one who thought those purple urchins moving was kind of cute?

[@admiralcat3809]

Kelp forest became a giant echinoderm battle royale after a bunch of purple pompoms committed illegal logging.

[@buck9668]

The bumper cars sporting an eye on top are keyhole limpets. They''re not true limpets, but, like true limpets, they're cousins of snails and slugs (all being gastropods).

[@avrilanne13]

I never thought all of them actually move!

[@Angelo-bj1qu]

Is it just me who finds the sea urchin looks so cute 😍

[@evilsharkey8954]

Angelo, look up collector urchins. They find little pieces of debris and carry it around like camouflage.

[@nutzeeber]

Neptunus : " aahh yes, brittle star my old mop!"

[@freddieperez7567]

1:55 what are those sea creatures with a human eye-looking thing on their backs called?

[@mehhhhh421]

Echinoderms are so fascinating.

[@nicholasgerry6931]

Imagine you're driving, then touch your feet there on the bunch of starfish

[@ColorlessQuarky]

I would love that to happen, since they are very interesting animals.

[@uniikwa]

*seeing these creatures crawl around at high speed makes me clinically disturbed.*

[@Nhatanh0475]

0:25 I see... I seee... SUBNAUTICA kelp forest.

''they can grow half a meter a day'' that is absolutely insane for a planet, let alone any other living thing. good lord.

[@Ohlookitsdaisyy]

Half a meter a DAY?! That's amazing!!!

[@songofyesterday]

somehow urchins are sold as premium goods and tastes disgusting, I'm glad we have connoisseurs out there willing to save the kelp forests

[@DieFlabbergast]

Sea urchin roe - called _uni_ in Japanese, is a popular topping on sushi. I can attest that it is delicious, but a bit expensive.

[@moaidotahiti4869]

Looks like something bjork would want on one of her music videos

[@cjcares7815]

Finally I've discovered what was that I had found on the shore of Thailand🇹🇭. Skeletons of sand dollars they were!!!

[@everythingunique641]

@1:54 ROCKS WITH EYE BALLS AAAAHHHHH!!!!!!

[@edipasplays]

Sand dollars look like moving coins from stop motion clips from coinstar

[@dave1986R]

The Sea Urchins may destroy strands of kelp, but the Sea Otters in turn eat the Sea Urchins and keep their population in check. Especially in Monterey Bay.

[@isaacstone7899]

Amazed things in the sea.

[@happyboi1447]

Sometime I think sea urchins are pest that has no effect if they die But I sometime forget there is animals called Sea Otters

[@XEinstein]

Well don't forget they're also eaten by humans: Italians put them in pasta, Japanese on sushi.

[@happyboi1447]

True

[@evilsharkey8954]

That’s why sea otter conservation is important. Without them, urchin run amok.

Beautiful! Video Fascinating to watch! Thank you David Attenborough. 🇹🇴 CHCH NZ .🤩

[@Ilikebunnies-metoo]

Guess we have to eat more uni (sea urchins) now. I've never tried it, but I'm hoping it's tasty.

[@dandelion1627]

Nature hard at work to keep a balanced ecology so that human can have a livable environment and food sources.
