- They may look cute and colorful, but starfish are actually voracious predators. To sniff out and capture their prey, they rely on hundreds of water-propelled tube feet, each with a fiercely independent streak.

On a visit to a friend’s lab in Tokyo, marine biologists Amy Johnson and Olaf Ellers witnessed something they’d never seen before. The starfish in Tatsuo Motokawa’s lab weren’t content slowly gliding across the floor of their tank, they bounced and galloped, zooming around their enclosure.
For one of the most familiar animals in the sea, this was a new behavior, never before described in the scientific literature.
“It was an absolute epiphany,” said Johnson who studies how sea stars move and teaches marine biology along with Ellers at Bowdoin college in Maine. “ That moment we first saw them bounce completely transformed everything we were planning to do with our research.”
Since then, Johnson and Ellers have worked to change the way we understand these animals who have successfully made a home on this planet for at least 450 million years.

What do starfish eat?
Most sea stars are predators. They hunt a variety of marine animals including bivalves like mussels and clams but also sponges, snails, algae. Some sea stars are scavengers that consume detritus.
How do starfish breathe?
Sea stars mostly transpire through their tube feet which have very thin walls. Oxygenated water travels to other parts of the starfish’s body through its water vascular system.
Do all starfish have five arms?
Nope! There are many types of sea stars and while most have five arms there are stars with fewer or more. Sea stars have radial symmetry, but may have evolved from a bilateral ancestor (with right and left sides).

So you're telling me is Patrick made a big deal out of having no nose, when he had them on his feet the whole time?!!
indeed!
Woah?
@CharlieMHz 😂😂😂infeet
its more like his back to us tho
Is this why Patrick covers his body with the food he eats?
ooooo star fish feet pics
Hot
mm yes~
Dat give me chills idk why
I just learned so much about Patrick...
I think he’s onto something more than he lets on.
There is something more in that Space
Deep look can tell me about cyanobacteria
I super recommend journey to the microcosmos for some amazing content on cyanobacteria! You don't have to watch from the beginning, but that's what I recommend to new viewers!
deep look: uno reverse card*
Remember when cyanobacteria was called blue-green bacteria
@@matthewhinojosa4642 NERD! jk XD
@@kf10147 That channel is so good!
This is so awsome! I have Watch some of your videos! Your so cool :D
Aside great contents, I think the Foley artists who gave the sounds of this video are amazing.
For some reason, it's 3 am and I'm out here thinking... how tf do starfishes work? Now I can go back to sleep, thank you:)
Good night! 😴
I love this channel
Their entire body is their “brain”. Their cells just aren’t grouped together to resemble what people normally think of.
I was willing to see this movement through animation and luckily by this channel i got it thanku u so so much it made me understand the water vascular syster in starfish 😁😍
"Helow everyone, this is YOUR Daily Dose of Internet."
i love you deeplook
You are welcome Michelle.
That explains lot, packrick star didn't have brain😂
No BRAIN! No headaches!
🧠
أجمل قناة على اليوتيوب ⚘💙
patrick, is that you ?
I collected some Sea Star in a bottle. They are cannibals eating their own dead kind peaces.
So you’re telling me starfishes actually move? I just thought they stayed in one place 🤦♀️
At 3:09 y’all seen that right?
Most animals in the animal kingdom: "We have evolved complex brains to help us move around, to collect information, hunt, and survive"
Starfish: " *FEET* "
Jellyfish:TENTACLES
Urchins:SPINES
MORE FEEEEEEEEEEEEEEEEEEEEEEEEEEEET
@Captain Bruh I already know bruh
The biggest groups of animals - molluscs and arthropods (about 80-90% of animal species), they don't have complex brains.
this learning content is so good my teacher even used it in class
Excellent!
Cool
To be honest teachers'll use any video in class
Lucky. I only get boring cringy ppts and docs in my class
Bro same i also shared some of this with my first teachers, so they can use it on their classes with the new guys
deep look is the best channel on youtube. They never sugarcoat info and always leave me fascinated
Glad you think so!
And they actually reply lol
This channel is incredibly underrated.
You'll never get used to it
i strongly agree with this comment
Is that an bad think?
I kinda dont get the difference between overrated or underrated
Can you tell me
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as Asteroids due to being in the class Asteroidea
The “star” part in their name is a reference to a famous marine biologist and his special power.
I love how the words 'brittle stars' sound together. Very poetic.
@@vbgvbg1133 The same marine biologist who also got his doctorate degree because he wrote a thesis on starfishes?
@@parkchimmin7913 Exactly
I'm sorry Spongebob.
Actually, you're right, sea stars do indeed eat sea sponges
La REFERENCE!
r/stillinthesimulation
"Do you know how seastars feed, spongebob?"
"Let me...
...Show you."
Thanks for reminding
"whichever arm pulls the hardest takes the lead"
so basically starfish are just five conjoined worms fighting for dominance. very metal
Oh no I was trying so hard not to think of starfish like that o h n o ;;;;;
That is the best sentence I've seen in my entire life
0:56 "What they don't have is a brain."
Starfish confirmed to be politicians.
Nah, those have inner cunning. The homini without the brain are the ones who vote for those politicians.
@@DzinkyDzink nah those are the ignorant, willfully or not, and decieved. Those who don't have brains are starfish
@@freshmilk7122 We've come full circle then...
Don’t diss on starfish like that
@@Laura-Yu You're right. Starfish are more intelligent than politicians. My bad.
0:24 Imagine if they really we're that quick
That's horrifying hahaha
They be the nopest of the sea
they move like the other father in coraline
@@slugshop6 OMG LOL
@La Lupina Look up sea spiders then 😉
0:24 I always liked the sped up footage of starfishes moving around. It looks like a sea roomba which is funny to me.
lol
Now I can't unsee it
Sea roomba!
Hey the SeaStars are like me
We stay in one spot and only move to eat
Everybody gangsta till Patrick gallops towards the baby scallop. To eat it.
Deep Look: "What they don't have is a brain"
Patrick: "For real tho?" 🥴
Did she lie tho?
I can only think of one thing and that is...
"Is this the Krusty Krab?"
*No, this is Patrick.*
3:27 its just look like a hundred if people hiding in a starfish with their legs out
This is so fascinating to watch... ASMR in their own way

I see you everywhere...
@@jeweldimapilis2284 But hes not a bot, i think. OwO Is
Ray Mak Was Every where In the world before the pandemic but know he is every in RUclips
Oh my! An asmr addicted spotted! 😂
The creator of Spongebob really did make a scientific representation of Patrick, being brainless.
I always love watching your channel 🤗 I love science 🧬
Glad you enjoy it, Ethan!
@@KQEDDeepLook noice
the reason why Science is my fave subject when i was young because of these topics. great video! 😍
The more I learn about the biology of all kinds of animals, especially those in the ocean, the more I realize how utterly bizzare life actually is.
Is this... Is this it? Am I finally first on a video? Quick, think of something funny!
Could you make video with Yeti Crab and how he farms food bacteria in his furry arms?
Ooohhh we will have to look into that.
I love how deep look responds to these comments
Looking back, their relatives are like parts of one starfish; the main body of a starfish is 1 sea urchin; a sand dollar is a flattened out sea urchin and a sea cucumber is technically 1 foot of a starfish.
Their relatives the starfish also look like one another. The basket star is a fractal-armed version of a starfish; a crown of thorns is like a multiple armed starfish and the crinoid is a stemmed version feather starfish.
Humans and Starfish have more in common than you think, they love mussels and we also love muscles 💪🏻
00:56 "what they don't have is a brain"
Me: exactly patrick!
OOOOOOH GOT’EMMMMM
And people say Patrick doesn't have feet
So your telling me that one of my favorite cartoons characters don’t have a brain
We are telling you that one of your favorite cartoons characters does not have a brain.
walk around Bikini Bottom
always looking for food doesn't care clean or dirty
doesn't had job
don't have brain but still a genius
stay at rock
yup that's Patrick
@@leongliyang6946 but somehow have money to buying krabby patty....
@@YourFriendlyShapeShifterFriend i guess he found it 1st before Mr.Krab does...
@@leongliyang6946 ye...
How about a Deep Look at ticks? Apart from mosquitoes they're among the most feared/dangerous *common* insects in everyday erh parks and recreation life
We have done ticks - enjoy! ruclips.net/video/_IoOJu2_FKE/видео.html
*arachnids, not insects.
@@KQEDDeepLook Oki, i must have forgotten, i'll rewatch now, thanks!!
@@Sara3346 Thx, good word!
Not many channels are willing to travel back in time to appeal to their audience.
"What they don't have.... Is a brain." everyone talking about me
This really made Patrick's character design make so much more sense. Great episode like always.
They're the favourite animals of my father in law.
Deep look doesnt get enough attention with these high quality videos! More people need to acknowledge Deep Look channel!

@Kal Widorn the pirate captain. THAT, sir/madame, is HILARIOUS! THANK YOU!
3:36: That skinny starfish is very fast
Starfish smell with their feet and butterflies taste whit their feet...wow.
fun fact: when starfish eat they regurgitate their stomach, release enzymes that break down the food then absorb the broken down food then live happily ever after
"What they don't have is a brain"
Oh that make total sense for how Patrick act
Neither do sea sponges for that matter
2:28 Why was that so cute?
I honestly didn’t know that starfish moved, I didn’t even know they ate,, I thought they were cute rocks called starfish. I love how much this channel teaches me🥰🥰 thank you
I'm glad my feet don't smell.
Because my shoes sure do.
HI!!! I love your channel so much I watch everything you post. LOVE YOU GUYS
0:24 God, I'm horrified
Well done! Renewed interest on this simple-looking-but-longer-history-than-ours creature. Observing their behavior/ locomotor mechanism like reproduced here is a rare chance. Biomechanically, galop appears impossible for them. Actually inspiring.
Starfish cute? To each is their own i guess.
YAY! My name is in the Description! I did it!
Mussle: happy vibes
Starfish: I'm about to end this man's whole career
I loooove watching your videos! I told my animal science teacher about you guys and we watch it in class now :D
Yay! Thank you Naomi!
Maybe I should tell my teacher too, that's a good idea..
lauren: starfish are hunters, voracious predators that scour the oceans for prey.
starfish: *wiggle*
Lovely 🌹🌹🌹
Though disgusting in some places, I hate slimy things
I like observing things like those from a distance
Yeah, the part of the ampullae, very disgusting for me
I see why the jokes about Patrick not having a brain and nose is made in spongebob, interesting
Love echinoderms 💜

I love the videos of this channel😍They are really fun and interesting to watch... This channel is indeed underrated... Also a request to you guys.. Can u all please make the videos longer? And can u make videos about Space? That would be great. Thank you.
Considering that this is a biology channel centered on macro photography, I'd think not. We've observed only one biosphere, after all. Try SciShow Space, perhaps.
Deep Look is part of PBS. They have loads of other, sciency channels/programs.
waitwaitwaitwait are you telling me...that if a starfish were to crawl all over me, it would leave tracks? i love it
When you thought a starfish is squishy and fluffy but they're actually hard and rough
And disgusting

0:58 “what they don’t have is a brain”
I can relate
Amazing! This is another great way to learning English. Thank you channel.
These Starfishes Survive Without A Brain
Which Gives A New Ray Of Hope For My Colleagues
Phylum Echinodermata....my biology teacher shown the video for better understanding...me still remember every part of it. I love zoology
I Swear i can trust deeplook everytime! No clickbaits good content, what More would you need?
Fun fact, some star fish are actually considered pests in parts of the ocean. I had a biology Lecturer who did her PHD on how to get rid of them without harming other sea creatures.
order from Chaos? This starfisch is so much order we will never be able to completely understand it. It even has so much order that it doesnt even need a brain because it is so well "programmed".
One of the best and my favorite educational channel. ♥️♥️
But if patrick is a starfish becuz his brainless, why squidward who have 3 hearts is so grumpy :(
Thank you deep look!!! I'll save up to make a donation soon, my nephew loves these. So much thank you! Hope y'all stay well and have fun🍻
*My ap chem lab report due in 40 min*
RUclips: _ever seen a starfish gallop?_
And then he puts his whole stomach outside around the clam to digest it alive.
Isn't nature beautiful?
*Someone;*
:Hey star! How many legs you have?
Starfish: *"Yes"*
*MY TRYPOPHOBIA IS SHAKING...*
This is why I'm actually scared of starfish- (shudders) I hate all their little feet- I'm sorry-
“What they don’t have,is a brain” that explains a lot about Patrick
I was just reading about phylum mollusca and echinodermata,, was so curious about locomotion by tube feet,, now i know this. world of ocean is so vast, unexplored and fascinating, it leaves me with a sense of awe, these cute little animals are gift of mother nature, we should do everything to protect them from pollution and commerical hunting for useless, materialistic things. such an amazing channel🙏❤️
Anything with a radially symmetric body plan freaks me out
Excellent video. I never thought I would see a starfish gallop
But what happens if two feet on opposite ends start pulling to follow a scent?
All that's ok (i mean i appreciate ur effort) but how it eats the mussel?
“What they don’t have is a brain”
Me: OOOOOO ROSTED
"What they don't have is brain"
Well, that explain a lot of thing with patrick
Stop swimming so fast! I’ve only got 5 legs, and one of them is my head!
This is what I look like when I'm too lazy to get something when I'm on my bed
