- 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?
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 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
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
"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
0:24 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!
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
ooooo star fish feet pics
Hot
mm yes~
Dat give me chills idk why
Star fish with no brain: dominates the oceans.
Me with a large human brain: can't find a job.
You have to compete against your peers who have big brains too!
It's not your fault you can't find a job most of the time, sometimes companies want something very specific, some people also get jobs but don't work at them and the jobs you're more likely to be employed by don't have the pay you want
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 😉
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.
I can only think of one thing and that is...
"Is this the Krusty Krab?"
*No, this is Patrick.*
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.
3:27 its just look like a hundred if people hiding in a starfish with their legs out
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.
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 CZcams
Oh my! An asmr addicted spotted! 😂
The creator of Spongebob really did make a scientific representation of Patrick, being brainless.
the reason why Science is my fave subject when i was young because of these topics. great video! 😍
This really made Patrick's character design make so much more sense. Great episode like always.
I always love watching your channel 🤗 I love science 🧬
Glad you enjoy it, Ethan!
@@KQEDDeepLook noice
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.
Deep Look: "What they don't have is a brain"
Patrick: "For real tho?" 🥴
Did she lie tho?
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
Humans and Starfish have more in common than you think, they love mussels and we also love muscles 💪🏻
Deep look doesnt get enough attention with these high quality videos! More people need to acknowledge Deep Look channel!
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
00:56 "what they don't have is a brain"
Me: exactly patrick!
OOOOOOH GOT’EMMMMM
3:36: That skinny starfish is very fast
Mussle: happy vibes
Starfish: I'm about to end this man's whole career
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! czcams.com/video/_IoOJu2_FKE/video.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
I have been binging these videos all week. They are the perfect size to get just enough information in, but also also still so entertaining. Like you’re not going into the deep, specific, boring details, but you’re still giving us enough to feel pleasantly educated! Keep it up you guys! I love it
Deep look is one of those teaches you stuff you never knew channels
And it’s amazing
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.
They're the favourite animals of my father in law.
One of the best and my favorite educational channel. ♥️♥️
HI!!! I love your channel so much I watch everything you post. LOVE YOU GUYS
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.
I Swear i can trust deeplook everytime! No clickbaits good content, what More would you need?
Starfish smell with their feet and butterflies taste whit their feet...wow.
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..
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🍻
Amazing!! Thank you Deep Look!
You are welcome.
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!
"What they don't have is a brain"
Oh that make total sense for how Patrick act
Neither do sea sponges for that matter
LOVE YOUR CHANNEL DEEP LOOK!
Amazing! This is another great way to learning English. Thank you channel.
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.
lauren: starfish are hunters, voracious predators that scour the oceans for prey.
starfish: *wiggle*
Starfish just looks like a cute underwater tarantula kind of creature.
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...
0:24 God, I'm horrified
Excellent effort a big thanks who are all involved 👍
One of the best channels on youtube!!! Keep it up!!
Is this... Is this it? Am I finally first on a video? Quick, think of something funny!
When you thought a starfish is squishy and fluffy but they're actually hard and rough
And disgusting
Good ol' KQED. Informed my youth growing up in the sixties. And still going strong. Thanks for your continuing concern with reality.
cheers from rainy Vienna, Scott
Wow, this is fascinating! Thank you!
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
YAY! My name is in the Description! I did it!
I really love your videos !! All my curiosities are explained in your channel ! A big thanks to u for that❤️❤️
This grows my love for marine biology

This show of how amazing nature is! 🌲🐚
First one to comment
* czcams.com/video/IXvOGR027GY/video.html *

More to come! We make 20 videos a year. Our next video is about sea hares, BUT DON'T TELL ANYONE
This honestly makes me happy! Just sooo beautiful!💎
Thank you 😌 I love your channel
0:58 “what they don’t have is a brain”
I can relate
love you guys! Keep continuing!
Found this randomly And I’ve been addicted always waiting for the next vid to drop

U hv the best channel, idk why ppl don't know about u :(
Amazing! Have never thought about starfishes, so it's really surprising for me. Thank you!
''I was happy floating, staring at the stars''
Amazing as always!
wow!! love the animations and editing
Thank you so much!
Star fish : gallops*
Sea horses : are you challenging me?
Sea Snail and Sea Slug, "Meh"
Bestest animation ever+ information
New Fan Here!!
I Really Love Nature And Science
Your channel entertains/teaches me everyday🤓
Simply amazing, high quality content..
Glad this is on my recommendation list ❤️
This channel deserve a millions of subscriber.!!!
Fascinating, I had no idea that their movement was so complex...and simple :P
I think this channel deserves more then 3million subscribers. Love your videos☺️
We appreciate it, Jill!
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
I never knew stuff like this until i subscribed to deep look :)
*Someone;*
:Hey star! How many legs you have?
Starfish: *"Yes"*
Very educational.
Hope for more videos. ❤
i've watched almost every episodes! this is a great channel
