- Thanks to MBARI and Monterey Bay Aquarium for partnering with us on this episode of SciShow. All of the amazing deep-sea video you are about to see was taken with MBARI's remotely operated vehicles! Head to mbari.org to learn more about their mission and latest research.
Salps are more than just strange balls of goo drifting through the sea-in fact, they’re more closely related to us than they are to jellyfish, and play a huge role in marine ecosystems and the global carbon cycle as the “vacuum cleaners of the ocean”!

This video salps!! Great job fronds!
Lol
Good job
I LOVE the Monterey Bay Aquarium!
Haha, nice.
That joke slaps yo
I thought you guys found my cousin Sal. He's been missing since 09. Last seen doing calisthenics by the dam. Got my hopes up Hank. Then dashed them. *Thanks Hank*
Why is their name so satisfying to say?
S a l p
s a l p
for me its reversed. SLAP would be nice one, salp is a buzzkill
Strong phonetics, kinda rare in english
s a l p s t o n k s
because it rhymes with SCALP
Weird I was googling Chordata and trying to understand where they fit in the tree of life. I didn’t quite realise that some Chordata are non-vertebrate though. Like these salp seem very similar to the microbes on your other channel so I was shocked when you said they are 10cm long.
yeah, Salps, Acorn Worms, and Starfish (and kin) our are close non-vertebrate relatives, the Deuterostomes, the other side of that are the Protostomes, ie Arthropod, Worms, and Molluscs. Jellyfish, then Sponges, then Comb Jellies, being the really out there species.
i remember going on a school trip to a beach for a week and kayaking in the ocean. one day we saw these in the water in giant chains and threw them around because we thought they were jellyfish eggs. 💔 rip to them, none of them left ok one price
@@asaenvolk technically after protostomes our next closest relatives are xenoaceolomorphs, and then cnidarians.
@@Rudol_Zeppili while your not wrong, Xenoaceoloporphs are between Nephrozoa (Deuterostomes and Protostomes) and and cnidarians. But Placozoa are between Planulozoa (Jellyfish and Bilateria) and Ctenophora / Porifera.
Then there is the fact that Ctenophora (comb jellies) and Profifera (sponges), never mind the who sponge / glass sponge arrangement is highly debated.
I was trying to make it simple for people.
" Hey look! Ha-ha! There goes a whole herd of clear, prosthetic lookin' rectum thingies ! " Sci Show: " They're called 'Salps' & they're related to you." " ....they're magnificent !"
How come I never heard of them before???
@@sandrastreifel6452 deep state obviously
Invertibrate cordates...! Huh... I learnt something today
Well, I would include some politicians in that category.
@@Carewolf unfortunately, spineless bureaucrats are not a carbon sink
Learnt?
You have a unique talent of making any subject interesting, informative and entertaining. Thank you!
Salps are one of my favourite groups of animals and I'm glad they're finally getting the love and appreciation they DESERVE
My mom explaining why I need to be nice to my weird relatives.
@Ben Louis I stopped believing in fairy tales a long time ago
We had a TON of these washing up on the beach in RI last year, and it was EXTREMELY distressing that I had to keep dodging weird almost-clear blobs in the sand. They look like a big bubble at first, but up close/under light, you can see structures of some kind inside them (maybe they were larval, and I was seeing the “not-a-backbone” thing?). I googled til I figured out what they were, determined that they were alive, and then got really sad and had to stop walking too close to the water’s edge for a while bc I felt too guilty if I stepped on one 😕 I also drove everyone around me crazy talking about what they were and explaining that they were more closely related to us than to jellyfish, so…..yeah this is why people don’t invite me places isn’t it 😅
They look like a new animal, like the world got a patch update
Most of the coolest things about our planets have probably not been discovered yet
Tierzoo needs to update the ocean tier list
You're comment is funny because od the gamer lingo
Just say you are a noob to the marine server. :P
No it’s more like discovering a new feature originally believed to be a useless bug
Salp poop: coming soon to a seafood restaurant near you...
Happy Holidays Hank!
The immediate pun nearly took my damn life omg
Genetically, EVERYTHING’s our cousins.
I've always wondered why this is the case you would think that different lineages of creatures would have sprung up but nope
@@bland9876 I mean, it's possible life has risen more than once on this planet but if it has, either the other lineages have evaded our detection or they're so similar to us they might as well be cousins.
One thing to remember is that the currently accepted theory is that there was little to no multicellular life for close to 3 billion years. Idk for sure but it's possible many animals last shared an ancestor with humans before either lineage became multicellular. If your last common ancestor was an amoeba, you can be forgiven for not seeing the family resemblance.
@@artemis_smith Also our techniques at least here on earth primarily rely on DNA. Bacteria have it, viruses have it, and eukaryotes have it. So unless separate lineages also ended up with the same DNA they would be extremely difficult to positively identify.
Not rocks :>
@@bland9876 A guess from my part: simple lifeforms (like bacteria) can exchange genetic information, so some researchers suggested that the base of the tree of life might look more like the roots of an actual tree; instead of one lineage giving rise to all others, you have several fusing into one. My guess would be that life arose separately many times and all these lineages became one or went extinct due to being outcompeted by the one super-lineage
I saw dozens of salps in the North Pacific, another lab group on the NASA funded EXPORTS cruise caught a bunch of them in their nets. Their poop looks like soggy Mini wheat cereal (you're welcome for that comparison).
I no longer miss that cereal. Thank you...I think.
I misread the thumbnail as "Our cousins, the scalps"
Lol I read " our cousins, the slaps"
Nice video! Tunicates are really amazing creatures and far too often ignored. During one of my field trips I collected loads of different sessile tunicates. It's actually so fun to have them in an aquarium and drop food for them inside. Even a single tunicate will clean a decent size water tank in an hour or two, the water turns from cloudy into clear visibly. It's also fun to drop ink in front of their mouth. They just push it right through and at their aft it comes out like smoke out of a chimney.
Hank Green: [hypnotic onomatopoeic sussurations]
also Hank Green: POOP!
Did you mean: susurrations?
All knowledge I learned about salps was wiped away when the otter scratching its tummy came up.
It's so fluffy! Of course its tummy would itch.
Anyway, great otter vid.
"Begun the assault of the clone salps has."
I’ve been adoring this channel for years... and I’ve never run out of interesting videos to watch!!! There is so much content on this channel it is truly amazing
Chicken of the sea, vacuum cleaners of the ocean.
I’m really curious to know how good they taste- yes, mostly likely they taste like salty jello, but I’m sure they could take on other flavors if cooked in soups.
Finding out how creatures taste IS an important part of science, after all!
They look like fancy plastic packaging. Good thing they aren’t! 😅
Correction, fancy plastic packaging looks like them
@@Sinaeb exactly
@@Sinaeb ooh you right
Nature has adapted to mimicking plastic packaging
Which is probably why lots of sea animals eat plastic things... and then get in trouble.
I feel absolutely privileged to see this video. It had my full attention because wow... Hank you are a really fantastic narrator. Mesmerized me the whole time and I think those squishy little thingies uhh Salps yeah they are the bombbb Everything in this video was excellent,; the editing, the narration, the source material, the scripting, Fantastic job SciShow & Friends!
I learn something every day...as long as I watch an episode of SciShow :). Totally awesome episode!
Hears about Salps for the first time...
Maybe the grey goo was here all along. 😧
Thank you
Utterly fascinating!
Single Salp Swarm.
Try saying that ten times fast!
😝🌪️
Single salp swarm sustains seafloor systems.
@@timmcdaniel6193 this needs more visibility.
Nicely explained well done
Ah my family saw these for the first time at the beach back in October!! Super cool to have a video made about these wonderful and strange creatures!!
Are Salps able to help fight those dangers red algae blooms that have occurred more often?
These are fascinating!
Have a great Yule season everyone! 🎄🤶🏼
love the monterey bay aquariums videos
Thank you for this information :)
Amazing!
What do they taste like?
QTNA
Probably not far off from water.
I love these things!!!
So, Salps are like Tribbles, you feed them and they reproduce. A lot. 🤔
Don't think they look as soothing to pet as Tribbles though.
I'd like to see a chain of salps puffing their way along. It must be fascinating to see all those little critters working together.
I’m going to be doing a solo RPG called tending, where you tell the story of a devotee at a holy site. One of the possible sources for the religion is Salps. I didn’t know what they were, but I guessed there would be a Scishow vid about them. Thank you for the informative and interesting video!
A "Salp Chain" huh?
Kinda like a *"Human Centipede"?*
;-) :-D
Eww
No pls no more memories of this
@@warricklow4218: If you watched it, that's your own fault.
I LOVE Monterey Bay Aquarium! If you live in California and have never been there, you're MISSING OUT
Cute alliteration, I love it
This is why I love RUclips!!!
great video!
"Its important!"
It's amazing that these animals can do all this by just evolving by random chance. We also know they are related to us simply for having a rudimentary spinal cord for part of its life cycle. Incredible!
i learned so much
Awesome video
Ah, very nice. Another video
weird... the salps i know here in Brazil are more like 1 cm long... I wonder if it is a different species.
Nah 10cm is just the _maximum_ length: there's lots of species of salps and they can come in all sizes! :)
There are about 70 known species, so a good bit of room for variation
I LOVE THE MBAQ. Favorite place in CA.
your videos are really informative> :)
Hank I'm convinced you either give yourself the best topics of discussion or your exceptionally good at explaining things..🤔
Hank: salps are cordata
me: spits out drink, WHAT??
yep look at the larvae with its tadpole like body plan a "head" with a simple brain focused on coordinating the muscles in its tail and a notochord (primitive backbone) which supports those muscles on its tail. These are the defining characteristics of chordata. The part that really should make you spit out your drink is learning that as tunicates (which salps are free swimming species) maturing to adulthood involves their brain and notochord getting reabsorbed.
They basically go from tadpole like animals to gelatinous blobs with a circulatory system kind of horrifying to think about but that is evolution for you...
@@Dragrath1 they stopped to think and didn't start again
Gosh, I had to check the date to make sure it's not 1st April today. How did I not know about Salps? They're awesome!
This video really salps!
i remember taking these and throwing them around in kayaks with my classmates on a school trip. good times 🤧
And yet, they have stronger backbones than politicians... :P
What
I saw salp while on a pelagic trip that left from Monterey Bay. They were pretty cool looking.
never heard of salps before, but they seem cool!
Scientists are contemplating optimizing salp poop... thats really kinda wild. Imagine some salp "oh yeah, those humans stopped by and my poop has never been better"
Salps could be used as a model for filters to remove micro plastics from the ocean.
How have I never heard of these crazy creatures before? They are insane. Also did you see? I did an alliteration. Nice. :)
0:16 sea walnuts are also lobed comb jellies
Hank !!
Cloning gelatinous replicators just like in Sci-Fi.
@@avw5kt Yep, Sci-fi is late to the concept.
Yo I live by that aquarium, it’s dope as hell
This sea superstar poop filled episode is so exciting, my heart is salpitating...
A few seconds in, I was like "oh no! It's the weird sea squirt connection again!"
Seems like our cousin is doing a better job in preventing climate change than humans are. I'm in my late 50's and knew 20 years ago if we don't move quickly on addressing climate change- things will get real bad for all life.
I didn’t know about these until I searched for tunicates, I saw about those on a wikipedia article when I clicked on a certain genus that frogs belong to. They’re so interesting!
"Salp bodies rapidly disintegrate in the stomach." As a survival trait, easily digested does not sound promising. But they make it work!
0:17 _Goo-dness gracious, great balls of goo!_
Aww, those poor salps.
_Cnidaria_ -- the only word I know of personally that begins with a silent "C".
I didn't know before I watched this video, though.
I've been pronouncing it with a leading "S" for years.
Salps are also new to me, but I'm mighty glad they're around,
they're not only our distant cousins, but also our allies against climate change!
I know there’s lots of science to do, but if you could just always collab with MBARI and the @mbaquarium, that would be great, kthnks🥰
He loved that heavy pooping joke. 😂😂 It's the little things .
I thought the thumbnail said "our cousin that slaps" not what it said but I would argue that salps do indeed slap so still accurate
Wow. That's amazing. I've only consumed beans and coffee today.
Good
i've seen them before, in our vacation but they don't look like alien thingies featured but they look like small chains of rectangular jellyfish
Back on Halo, you tried to kill Chordata. You tried to kill me.
♥️Hank
Can they filter out micro-plastics? That'd be potentially useful.
potentially? Bit of an understatement...
Or it could kill them off. That would not be good.
Perhaps we could breed a variant that can metabolize hydrocarbons in addition to everything else.
@@jared5811 they are, already are, it's just a question of which ones.
boy oh boy does this video make me wanna fund salp research lol
Heck I'm thing of these as a way to filter plastics. Design floating pumps based around them that just filter microplastics
Yooo I’ve never been this early!
That would be really interesting if true. Has there been testing on the genome? If not, it could be an example of convergent evolution.
Salps are a lot like us.
Poor Salp
Never heard of these critters before. Salps.
I'm posting this to raise awareness about the largest protest ever in history of mankind currently happening in India led by farmers, which is being suppressed and sidelined by fascist government and huge corporates.
It's really painful to see the media turning a blind eye towards these poor farmers fighting for the rights my means of non-violent and peaceful protests.
Please put in the effort to learn about the plight of these farmers and stand with them in these dark times to honour those who laboured to put food on your table.

Small correction: μM (micromolar unit of concentration) μm (micrometer)
tiny aquatic tribbles!
So what I'm hearing is that we need to genetically modify salps to be able to clean our water and air.
It'd be cool if they could be gengineered to digest micro-plastics.
you would think with the rate of growth witnessed in these cousins of ours they may be a genetic key to research when it comes down to cancers or regenerative healing
Car salesman: *Slap some Salp*
This plankton more related to human more than jellyfish
Ok from now on salp is my favorite cousin
