This is a species that hung out with trilobites *and survived what killed them.*
Now THAT'S impressive. Trilobites were quite possibly the most successful organisms EVER (aside from humans), and these delicate flower-things OUTLIVED them.
thanks captian obvious
@@flickcentergaming680humans haven’t been around anywhere near long enough to say we’re successful.
Are you silly? That's not how evolution works.
@user-ez2tq4vi8f
Why is your first instinct to insult someone for sharing a fact they think is neat?
Do you think of yourself as better and smarter? For what? Because you know a fact that someone else also knows?
Did nobody ever tell you that knowledge is not inherently latent in all of humanity, or are you the type to throw a toddler into a forest and say, "surely if it be truly human, it knoweth how to pick itself up, create fire, and clean the waters to drink of!"
Touching grass is not enough to ground you to reality.
You need to Piss your Pants, NOW.
Yeah, I love when one of the oceans filter feeding mops goes for a walk.
Shows a zest for life.
More like a swim
@@infinitejest441I'd hardly call the sea lily's motion "swimming", but I'm sure he's trying his best.
no no no. thats nightmare fuel. i hate it.

This explains the crinoid proverb: "Blood is the exact same thickness as water"

Absolutely underated comment. Literally made me laugh out loud.
Made me groan, have a like! 😂
This is what the internet was made for. Superb.
Surgery must be easy for them. Nurse, I need 50 cc of seawater.
I'm imagining crinoids as surgeons now 😂
@@catboy_official All the motions are the same, but when they move away the surgery is done.
And now they to get that much seawater without viruses.
Good luck.
"Doctor, his arm's off!"
"It'll grow back."
Interesting take. I was thinking surgery might be hard for them on account of the fact that they have no brain.
Sea urchin: *exists
Crinoids: "aight, imma head out"
Hi I’d just like to point out one minor mistake! The animal shown at 1:31 is not a stalked crinoid, it’s a type of polychaete tube worm. You can tell because the ‘stalk’ is smooth and unsegmented, and the feathery tentacles don’t have the right anatomy. There are also generally too many ‘arms’ present.
I had to go and look it up, that looks nothing like the ones I found on the internet all of the worms are segmented at that one you pointed out is not segmented at all. Now I having nightmares of these dam worms yuck…..
@@dawsie the worm itself is inside the tube. It creates a tube to live in, which is smooth, but the worm inside is segmented
@@dawsie they're cute lmao what are you even yapping about?
@@HealthXPotionsoh, you said yapping, guess you showed them for... having a subjective opinion.
Ah, the wonders of internet... There's always some knocker behind his keyboard out there, ready to strike at a most unsuspecting moment - *_Watch therefore, for ye know neither the day nor the hour..._* ;-)
Seriously though, I do appreciate your knowledge and you making the correction. Yes, most people watching this couldn't care less - like that "Health Potion" fella here, and speaking of "health" ("physical" or... "otherwise") I'd recommend him changing his, erm, "supplier" - because that "potion" he's using now apparently "ain't doin' him no good", but I digress here... ;-)
"before blood existed"
Using seawater as blood has gotta be the most interesting fact in this video. That's mind blowing and makes me think that our blood being salty has it's origins in seawater.
Eh, the salt ratio is not the same between blood and seawater
@@Carlos-bz5oo "the salt ratio is not the same"
So? I don't get your point. I'm not suggesting that blood is the same as seawater, only that it evolved from animals that lived in seawater and didn't yet have blood in their veins.
If you are going in the direction of relating the salinity of seawater to the salinity of blood, you need to start far away from humans. Currently I recall that the Na of sharks is normal at around 600+ mg/dL; for humans it is about 140 mg/dL. So 'when blood began' and 'the salinity of the oceans' are both variables.
@@janetchennault4385that seems like good places to start.
The cognitive light cone hypothesis from Michael Liven has been used in similar calculations already and seems like it could be applied here.
If we're looking at all life since we started having things like tissues and organs, so much of us is just "how do we get the ocean, in us, onto land?". Out circulatory and pulmonary system is the best thing we can do without sitting in the ocean and diffusing (instead, air just goes into our damp lungs and diffuses, and then gets shuttled around). All reproduction has been "how do we put baby in ocean?" Baby in ocean contained by soft pouch; baby AND ocean, contained in hard shell; baby and ocean, in special ocean organ (now with slightly less salt!).
I'm being reductive of course, but lots of evolutionary traits feel like they're doing something the ocean would have done for us, had we all just stayed like our distant cousins the cnidarians 😂
Ah, the ocean, the only place on the planet where animals can look like plants (without the use of mimicry)
many bugs do the same
Probably because it’s a lot harder to filter feed from the air.

I what way do they stick to you? Did you experience this? I'm fascinated by the thought because they just look like they would feel like a bunch of feathers.
@@SepiaMaddy They stick to you like velcro does on soft fabric. Yes I have, a couple of times, stuck to my wetsuit leg, but trying to unstick with hands doesn't work because they stick to the hand, luckily I always dive with torches, so I used one of those to remove them. The feel is kinda like glue-covered netting, kinda like those rubber nets you put under bathroom rugs, except stickier, and not as pliable.

Except it’s not a plant because by definition plants don’t move because by definition plant cells have cell walls.
You know what's wild? When I was a young kid we pretty much didn't know crinoids weren't extinct - it's wild to be a kid picking up fossils and then one day just see the living things themselves - I got so excited by the early footage
you: feather star
me, an intellectual: biblically accurate feather duster
I love how some really ancient life just keeps on living and it's still here with us (in a cladistic sense, of course species differ now, except in super rare cars they don't at all).
We still know so little about our deep past this helps to visualize how life could look like and better imagine it.
Crynoids, sponges, many branches of bacteria and archea are around for hair a billion years and more, and they very well be present half a billion or more years after us.
They not having blood blew my mind back when i was a child.
The e-coli in your gut predates all animals you can think of 😂 cladistically of course but basically it’s the principle of you don’t change a winning team 😂
@@dreammaker9642
Yep, many branches of bacteria can be over a billion years old as I've said.
And also tardigrades are around 550mya old, proven virtually unchanged since at least the cretaceous.
Or how Lepismatidae are over 400 my old and Lepisma saccharinum (still have to remind myself of it's gender change to this very day) itself looks virtually indistinguishable for well over 300 my old specimens.
An viruses predate LUCA who knows by how many millions of years... (As LUCA already had an immune system formed against them, according to a research paper released after my og comment. How cool is that?) I wonder if ever we may able to solve the ancient question unequivocally as wether viruses have evolved for more complex parasitic proto cells as most parasites do, or a whole different branch of life forming from the same building blocks in the "primordial soups" of black smoke chimneys and/or those special "chambers".

A correction for your correction video, at 1:32 that isn't a sea lilly, crinoid or even an echinoid, that's a feather duster worm and type of polychaete worm.

Yup. Completely different animal phylum. Crinoids are echninoderms and polychaetes are annelids. Also, corals are animals. Albeit different to what we'd imagine animals being, I suppose.

Uses ocean water for blood? Well, little acknowledged fact; Yeah, if you're Navy-Navy and a Navy kid, you know.... during hard up times? Seawater ultra-filtered, and ultra-sterilized (250f/0psi) can be used as basic Saline. I know it sounds nuts, but typical Saline is on par with seawater. Evolutionary touch marks are AMAZING!
Saline is just water, salts and glucose but it’s not sea water or on par with it. If you just IV yourself with sea water you’ll kick the bucket real fast cause one, not nearly the same dosage basically saline will replenish your electrolytes while just sea water even sterilised is going to shoot it up to lethal dose real fast. But point taken but you better off getting fresh clean water, sprinkling some salt and sugar in there. The glucose is important as it speeds the process of hydration for your cells.
@@dreammaker9642 I'm high as balls RN so take this with a grain of salt (pun intended), but I think the mass transfer is totally different from drinking seawater. Seawater pulls water out through colon like reverse drinking, but injecting seawater is increasing blood volume by definition of injecting. So if anything the colon would have like a more intense suction LOL phrasing.
I could see how it might lead to death if too much were added, but hospital saline isn't a perfect substitute for whole blood anyhow, so it's a matter of which thing kills the patient first: lack of living blood components or salt poisoning. As long as the blood components run out first it doesn't matter what the salt concentration is because the patient would have to be dead before getting sick, thus not getting sick for realsis.
But even if that is the final problem, it's not the correct comparison to be making. Your real choices are, "take it or leave it." So if seawater is better than nothing then seawater it is indeed.
What is it the glucose id doing? That's really interesting and it's got me curious :)
@@danielculver2209 ok you have the semi right idea but that’s not really how any of it works and I don’t blame you cause even my biology degree doesn’t go into as much detail if you really want to know you’d have to go to mes school.
First of all let’s clear something up which could save your life. If you ever stranded at sea don’t drink sea water for two reasons, salt indeed absorbs water so a very salty water that you drink will dehydrate you but it’s also full of micro organisms that will 100% make you sick causing diarrhea making you dehydrated even faster. Urine is even a better short term. Now drinking and IV is not the same, if you IV straight sea water two things will kill you an infection from then nasty microorganisms that live in there and salt dosage.
See your body needs to have a careful balance of ions such as potassium, sodium and others which to spare you the chemistry we will simplify and call them salt (it’s more complex than that but to avoid confusion it’s fine) same way you body needs to be at a certain temperature to function properly, too low or too high not good and the closer to the extremes the more dire. Your colon in the case of an IV has nothing to do here, the point of an IV is to by pass the colon and go straight in your blood hence why if you severely dehydrated you given saline by IV but it’s very carefully dosed otherwise it would kill you. By doing that we can also add vitamins you might need, etc but like with anything too little will do little and too much you’ll OD.
The reason why you need it with glucose is because your cells need certain ions to do other jobs, water for example can pass in and out cell membranes passively by osmosis, high concentrations go to low concentration.
Blood has a high concentration of water so when a cell needs it because it has a low concentration then osmosis happens and it gets a refill (google osmosis for more detail in that but it’s as simple as that really).
That’s called passive transport but ions like sodium can’t do that, they too big to fro through the cell membrane as per design so there are special proteins attached that facilitates the transfer, this is called active transport and it requires a bunch of chemical reactions I won’t get into (either google or enroll in a biology intro class to really understand it cause there’s lots going on) and to do that it needs energy or ATP. To make ATP you need glucose which you get from different sugars but that’s the easiest for your cells to break into ATP.
So glucose is not necessary unless you extremely dehydrated but if you need an IV then yeah you need the glucose to. Naturally when you eat you get the glucose so that whole process is balanced. So from that you can understand having way too much water or having way too much of any of the salts can disturb this carefully balanced system and cause problems. Little too much little problems and way too much big problems aka lethal.
With most things dosage related it’s about balance, eat too much salt you dehydrate your cells, don’t eat enough and they can’t facilitate nutrients from your blood to the cell. Don’t drink enough water and your blood lacks water and gets too thick, drink way too much water your cells fill up with water and pop.
So it’s case by case, if you somehow down 10L of water in one sitting you will die. Biology is similar to chemistry where it’s all about keeping the system balanced to achieve the designed outcome. Hope this helps, there’s a channel called In a Nutshell that covers topics like this with great animation and good info. I love watching it while I’m seshing and they cover a wide variety of topics from the human body to outer space and they provide their bibliography so you can go read their sources. It’s really cool
They said at the start that the seawater was filtered and sterilized first @@dreammaker9642

The feather star is one of my fave creatures! I had one in a tank some time ago... Loved watching it swim.
That is awesome all this time I thought crinoids were all left behind in the Devonian! They are still with us! Now someone needs to discover trilobites still exist somewhere.
It wouldn't surprise me if they do. I think they found brachiopods alive somewhere.
Sea Lilies walked so Feather Stars could swim.
Feather stars moving look like ballet dancers to me - beautiful!

The editing could use some work, but Hank is always a diamond in every science channel.
Ok this is weird. I have been subscribed to this channel with the bell on since day 1 of its first launch, this is the only notification I have gotten for this channel ever and I just looked at your library of video's. To say I'm quite miffed is an understatement.
I have found everything that Hank works on our with to be informed, informative and just enjoyable to watch. Even if Hank isn't the one giving the presentation. I have used Sci Show and PBS's RUclips channels to educate myself and many others over the years.
The videos are all a great jump off point to learn more about whatever the topic is that has peaked your interest. Honestly I think it was a PBS program on television (I'm way way older than the internet) that set me on my career path to becoming a Geologist. For me it's been worth the little time and money invested into watching and supporting programs like these because I am able to share the knowledge. And who knows maybe I will share the information in this video or share the video and someone is inspired to become a marine biologist.
The crux of what is angering me about not getting notifications is not a RUclips algorithm issue but a Canadian government issue. I know that because this is an educational program presented by Americans and not Canadians my government has been blocking the notifications, attempting to force me to watch Canadian made content.
Well our scientific programs are not known for their accuracy. Particularly since we basically have to give airtime to things that aren't true. Flat Earth theories, ancient aliens, etc.
I cataloged the Springer collection at the Smithsonian and my duties were exclusively crinoids! Many of the items you have pictures of I put into our excel database. I only worked on sea lilies and got so good at identifying them I was allowed to make corrections to identifications despite just being a volunteer (I always consulted with a professional first before making an official determination). Love to see these guys get featured because they are truly remarkable creatures!
This 🌟 is weird as heck and truly bizarre
3:35 Mom used to say "Exactly the same only different." It's surprising how often that's true.
I knew crinoids were still around, but I didn't know any of the extant species were sealilies
Both stalked and non stalked crinoids are the solo branch of a line that was very diverse in looks from Ordovician up to Mississippi period.
I think the Closest animal I can compare these Feather Stars are Biblical Accurate Angels
Samuel Z. Arkoff and American International Pictures really missed out on the ultimate nightmare creature.
"Mommy, I think that sea flower just moved."
"Honey... I don't think that's a flower..."
Seriously though, crinoids are amazing.
Featherstars decided to contribute to the slickback dance trend
I could see sea urchins as being the reason that feather stars evolved, if the shallow, warm-water environments had previously been occupied by stalked varieties. That would depend on when the sea urchins evolved.
Predation by ancient urchins. That's an album title.
Cool video. 2:31 They're both in the Kingdom Animalia, so corals are also animals.
Thank you for beating me to it! Searched for this comment to see whether I had to say it!

I absolutely hate it. They didn't mention if it had defenses or not. It looks very dangerous.
I saw many feather stars on shore after a storm
"Im bleeding out!"
Bro, you are swimming in your blood
2:24 You contrast crinoids being animals with coral as if corals aren't animals, but corals are animals too...
Biblically accurate sea urchin
0:32 Hmm I think it would be helpful to maybe do voice-overs of incorrect information. Visually impaired people might not see the corrections in the video itself.
I agree
TFW you learn for the first time that you share a planet with underwater animal trees
And the big question everyone still has, how to keep feather stars alive and thriving in an captive environment.
Woooooo! Someone else talking about how rad sea stars are!!!!!!! Let's goooo!
Fun fact: pycnopodia is a sea star which can get to the size of a manhole cover and has way too many arms (15-20+).
Feather stars are so beautiful! Ahhh I'm so happy someone is talking about these guys! They're so rad! The fact that they use the hydraulics of the sea water to move their little tube feet is so cool.
Can I just say that I LOVE your jacket? Seriously, where the hell did you get that?

While reading the book 'Hidden Potential', I learned about Sea Sponges. They are the earliest, primitive animals, even though they look like plants. They have a skeleton, mouth, filter water, purify water from toxins/bacteria, and sneeze out mucus through their pores. Please do a deep dive on Sea Sponges! Sea sponges are part of an artists equipment adding texture and are a shortcut to simulating foliage in watercolor paintings.
I love this video :D (and thanks for, rather than remaking a favorite, you added the new stuff - great approach I've never seen that!)
The thumbnail for this video implies that our beloved host is one of these ancient creatures and, in fact, NOT the one that can swim.
Way to knock a creature down.
What is really interesting is that hydro vascular systems aren’t that uncommon. Many of the relatives of the feather star (urchins, sea stars, etc) also use water in place of blood!
Imagine basically a plant evoling to run away from predators 💀
Not "basically a plant", though. (Meanwhile, *_actual_* plants have evolved to *_be_* predators, so...)
What a great video! I’ve never seen feather stars moving. It’s gorgeous! Thank you.
Sounds like an insult......"That dude at the end of the block is a real Crinoid!"
My brain can't handle the sheer amount of cuts, cutaways, different voices, pictures, tones.
I think i read somewhere that crinoids was the inspiration to the facehugger in the alien movie.
Anything that loves in the abyss is fuel for nightmares 😂 it’s a trend that evolution cares not for your mental health. Don’t even have to go that far, if you want to make a therapist rich Google foal slippers 😂
