This Creature Is Older Than The Concept of Blood 

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.

does this mean he’ll be back 🫣

​​@@rhiannonm8132 I mean the ocean is real big, so maybe? Not on purpose though. The feather star's dad is out for milk.

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.

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.

Absolutely underated comment. Literally made me laugh out loud.

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 😂

I was looking for this comment 😂

We will find out that they have thousands of tiny eyes covering their arms and that they are technically immortal.

Probably because it’s a lot harder to filter feed from the air.

I don't know the name of the phobia but im sure i have it because of what u just made me think of these things thanks 😂😂

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.

For God and everyone 😂😅

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.

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 😂

They usually say don't be afraid when they show up in their true form, so yeah. This explains it quite well tbh.

Science papers are often just long passive aggressive arguments going “nuh-uh!” At some other scientist.

@@weirdredpanda Could be some Batesian mimicry, but I haven't found anything mentioning it

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
