So in essence, pearls are the body reacting to an invasive material by coating with a thick substance that solidifies around it. In other words, pearls are pretty balls of hard snot. Good to know!
It's worth noting that the vast majority of pearls that form naturally are not round, and most are not gemstone quality, either. Prior to the development cultured pearls, gemstone quality pearls were extremely rare and valuable, so much so that Seneca, writing of the excesses of 1st century Rome, griped about women who wore three-pearl earrings: "This womanish folly is not exaggerated enough for the men of our time, unless they hang two or three estates upon each ear."
@@GameFuMaster Really? I guess that just means women are braver than men, since we can handle the pain of a piercing and men cower because it's "womanish".
I come to learn about pearls but am more amazed about how an oyster came to be. I’m so fascinated to learn that it started out as a larvae, forming a shell around itself (the idea of a tiny bare oyster flesh just floating around never occurred to me before). It makes so much sense. That’s why the flesh is always joined with the shell when we eat any shellfish! Thank you TedEd for reawakening my wonders to life.
1. Calcium carbonate is common in the ocean. 2. Oysters build layers by filtering calcium and carbonate in the sea water. 3. With special proteins, there are 2 variants of crystal structure produced from this - calcite (external shell) and aragonite (internal layer), which have different qualities. Calcite is more stable as compared to aragonite, and is less prone to dissolving. 4. Nacre (the pearl) is formed as a crystalline structure eventually. This stronger and more versatile form of aragonite is formed when hexagonal bricks of proteins and aragonite are stacked so uniformly that light bounces in a cascade of rainbows.
I am 37 this year and am just starting to be curious of the lifecycle of an oyster and how it produces magnificent pearls. 😂 thanks a bunch Ted-ed for always being a great lecturer ❤
it used to be so confusing to me that people prized pearls higher than the shells when i learned that they were the same material. I still find it slightly weird, but I understand people prefer certain shapes now.
The same material in different shapes or forms can have very different values. An example off the top of my head is wood. You can have a plank of wood, which sure is nice. But you can also have a figure of that same material, which will be worth a lot more even though it's the same material.
Well, I don't consider it a wild guess if you assume that it sometimes starts with a grain of sand, 'cause maybe they can't differentiate that from something else. Just a thought...🤷♂
I mean I just love the way the animation is being presented. Specifically the inside ocean scenery, giving the water vibration ads out of the world experience to it.
The human body does this. It calcifies foreign things in the body. A "stone baby" is a incredibly rare pregnancy that dies inside and never expelled, the body covers it in calcium and it becomes a stone. Usually found years and years later. Look up pictures, its pretty amazing, sad but amazing...
Great knowledge delivered to public. Very nice experience while searching for the formation of a pearl. I heared a myth in my childhood that when first rain drop enters a sea shell it converted to a pearl. But those all are myths anyway
Although it looks easy but it takes sometimes years for them to make one pearl . As said 'everything can cause irritation' and hence not every pearl is round and beautiful . Hence, pearls are rare, south sea pearls are one of the most expensive ones.
A little confused at 1:15, I thought that adding CO2 to the atmosphere and that being dissolved into the ocean actually created carbonic acid which attacks CaCO3 in the ocean and makes it harder to build shells
There are a few steps to the chemical reactions that occur. Carbonic acid then dissolves to make a proton and bicarbonate. That bicarbonate then further dissolves to make another proton and carbonate. These different chemical components all co-exist and the proportions of each depend on the pH. "Ocean acidification" as a term isn't really accurate to describe what is occurring. Instead, what is technically happening is that the ocean is becoming less alkaline, which means that the increasing amount of CO2 going into it now, is removing the bicarbonate and carbonate that are needed for shell-forming. Does that make sense?
Yes I studied all comments of this vedio according to organic chemistry he's one word is true because in our phushto culture a great waliullah and point he tolled in his rubbish ,,,hard yo saaski ghawher ne shu pe sadaf ki balance knowledge u can take from his books but is true pearls are made from rain drop ,it is 40/ years I am surching for original sea pearl in market most of artificial and a few with England queen and some of in digest stories.
I wonder if the Kings and Queens that wore pearls ever thought of them as results of intrusions. As defense mechanisms…it reminds me of Elizabeth I who as some historians say wore such poisonous make up that irritated and ate her skin (and might have killed her)…beauty always find some correlation with pain and irritation.
pearl and nacre is a relatively recent discovery. The last 100 years type of deal, so likely old heirs didn't know or didn't think of this possibility. Also, to my understanding, it was not uncommon for members of a royal court, bourgeois, or high house, to experiment with chemical substances to produce make-up. It was the norm for many parts of europe.
So the obvious question is...why dont they just make the outter layer of their shell out of Nacre( or whatever its called) if it is the strongest material they produce? Probably takes too long or uses too much energy im assuming.
Pearl. Broca's area, or the Broca area is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with functions linked to speech production.
Irritant is an incorrect term. It DOES NOT form pearls, after all mineral capable epithelial cells do not appear spontaneously at an affected area. Perforation of the outer pallial mantle is the proper term.
The answer to the question comes at the last 30 seconds of the vid. Also, he said it's just a leading theory, so I guess we don't actually know how they are made.
Probably years. I never felt comfortable wearing them. Beautiful but some people think it's when an invader injures them. I never thought of it this way.
So in essence, pearls are the body reacting to an invasive material by coating with a thick substance that solidifies around it. In other words, pearls are pretty balls of hard snot. Good to know!
I’d argue that they might be zits ;)
A perfect layman's terms
Didn't you hear this is just the leading theory? So there's nothing to know, but to believe.
I do think there was too much talk over something that can be greatly simplified and shorter
So my mucus is a small amount of undeveloped pearls?
One day someone will make a horror movie based on giant oysters turning humans into pearls. And I'll watch every second of it.
At least they die pretty 😂
I wouldn't be surprised at all if Japan did that, since they already have a movie where people turn into snails
🥶😮

These animations look like they are created by people who love what they're doing. The narrations too
Woah I actually always wondered how but always forgot to ask thanks Ted ed for always giving us interesting facts and pieces of knowledge
this is so interesting, I grew up in the persian gulf, i dived for pearls as part of my tribal heritage using traditional boats and tools

Literally investigating nacre and shells for my masters so this ted video was a pleasant coincidence
This was one of the most impressive animation styles TED-ED has ever deployed. Hats off to the animator 👏

hats off to the illustrator /animator of this video 💯🙌
I mean I just love the way the animation is being presented. Specifically the inside ocean scenery, giving the water vibration ads out of the world experience to it.
The animation on this one is impeccable.
The CO3 in the water which helps build the shell, also degrades the shells when in abundance (carbonic acid).

Same with boogers. That's just a foreign invader that's been encased in mucus and later solidified. Pearls are essentially an oyster's boogers.

The sound of the oyster closing like a giant door. Awesome
The production value in his video is just 😮❤

Our minds are like oysters, we earn pearls as knowledge
So many oysters, so few pearls ❤
So you see, when a Mommy Clam and a Daddy Clam love eachother very much...
…they make a smaller clam.
There are pearl farms in different parts of the world, so it seems to be a very solid theory if the results can be reproduced so consistently.
What a pearl this video was!

How would they react to the irritation caused by intrusive sand if they have no central nervous system?
So basically pearls are deep sea kidney stones

WHAT DID HE SAY AT 3:24????
I was always curious about this!
3:24 I had to do an auditory double take because of the way he said "nacre" 🤣🤣
