Now we need a Kiwi egg and a diagram of each animal next to each other. Absolute legends of a flightless bird.
Mildly Interesting
This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.
Rip whoever birthed the sea urchin.
They are also single frigging cells. Yet, they have nothing on the largest unicellular organisms, size-wise.
wiki
Good grief, just tell us the size. I skimmed the article and is none the wiser.
The biggest single-celled organism in the world is structured in the same way: an aquatic alga called Caulerpa taxifolia, which can grow to 30cm long. https://www.australiangeographic.com.au/blogs/creatura-blog/2019/04/this-bizarre-bubble-creature-is-a-single-living-cell/
Put them back mf
The forest was burning, so he rescued them. Now he will put them back, lovingly, on the stove for breakfast for him and his five children.
Those poor eggs.
Out of the fire,
and into the frying pan.
That green look so green you could probably use the egg as a green screen
Therefore an eggscreen
Hmmm...
That's some strange looking pears, that's for sure.
First thought
Fun fact, ostrich eggs are nearing The largest land eggs can physically get, so even the dinosaurs didn't have much bigger eggs.
What's the limiting factor?
If I had to guess it'd be the ability for oxygen to diffuse through the shell and reach the embryo?
I got curious and your assumption is correct for one of the limiting factors.
Here is what I found:
- The shell must be strong enough to support the egg’s weight and protect the embryo, but thin enough for the chick to break through when hatching.
- As size increases, the weight grows cubically (volume), but shell strength only increases quadratically (surface area), so there’s a point where the shell would have to be too thick to hatch from.
- The distance from the shell to the center increases.
- Oxygen diffusion becomes inefficient, and the embryo could suffocate.
- Larger eggs are harder to keep at a uniform temperature.
- Birds incubating the eggs would need to generate and distribute more heat, which is physically demanding.
What's your sources? Begging your pardon, that looks like a perfectly standard GPT answer.
I think point two may be wrong. The strength of a shell should be proportional to its thickness, which would scale linearly with its size (assuming the shell got thicker in proportion to the size). There's definitely a point where a self supporting egg requires very thick shells like you said, but the scaling law you gave uses the wrong change.
Appreciate the share, that's awesome info
I never even considered that but it makes total sense. Thanks for the great post.

Any info on why both are GREEN? That's unexpected. Camouflage, maybe?
I am not an eggspert but after a quick search it seems many bird eggs are green in colour due to a pigment called biliverdin.
Interestingly verde is green in Spanish.
A lot of biological and other scientific terms are actually Latin or some mix of it. Bili means "Bile". Sources say "verd" in this case comes from French verd an old way to say green (Modern: vert/verte), but in any case the French words still derive from Latin viridis.
Spanish, French, Italian, Portuguese, Romanian, Catalan, and a few other minor languages are all descendants of Latin collectively called the Romance Languages. Speakers of one can often understand a lot of any other of the languages or Latin. Not completely mind you, but enough to get some meaning. Spanish speakers can understand a lot of written Portuguese (but not so much spoken due to pronunciation differences), Italian and Spanish speakers can almost have a conversation spoken or written. Portuguese/Italian/Spanish speakers will have a harder time with French though, they will recognize many written words but not enough to really call it totally understandable, and almost nothing spoken. Etc, etc.
My 30 year old ostrich egg.
I'm no Ostrich expert, but I think that egg is defective if it has yet to hatch in 30 years.
You should get a refund
That's one hell of a gestation period.
Collecting the cassowary eggs more often results in death
Hands off my eggs.
Or what, you'll cuddle me?
Lego my egg-o

I too don't know my left from right but the dark green is an emu egg
Turns out you are right! I was just copying the caption, but I’ll fix it.
Wait till you see the Kiwi egg
