A emu egg (left) next to a cassowary egg (right). They are some of the largest bird eggs on the planet.

Collecting the cassowary eggs more often results in death

Hands off my eggs.

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.
I didn't know ostriches lived that long.
- I didn't even know she was sick
Shape and color are very different. I assume that's just normal for the different species, but this one looks almost like it might be transparent. Is that an arm sticking out of the top? How does the size compare to the green ones? Does it rot, or is it just the shell?
- It’s a solid milky white colour with some large dimples throughout it. Only really transparent with a strong light source.
  It’s the sleeve of my jumper, as for size it’s about 10-15% bigger than en emus from memory, mostly wider than taller.

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?
- 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.
Tell me about whale eggs? 😯

Even the land whale?

Hmmm...

First thought
That's some strange looking pears, that's for sure.

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

These ones must be hard-boiled.

They are also single frigging cells. Yet, they have nothing on the largest unicellular organisms, size-wise.

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/

Someone gave me an emu egg years ago, and I proudly displayed it for a long time. Then I got cats, and realized quickly that I should put it away.

That green look so green you could probably use the egg as a green screen

Therefore an eggscreen

I think he got them from a guy named Sam.
But I want to know-- will be eat them on a train?

How do you even get your hands on a cassowary egg and not die a horrible death. Emu’s are chill as long as you’re a guy

The bright one has a natural QR code

Now we need a Kiwi egg and a diagram of each animal next to each other. Absolute legends of a flightless bird.

Which one tastes the best?

That cassowary egg is moving

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.

They both look like avocados to me
