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.

Collecting the cassowary eggs more often results in death

Or what, you'll cuddle me?

[–] [email protected] 35 points 2 months ago (1 children)

Yes, with my snuggle-talons. It’s a once in a lifetime experience.

Oh. I thought we were gonna make more eggs

My 30 year old ostrich egg.

[–] [email protected] 41 points 2 months ago

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.

First thought

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

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?

[–] [email protected] 29 points 2 months ago (1 children)

If I had to guess it'd be the ability for oxygen to diffuse through the shell and reach the embryo?

[–] [email protected] 42 points 2 months ago (6 children)

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.

Didn't think I would find egg facts so interesting... Cool!

Any info on why both are GREEN? That's unexpected. Camouflage, maybe?

[–] [email protected] 6 points 2 months ago* (last edited 2 months ago) (1 children)

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.

I too don't know my left from right but the dark green is an emu egg

[–] [email protected] 18 points 2 months ago

Turns out you are right! I was just copying the caption, but I’ll fix it.

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.

[–] [email protected] 3 points 2 months ago

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/

Wait till you see the Kiwi egg

[–] [email protected] 50 points 2 months ago (1 children)

These ones must be hard-boiled.

Used to be my favorite t-shirt...

[–] [email protected] 13 points 2 months ago

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.

[–] [email protected] 11 points 2 months ago

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

[–] [email protected] 11 points 2 months ago (2 children)

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

Therefore an eggscreen

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