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?

[–] CuddlyCassowary@lemmy.world 35 points 1 week ago (1 children)

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

[–] SpaceNoodle@lemmy.world 7 points 1 week ago (1 children)

Oh. I thought we were gonna make more eggs

Lego my egg-o

My 30 year old ostrich egg.

[–] SmackemWittadic@lemmy.world 41 points 1 week 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

[–] ZeffSyde@lemmy.world 23 points 1 week ago

That's one hell of a gestation period.

[–] ProvableGecko@lemmy.world 7 points 1 week ago (1 children)

I didn't know ostriches lived that long.

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?

[–] CheeseNoodle@lemmy.world 29 points 1 week ago (1 children)

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

[–] dependencyinjection@discuss.tchncs.de 42 points 1 week 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?

[–] dependencyinjection@discuss.tchncs.de 6 points 1 week ago* (last edited 1 week 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.

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

[–] ickplant@lemmy.world 18 points 1 week ago

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

[–] Prime_Minister_Keyes@lemm.ee 24 points 1 week ago* (last edited 1 week ago) (1 children)

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

[–] smee@poeng.link 8 points 1 week ago (1 children)

wiki

Good grief, just tell us the size. I skimmed the article and is none the wiser.

[–] Jakeroxs@sh.itjust.works 3 points 1 week 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

[–] betterdeadthanreddit@lemmy.world 50 points 1 week ago (1 children)

These ones must be hard-boiled.

Used to be my favorite t-shirt...

[–] barneypiccolo@lemm.ee 13 points 1 week 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.

[–] duhbasser@lemm.ee 11 points 1 week 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

[–] lunachocken@lemm.ee 11 points 1 week ago (2 children)

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

Therefore an eggscreen

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.

That cassowary egg is moving
