I too vomit while standing up at my full height.

[–] [email protected] 48 points 4 months ago (3 children)

Ye, they would probably bow down to vomit. Would be interesting to see how giraffes do it.

[–] [email protected] 48 points 4 months ago

Puking giraffes, sounds like a band name

[–] [email protected] 18 points 4 months ago

I found a youtube video explaining that giraffes have four stomachs. They vomit from the forth to the second or first, and very rarely does it come up. https://youtu.be/7EXnc8SXWV8?t=70

Owls (owl pellets) or even snakes and lizards would probs be more accurate imo

That's an impressive superpower.
Looking harmless and then suddenly violently puke like a fire hose stream on some poor bankrobbers or something.
I bet that it wouldn't need to be some strong acid to be an effective repellent.

I call it "stand and deliver"

Are we sure they could vomit?

[–] [email protected] 27 points 4 months ago (1 children)

not sure, but 2 seconds is thinking about living animals tells us that that would probably bend over first.

[–] [email protected] 12 points 4 months ago

And 2 more seconds and you start wondering how many pints it would take.

Maybe not projectile vomit but they absolutely could reverse peristalsis just like any vertebrate. Giraffes chew their cud while upright after all. Peristalsis is agnostic to how high it's pumping, since there is no functional loss in strength.

AFAIK Horses cannot vomit, and I also was told that mice and rats cannot vomit.

[–] [email protected] 7 points 4 months ago (1 children)

What I'm describing isn't actual vomiting either, but more like regurgitating. Rodents can do that, though horses can't (because they can't even belch, they've got a one way valve).

Ruminants like sheep and giraffes also don't externally vomit but they do internally vomit which makes stuff change chambers in their stomach.

[–] [email protected] 7 points 4 months ago (1 children)

Somehow the last part seems worse than vomiting. I know it isn't, but eeww.

[–] [email protected] 2 points 4 months ago

Internal vomitting is when it comes out of your nose?

[–] [email protected] 3 points 4 months ago (1 children)

A question I never thought I’d want to have the answer to.

Do birds vomit?

[–] [email protected] 5 points 4 months ago* (last edited 4 months ago)

They feed their young through regurgitation so they do have the ability! Now can it be projected at a distance? Hopefully someone can inform us lol.

[–] [email protected] 35 points 4 months ago (1 children)

What's even scarier is that it used that amount of strength to bring the vomit up

[–] [email protected] 7 points 4 months ago

"Today, we discovered the first time 'Eastbound and Down' was heard, coming from an unlikely place..."

Is friction really negligible here?

[–] [email protected] 24 points 4 months ago (2 children)

It's probably pretty important. This paper on the terminal velocity of water droplets shows an upper limit of around 10m/s. And terminal velocity is reached in under 6m.

[–] [email protected] 2 points 4 months ago

Thank you for looking it up.

[–] [email protected] 1 points 4 months ago

Even at 10m/s, thats 41kN of force.

[–] [email protected] 5 points 4 months ago (1 children)

Honestly not that bad, tbh. You can easily beat those numbers with a hit from a car.

[–] [email protected] 6 points 4 months ago (2 children)

Not during the Jurassic period, they didn't have cars.

[–] [email protected] 5 points 4 months ago

Just commenting on the deadliness of 68,600 N in terms of a modern equivalent. People survive cars, raptors might survive vomit.

Fred Flintstone begs to differ

[–] [email protected] 4 points 4 months ago (4 children)

But they were herbivores..? The image shows bones in there

[–] [email protected] 25 points 4 months ago

Those are the bones of its victims. Raptors dread the vom bomb

[–] [email protected] 19 points 4 months ago

I was wondering if they were implying the force would be enough to kill smaller dinosaurs?

[–] [email protected] 8 points 4 months ago (1 children)

The idea is that the impact would have killed a little dromaeosaur

[–] [email protected] 2 points 4 months ago (1 children)

Maybe, but it's weird they drew it as nothing left but bones though

[–] [email protected] 8 points 4 months ago (1 children)

Well someone cropped the part of this image where this maths experiment was inspired by trying to figure out how a small dinosaur died in a stranger crater.

That image is an outline of the fossil millions of years later, not a drawing of puke containing bones or a dinosaur getting instantly defleshed

[–] [email protected] 1 points 4 months ago

Ahh that makes sense

[–] [email protected] 6 points 4 months ago

Clearly they threw the bones up since they're not meant to eat them

[–] [email protected] 4 points 4 months ago

Thats also roughly the amount of force the Brachiosaurus would need to exert with just stomach and throat muscles to get the vomit up that high. I think they wouldn't be able to do that and would constantly get heart burn in their 30' esophagus.

Much more likely is that they lowered their heads in humiliation and let the vomit slide all that way out.
