It's a whole new modality, and it seems we do not have output devices (yet)

I wish I could do that, too. But I'm suffering from Paruresis aka Shy Bladder Syndrome. Really weird condition. Mostly just a mild nuisance at worst. But there is this phenomenon where you have to pee when scuba diving even if you don't drink more than absolutely necessary. Twice I was stuck on a speed boat bumping up and down while my bladder was full to the brim - that is very painful ... everybody just merrily spreading their fountains of pee off the deck. Anyone here successfully made peace with their inner dolphin?

That depth pressure has interesting effects on the body. I think it literally forces molecules of water from the body to the bladder. Sorry to hear you have mix of those 2 situations, dehydratation aint the best feeling but risking of rupturing the bladder is definitely worse

Interesting theory - but wouldn't there have to be some gas involved (bubbles, cavities) as water isn't impacted by pressure (at least not at a level experienced while scuba diving)? The pressure though will certainly impact the (pressure) sensor in the bladder signalling that it is full. But my impression (no pun intended) is - as you also suggest - that the bladder actually fills up faster due to some physical / physiological effects while diving. Even at the surface at some point the lower part of the belly is palpably tense. My hunch would be that something speeds up reverse osmosis (mineral/colloidal concentration of two regions separated by a membrane evening out by water moving into the region with higher concentration); as I'd assume that the already present urine has much higher concentration in salts and proteins compared to the surrounding tissue.
I just had the idea that it might be due to water entering the body and blood stream through the skin (by means of reverse osmosis). The kidneys then excrete the excess water into the bladder.

It speculates that peeing in the air may signal the dolphin's health or social status. It must suck to be a loser dolphin who can't signal lest he get ostracized further. Nature is cruel, and this practice, if true, I would imagine, would speed up natural selection. Kind of like if humans would voluntarily share their wealth status. Wait, I guess we do do that.

"Peeing in public again, Billy? Can you please stop that? It's disgusting."
