DSSV Pressure Drop sounded like a Culture ship name to me so I looked that up. It's not, but the name of the DDSV, "Limiting Factor", is. Apparently they also named their utility boats after Culture ships. To those who don't know: "The Culture" is a... society(?) of godlike AI ships/minds from the series of SF books by Ian M. Banks. SpaceX named their landing barges after Culture ships too, the "Of Course I Still Lov…

This is the rare kind of comment that I can't relate to. I disagree with lots of things people say, sometimes diametrically - I might even consider some of them immoral, or feel angry about it. But I still can comprehend the frame of mind that can produce their point of view. But once in a while I can't even do that, even if the comment itself is not particularly wild.

I would imagine it is the extreme pressure. At that kind of depth you either need a really strong body and small surface area (tiny crustacean) or a gelatinous body where that doesn’t matter (snailfish). Those are probably disadvantageous at lower pressure environments. (I’m curious how molting would work at high pressures though, since the crustacean would lose its shell.) as far as blindness, there’s not really vis…

Creatures living in the deep simply equalize their internal and external pressures and don’t feel the pressure as some kind of weight they need to withstand. This is why when you bring them to the surface quickly they die from the sudden decrease in pressure. As to eyes bioluminescence is common in the deep and nothing would bother if nobody had eyes.

I'm sort of curious how they don't simply explode when you bring them to the surface.

It must be seriously exhausting to be bothered by such inconsequential things.

> Likewise, their approach to food - they are suction feeders and consume tiny crustaceans, of which there are many in trenches. I remember James Cameron’s dive and the main life pictured was crustaceans. I’ve also read they are a significant amount of life in underground aquifers [1] was crustaceans, which also had blind reptiles which also fed on crustaceans and had transparent skin similar to those snailfish. I’m…

Another commenter posted a link to a 2014 article that explains how the fish can survive so deep. https://www.bbc.com/news/science-environment-26423203 It says that fish use the TMAO protein to protect themselves from pressure. But other organisms use a combination of multiple proteins and that apparently lets them survive higher pressures. So it seems the fish would basically need to re-evolve how to handle pressure…

If they're born and live at that depth isn't the pressure equalized inside and outside of them?

The Incredibly Tangential Information must be another Culture ship?

GCV I'm Getting Fed Up sounds like a ship that was involved in more than a few skirmishes during the Idiran war.

>Chef Anthony Bourdain described fermented shark as "the single worst, most disgusting and terrible tasting thing" he had ever eaten.[2] Ok that’s saying something.

I tried a ~1x1cm cube of it when I was in Iceland... that assessment is pretty spot-on.

Did you keep it down? The pictures alone make it look very unappetizing, but I have to assume there is a significant aroma to the dish as well.

This is rounding. 8km would actually be 80304.7 kPa. So not as beautiful as you imagine.

I’m guessing the salinity of the water might affect the pressure?

Possibly offset by the volume of fish.

Those factors of 10 don't really look so nice if you use e.g. the binary number system.

Indeed. And the SI defining constants are downright ugly.

Yes, give me chains, barley corns and furlongs so that we have nice folksy constants.
