What does water "feel" like at that depth? There is a lot of weight felt I guess from the pressure, but is it thicker to swim through in some sense?

I’m wondering the same thing. You can see their fins flopping around as if it’s regular depths

Water is incompressible, so I think it should behave similarly. Even viscosity remains within a few precent [1] (Mariana Trench is around 100 MPa)

#24Earlier quoted context omitted.
Fun fact: the (in)famous Icelandic "rotted shark" (hákarl) food is rotted/fermented in order to remove the toxic TMAO (and urea): https://en.wikipedia.org/wiki/H%C3%A1karl
>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.

#25DSSV 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…

Ah, thought you were talking about Tangents, the Greg Bear short story collection.
Re: Deepest fish ever caught on camera off Japan
#27If you ever wondered how they survive the pressure, from wikipedia: TMAO (Trimethylamine N-oxide) is found in the tissues of marine crustaceans and marine fish, where it prevents water pressure from distorting proteins and thus killing the animal. The concentration of TMAO increases with the depth at which the animal lives; TMAO is found in high concentrations in the deepest-living described fish species, Pseudolipar…

So what’s natto’s excuse?

There's definitely an MSV Pressure Drop on that page, under the list of ships in Hydrogen Sonata. :)

#29> At 8km down, they are experiencing more than 80 megapascals, or 800 times the pressure at the ocean surface. Is this somewhat a coincidence or is this the beauty of the metric system?
Those factors of 10 don't really look so nice if you use e.g. the binary number system.

The Incredibly Tangential Information must be another Culture ship?
