Re: Fish found at 4.8 miles down.
That's just incredible. They appear so soft and bendy, just like normal fish at the surface, yet the pressure will be astronomical. I see in the article that the fish make physiological adjustments for the pressure at the molecular level.
I'm not sure if the fish would explode or turn inside out if depressurised quickly.

Re: Fish found at 4.8 miles down.
Imagine having caught one of those and then you proceed to fry it for your supper. Booooom!! It'll take away half the kitchen!

I'm not sure if the fish would explode or turn inside out if depressurised quickly. Just as when divers can work at depth if they're pressurised 'inside', the same must apply to the fish. Otoh if their internal pressure was that at the surface they'd by crushed flat by the pressure.

Re: Fish found at 4.8 miles down.
beaufort:
The article has a few flaws as far as i can see.
1. It doesnt tell us whether the fish is worth eating or the best way to cook it.
2. It doesnt tell us what bait it can be caught on.
3. It doesnt tell us how long it would take to reel in the 5miles of line should we discover what bait they like and actually catch one

Re: Fish found at 4.8 miles down.
Pingo:It just shows how much species can withstand. If that were true we would not need to trawl the depths we could just catch all the fish we need from the continental shelves. For starters look up on the history of the Grands Banks of Newfoundland. You can't catch what isn't there anymore.

Re: Fish found at 4.8 miles down.
Marigold:
I was trying to find out what the pressure is down there - and came across a much more useful analogy than SI units - "equivalent to 1600 elephants on the roof of a Mini" 
And to Pingo - it's not 'withstanding' if you're physiologically and anatomically designed for those conditions, just plain living.
A bit like becoming a greenhouse worker, really. I find myself trying to adapt to the horrendous conditions around me and then I wonder how the hell I've been able to put up with it for the past 16 years! 
Sorry, it's been one of those days at work today. I'll sit quietly in my little corner.

It's a good analogy Ian - A tomato thrives in there, its 'design' is in harmony with that environment - you poor Ian, can only withstand 
Found some more interesting facts - the bottom temperature was 1.905°C, the bottom salinity was 34.68ppt and the exact pressure exerted on the lander at the bottom was 7900dbar (1 dbar = 1.4503774 psi)

Thanks for the interesting facts Chrissie getting on for 11,500 psi phenomenal pressure!
