Deepest living fish

[LordGrover]

Weirdy snail fish filmed at 8,143 metres which is pretty much the limit for living creatures.
On what does it feed?

Article and video.

5 miles down...boggles the mind.

Could be a detritivore - ie eats the tiny bits of organic crud that come down from above.

Hows can something so delicate withstand such high pressure and if you brought up to the surface would it expand

I guess that would make sense

What's the story about the amphipod?

What's the evolutionary story? How do you end up evolving to live at 5 miles down. Assume you start living in the shallows and then keep finding evolutionary advantages of going a bit deeper every so many generations.

Why 5 miles? What forced it deeper at 4 miles, and 3?

In terms of evolution, could it be similar to the bar headed geese that have been observed flying over Everest? The theory there is that their migration route existed before the Himalayas, so as the mountains grew, the geese simply evolved to fly higher. Could deep level creatures be the same in reverse? They may well have existed in shallower waters which became deeper over geological time, rather than actually seeking them out.

Doesn't connect. Assuming the geological assumptions to be correct, the geese HAD to fly higher to get over the mountains, but the fish didn't HAVE to swim lower just because the sea got deeper. More likely they were forced deeper by enemies, and going deeper gave them protection.

Ahh, fantastic. Saves me from thinking.
