Missing Sub

A hard cylinder that wasn't made to go to that depth is a recipe for disaster. I can't answer as to the squid but the whale is taking a limited amount of air with it so I would think it would be thrusting to get to the squid. Squids and whales are made of mostly meat but the pressure doesn't seem to affect them. There are fish, shrimp, worms and probably hundreds of other creatures down there also that aren't effected.

I'm trying to figure out where you're going with this? Humans are not built for those depths, they do not have the ability to self regulate their internal pressure.

Here is what 300ft will do to a human when pressure is lost, think of what 12000 will do. It would be much more instantaneous and graphic.

I understand humans can't handle deep sea water pressure but why can a whale handle it? They are also mammals. You can use size as a reason but then why can worms and fish handle the pressure? How do fish manage to pull oxygen out of water so tightly packed it would be like breathing cement and thrive? They've had many thousand years to figure it out but it seems like they are from another world.

I think "pressure differential" is the key here. An animal swimming at those depths has little to no pressure differential whereas a vessel from the surface has a massive differential from surface to 1,100 meters or whatever the depth was.

This doctor gives a good explanation of why whales are able to dive to extreme depths and what would happen to the human body at those depths outside of a vessel.
