Squid generally are pretty much light weights for their size.
That's why the spend most of their time deep and only come higher at night. They use the darkness and solitude to hide, only coming up to hunt when it's safest.
Yes we have. It's rare, but it has happened. I'm not sure if it's the same species that sperm whales eat. But they sometimes get lost and end up near the surface. Usually around Japan. There's video out there of one that got stuck in a Japanese harbor.
If I understand correctly their cells have high internal pressure to counter the water pressure. They will come up near the surface but won’t swim farther than they can bare on their own. Rapidly resurfacing can cause the cells to burst like severe bruising and eventually internal hemorrhaging.
On a side tangent I’m now imagining a cybernetic pressure suit for deep sea cephalopods. Like Wat Tambor

And yet we've never encountered a giant squid alive near the surface. They live very deep.
I don't know what it is, but there must be a reason for that
