Eli5: why not bring deep sea fish to the surface in a pressurized container?

449 views

A lot of deep see fish die and/or severely deform when they’re brought to the surface for study. Why not put them in a pressurized container so they can be preserved in a way that leaves them the same?

They do that sometimes. I’ve seen a deep sea exhibit in a public aquarium where the tank was pressurized. It’s way harder, and therefore way more expensive and less common.
