Fish use gills, which extracts oxygen from the water. Amphibians and whales breath oxygen, whales can hold their breath for hours at a time, explaining how sperm whales can hunt at great depths for periods of time.
Whales survive by eating krill.
They produce lots of blubber to protect themselves from the cold and the extreme pressure at lower depths. Jellyfish drift, whales swim. This is partially true but the main reason whales have a lot of blubber is a question of buoyancy. Fat is much less dense than muscle and bone and without it the whales would sink very fast.

Whales are sea animals and Antarctica is a continent. Whales survive in the Southern Ocean -- which surrounds Antarctica -- because it is their natural habitat when the ocean is free of ice.

Dosidicus gigas spend 95% of their time at depths too deep to be safe for divers. They can only survive short periods when removed from these depths.

Whales breathe with lungs. Breathing helps them survive.
