Sperm whale lungs collapse during their dive
Wouldn’t that be true of any whale’s lungs?
Humans’ lungs get smaller when they dive.
Or do you mean they get flat as a pancake?
Looks like you're right it's not just the sperm whale and the ribcage is flexible in whales so it can collapse
They dive crazy deep, third deepest in the world so I'm not sure if other whales' lungs can outright collapse rather than just flex
