Incredible.

Why don’t these deep sea creatures just expand when they are out of the pressurised depths?

Because they are full of fluids not gas. Gas expands, fluids do not (significantly)

Gas is a fluid.

I’m sure you meant “liquid” though.

They can change a lot though; blobfishes only look like blobs at the surface, they look like normal fish under the pressure they are used to.

Thanks DD 🙂

Incredible stuff.

looks like one of my attempts at poaching an egg 🙂
