Comment on Another mystery solved.

If Godzilla’s biomatter under 1atm of pressure has a density close to water then being able to compress or expand an empty chamber inside his body by even just a tiny percentage of his ordinary overall volume could be the difference between floating at sea level or sinking to extreme depths.

First, let’s address the expansion of lungs, because you say “little air”, but in terms of volume, lungs are very big. On average, the volume of a human body is about 65 liters. When person fully exhales, the lung capacity is at about 1-1.5L; when expanded, it’s about 5-6L. Interpreted charitably, that’s roughly 8% percent of the entire human body volume. So realistically, expansion of the body by 8% is the difference between slowly sinking, and floating with the top of your skull (or roughly 1% of your body volume) peaking out of water.
Now, Godzilla, on the other hand, has like 80% of his body above water. Can you imagine, the amount of expansion that needs to happen for that much buoyancy? That’s pufferfish territory.
So no, a “tiny percentage” increase in body volume driven by empty chamber “inside” his body would not be enough.
