      I mean he clearly just walks out of the water in the movies, he’s not suddenly coming up, like you clearly see him slowly get higher and higher out of the water as he gets closer to shore. Also the ocean isn’t that deep close to shore.

    The new Godzilla Minus 1 movie actually goes over this, >!they even use it against Godzilla to try and defeat him.!<

      My head canon for sea-based Kaiju is they have a sack of muscles somewhere inside their body that can expand a cavity, kind of like the diaphragm expands the lungs, except instead of taking in air or water it just creates a volume of vacuum inside of them. This makes them extremely bouyant relative to the surrounding sea pressure, so they rapidly ascend and can casually float like a boat near the surface.

      But if they ever want to dive again, they just let that cavity collapse and all their bouyancy goes away.

        To get unnecessarily scientific here, that wouldn’t change the overall density of the body, no? Even if there’s now a cavity with vacuum, the matter that was occupying that space just moved somewhere else within the volumes of the body and the overall density remained the same.
        Now, if it pushed some matter out, air or water, and created a vacuum cavity, that might work. But I’m not an engineer, so correct me if I’m wrong.

          A hundred ton steel ship floats, a hundred ton steel block does not. Density equals weight per volume. If you increase the volume without increasing the weight, the density will go down.

            Exactly my point, the volume doesn’t change in the example provided. Weight and volume stayed the same. We either need to expand Godzilla or it needs to eject some mass.

              In the example he gave, he mentioned lungs expanding, so volume IS changing. Godzilla can shoot lasers in current lore. He could easily have some super compressed ballast tanks as organs that release pressure changing a whole slew of variables.

              If Submarines have ballast tanks of 600 pounds of air at 3000 PSI, Godzilla can have his own magic organs that do crazy stuff.

                Expansion of lungs makes us float because our whole body expands significantly, relative to our small volume.
                In the examples mentioned above, the organs creating vacuum are said to be “somewhere inside” the body. Vacuum or not, Godzilla needs to visibly swell to increase its volume and buoyancy, which we don’t observe.

                The air in submarines is used for pushing the water out of tanks, so the principle is ejecting matter. If Godzilla were to use that approach, as I said before, it needs to eject something.

          You’d be right if the cavity is only compressing other organs inside the body without changing the overall volume, but I don’t know why you seem to insist on making that assumption.

          I thought it would be clear from my original description, via the analogy with lungs, that the cavity would not squish the internal organs but rather expand the overall volume of the body.

      He looks badass from the top, but under the water his lil legs are paddling at full speed.

    Everyone always thinks the ocean is super deep from the beach outward. This is not the case. Just because a boat will float seemingly close to shore doesnt mean the hull is way down in the water

      An aircraft carrier only has a draft of some 12 meters. Godzilla is over 100m. Much of the North Sea is only like 40m deep, with shallows much less than that.

        That’s how I usually interpret it except in Godzilla Minus One :

        Tap for spoiler

        A whole plot point is that he is in 1500m of water

    He’s obviously built himself thousands of little elevators over millenia. What did you guys think he was doing down there? Sleeping?
