@A Wikia contributor - "Technically they don't need air. Some species have the ability to absorb oxygen from the water through their skin, this allows them to stay submerged for months without surfacing. Some amphibians even have evolved external gills, but for obvious reasons Godzilla is not one of those."

Then explain why Godzilla spends MOST OF HIS TIME IN WATER. He sleeps underwater most of the time and he doesn't drown. Godzilla doesn't drown underwater.
