Godzilla, coldblooded or warmblooded?

This is actually a really, really good question. I wonder if they'll address this in the movie/book/prequel comic?

Perhaps he's an inbetween . A mammal like reptile?

It definetly would be interesting to see what blood type he is.

He'd be warm blooded.

You don't need to be a mammal to be warm blooded. Great white sharks are warm blooded, for example.

A creature of his size would have to be warm blooded in order to survive.

Now, I might be getting my facts wrong here and it just isn't biologically possible, but what if Godzilla could actually switch between the being cold and warm blooded? Warm blooded during active periods where there's no worry of overheating his nuclear reactor of a body, cold blooded when it's time to cool off and rest up a bit. If that doesn't work, alright then. Just make it partial warm/cold blooded, like leatherback turtles.

I agree with THEGMAN123. It makes sense. Godzilla would need to cool down his body with all that nuclear fission in his body. Plus his body would need to warm up before a combat situation so he isn't slow and sluggish in a fight.

Godzilla is Blue-Blooded..

There's no need for something that's both warm-blooded and cold-blooded because warm-blooded animals are able to regulate their own temperature. This is why we don't get continuously hotter no matter what we're doing until we explode. Warm-blooded animals are able to regulate heat by sweating, panting, finding shade, or going into water. It is believed that some ancient warm-bloods, such as a the stegosaurus, were able to dissipate heat through their dorsal plates.

Sound familiar?

Duratok beat me to the punch. With an image to boot.
