what, reptiles HAVE to MANUALLY control their body temperatures, if they don't they loving die, thats why lizards sun-bathe
yeah, but that's not the same thing
why do you think I say they're warm-blooded, its an automatic compensation mechanism that would be required for breathing fire without becoming very fatigued after usage
I may have had the time frames wrong but seriously this is like 1000+ degrees (F) spewing from their mouths, its gonna get really hot really loving fast
warm-blooded animals have just as much trouble with fire as reptiles, if not more. warm-bloodedness definitely didn't come about because of the need to breathe fire (there would also be no need for that in the first place), it most likely came from the need to not spend so much time out of the day sitting around using the environment to regulate their temperature
and why would the fire be that hot?
