No idea, all I know is that Zoologischer Garten Leipzig is a zoo. And you
did not remember that I told you it's -waran, not -waren. :-)

Well, if you can send the paper in some form, then I could try. Not that I

Yes, varanids cheat, they have an extra complicated lung, as detailed in a

them to be pretty tachyaerobic without being tachymetabolic, apparently.

Why does temperature matter?
