Yes for some of them, but the point raised by Greg is the _major_
issue. Nothing lives at or even close to 400 C; they live "near" the
vents, in regions of lower temperature. Some live at quite normal or
even cold T.

Best to ignore the post about GC content; not only does it  raise a
_minor_ point, it is so mixed up on the basics of DNA and protein as
to be useless.
