title: Are extreme halophiles actually "bacteria"?
abstract: Comparative cataloging of the 16SrRNA of Halobacterium halobium indicates that the organism did not arise, as a halophilic adaptation, from some typical bacterium. Rather, H. halobium is a member of the Archaebacteria, an ancient group of organisms that are no more related to typical bacteria than they are to eucaryotes.
