NOTE: multi-cephalic reptiles have been noted repeatedly. Among mammals and humans this malformation (twinning or duplication of the body axis) is mostly lethal. "Siamese" or conjoined twins are called "cephalopagus" if fused at the "cephalon" or "caput". "Pagus" points to "pago and apego" which today in Spanish may be used to described "attachement" to the home land or in general.
