Amicrobe is discovered living in an extreme environment near a deep sea vent. the microorganism lacks a nucleus and peptidoglycan in its cell wall, but it does have unusual membrane lipids. this species is most likely a member of the domain

But most importantly, a unique characteristic of Archaea is the presence of ether linkages in the lipids of their cytoplasmic membranes. This  distinguishes archaea from eukaryotes and most bacteria.
