Archaea have molecules with reactive side chains in their plasma membrane, so the tails of archaeal phospholipids form covalent bonds with one another. As a result, the plasma membrane is---  less fluid.

Archaea's membranes are made up of glycerol-ether lipids. Its ether bonds are chemically more stable than ester bonds, so it helps archaea to survive in extreme temperatures and extreme pH environments.
