Many halophiles, thermophiles and other extremophiles belong to this class of organisms.
The cell walls of some of these organisms cannot be degraded by lysozymes because they are composed of pseudomurein. Their cell membranes contain branched hydrocarbons and are primarily composed of ether-linked lipids instead of ester-linked lipids. Those that use carbon dioxide to oxidize methane are called methanogens, and, like many of these organisms, are poisoned by (*) oxygen since they are obligate anaerobes. Many halophiles, thermophiles and other extremophiles belong to this class of organisms. For 10 points, name these prokaryotes named after the fact that they are much older than other forms of life.
