Cause they are tough cookies.
Technically, all bacteria is ancient and has developed over billions of years. The bacteria we find today all comes from a common ancestor. Some ancient bacteria had to thrive in extreme environments, they are known as Extremophiles. These Extremophiles live in environments that other organisms can not, such as high temperatures, extreme pH ranges.
Archaea and Bacteria.
Ancient bacteria can live in very extreme environments. often with little or no oxygen. true bacteria can not do this. Ancient bacteria are often found in hot sulfur springs, muddy environments such as mudflats and swamps, and places deep in the ocean where lava and hot water seep through cracks on the ocean floor. But true bacteria are found EVERYWHERE except extreme environments.
The archaebacteria kingdom is one of the six kingdoms. Organisms in this kingdom are also called Bacteria; they are unicellular and live in very extreme environments. The "common bacteria" belongs to another kingdom; the Eubacteria kingdom, bacteria in this kingdom differ from bacteria in the archaebacteria kingdom and they do not live in extreme environments.
There may be more, but I know one bacterium is Archaebacteria.
Archea Bacteria are a domain of organisms that live in extreme environments.

Archaea and Bacteria.
Most extremophiles are simple, single-celled life forms, yet many are not. Extremophiles occur in all three domains of life: bacteria, archaea, and eukaryotes. ... However, archaea aren't restricted to extreme environments; they live in most of the same places as bacteria
archaebacteria
chemoautotrophs live in very harsh environments.
Bacteria are ubiquitous one-celled organisms, spherical, spiral, or rod-shaped and appearing singly or in chains, comprising the Schizomycota. Bacteria can live everywhere (ubiquity) because there are so many different species all adapted to different environments.
All sponges are aerobic, they need oxygen to live. Some do however, live in low oxygen environments and they can 'house' anaerobic bacteria.
Chlamydia is a eubacteria. Most bacteria are eubacteria unless the bacteria live in extreme environments.
Bacteria that live in extreme environments. The big three live in extremely hot water, super salty water, or extremely acidic water.
