Kingdom Monera is broken up as follows:
Subkingdom Archaebacteria – ancient or primitive anaerobic bacteria. Live in conditions too harsh for other living creatures, resembling environments on early earth.
The archaebacteria include:
Methanogens - “methane makers” live in swamps, sewage, animal gut and other anaerobic habitats.
Halophoiles - “salt lovers” live in brackish ponds, salt lakes, near seafloor volcanic vents and other high salinity habitats.
Extreme thermophiles
- “heat lovers” live in hot springs, acidic soils, near hydrothermal vents,
(2500 C).
Quick Fact: Approximately 2,000 species of bacteria have been identified.

Two Examples of different Monerans.
There is some oscillatoria <left> and some gleocapsa <right>
The oscillatoria is from Phylum
Cyanophyta, and the gleocapsa is from Phylum Schizomycophyta.
