Archaebacteria
Habitat:
Arcahebacteria are known as extremophiles, which means that they live in climates with extreme temperatures and resources. These extreme habitats include the extreme heat of oceanic vents, the freezing cold of ice, and climates with high salt or pressure. The climates of their residence divide archaebacteria into many groups. Thermophiles prefer extremely hot climates of 80 to 110 degrees Celsius. Halophiles prefer to live in environments with high concentration of salt. Anaerobes are archaebacteria that will die in the presence of oxygen. These include methanogens, which convert carbon dioxide into methane.
Evolutionary Milestones:
Archaebacteria have no milestones, as they are the first organisms to exist, and are the first to appear on the phylogenetic tree.

Anatomical Structures/ Features:
*Cells walls of archaebacteria have no peptidoglycan.
-The proteins the cell walls contain are also some of the same as the proteins of the Eukarya domain.
-The proteins the cell walls contain are also some of the same as the proteins of the Eukarya domain.
Eating and Fleeting:
Most archaebacteria use heat or light to produce energy for survival. Despite this, other archaebacteris are heterotrophic or chemotrophic, using outside energy and chemicals, respectively. Archaebacteria are preyed on by fungi and other types of bacteria.
Symmetry:
Since they are single cells, symmetry is not applicable to archaebacteria.
Movement:
They move using flagella to propel them where they are moving to. They can twist it in a corkscrew movement and glide on secreted slime as if they were floating.
Reproduction:
Archaea reproduce asexually by binary fission, fragmentation, or budding. Unlike bacteria and eukaryotes, no known species forms spores. In binary fission, a single cell splits, leaving two cells with their own circular DNA. Although no offspring is produced through conjugation, genetic material can still be transferred between cells.
Development:
These 3 are the most common shapes. Bacteria do not grow or develop in the same way that humans and other animals do. There are no adolescent or adult stages, as the bacteria is born into its specific shape with a fully functioning body.
Examples:
- Halobacterium salinarum
- Thermococcus litoralis
- Thermoplasma volcanium
Other Information:
-Most bacteria fall into 3 shape categories: spheres (Cocci), rods (Bacilli), and spirals (Spirilli).
-Anatomical features can differ from cell shape to number/lack of flagella.
-The proteins the cell walls contain are also some of the same as the proteins of the Eukarya domain.
-Archaebacteria were not discovered until about 1970
