Description

Archaebacteria are unicellular prokaryotesthat have easily found cell membranes. They are different from most life forms and most are autotrophic.

3 Main Phyla

  • Thermoacidophiles-
  • live in hot springs and can be found in places such a Yellowstone National Park. They can survive in temperatures up to 325 degrees. Also they are found in cracks of the ocean floor.
  • Methanogens-
  • live in volcanoes and insides of animals producing waist such as methane gas. Also they are found in some marshes. Interestingly they cannot live in the presence of oxygen.
  • Strict Halophiles-
  • Which live in salty conditions such as the Dead Sea. They can only live and survive in very salty areas. Surprisingly this is odd because salt kills most bacteria.

Example Animal: Methanocaldococcus

    This animals genus name is:Methanococcus and its specie name is:jannaschii. The Methanocaldococcus is a single celled micro organism that can only live in conditions of 85 degrees celcius. This organism doesn't really eat but instead it takes energy from hot spring water and then mixes in with the cold sea water which surrounds it. It was first found when researchers were finding samples when they found the sample on the base of a ridge in the Eastern Pacific Ocean. Some eye catching facts about this organism is that scientist believe that it may have once also lived on Mars if remains of hot springs are found there. As well as scientists are now experimenting on how this organism can develope new energy and improve human health and the environment. They also believe that through the experimens these organisms will give them the information about the functions of cells and how they work. These small organisms are also believed to be a key into knowing the earth's nitrogen and carbon usage. It is thought by many scientist that this could be a missing link in life. They believe that if they study it more they may be able to find how life was created. They think Methanocaldococcus may be the link to eveloution.
