context_page_description: An extreme environment is a habitat that is considered very hard to survive in due to its considerably extreme conditions such as temperature, accessibility to different energy sources or under high pressure. For an area to be considered an extreme environment, it must contain certain conditions and aspects that are considered very hard for other life forms to survive. Pressure conditions may be extremely high or low; high or low content of oxygen or carbon dioxide in the atmosphere; high levels of radiation, acidity, or alkalinity; absence of water; water containing a high concentration of salt or sugar; the presence of sulphur, petroleum, and other toxic substances.
  Examples of extreme environments include the geographical poles, very arid deserts, volcanoes, deep ocean trenches, upper atmosphere, Mt Everest, outer space, and the environments of every planet in the Solar System except the Earth. Any organisms living in these conditions are often very well adapted to their living circumstances, which is usually a result of long-term evolution.
context_section_description: There are many different species that are either commonly known or not known amongst many people. These species have either adapted over time into these extreme environments or they have resided their entire life no matter how many generations. The different species that are able to live in these environments because of their flexibility with adaptation. Many can adapt to different climate conditions and hibernate if need be to survive.
  The following list contains only a few species that live in extreme environments .
