Outline of life forms

Outline of life forms (W)

Life form (also spelled life-form or lifeform) is an entity that is living, such as plants (flora) and animals (fauna). It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, are extinct.

Archaea

Archaea (W)

Archaea – a domain of single-celled microorganisms, morphologically similar to bacteria, but they possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably the enzymes involved in transcription and translation. Many archaea are extremophiles, which means living in harsh environments, such as hot springs and salt lakes, but they have since been found in a broad range of habitats.

Crenarchaeota – a phylum of the Archaea kingdom. Initially
- Thermoprotei
  - Sulfolobales – grow in terrestrial volcanic hot springs with optimum growth occurring
Euryarchaeota – In the taxonomy of microorganisms
- Haloarchaea
  - Halobacteriales – in taxonomy, the Halobacteriales are an order of the Halobacteria, found in water saturated or nearly saturated with salt.
- Methanobacteria
  - Methanobacteriales – information including symptoms, causes, diseases, symptoms, treatments, and other medical and health issues.
- Methanococci
  - Methanococcales aka Methanocaldococcus jannaschii – hermophilic methanogenic archaea, meaning that it thrives at high temperatures and produces methane
- Methanomicrobia
  - Methanosarcinales – In taxonomy, the Methanosarcinales are an order of the Methanomicrobia
- Methanopyri
  - Methanopyrales – In taxonomy, the Methanopyrales are an order of the methanopyri.
- Thermococci
  - Thermococcales
- Thermoplasmata
  - Thermoplasmatales – An order of aerobic, thermophilic archaea, in the kingdom
Halophiles – organisms that thrive in high salt concentrations
Korarchaeota
- Korarchaeum cryptofilum – These archaea have only been found in high temperature hydrothermal environments, particularly hot springs
Lokiarchaeota
Methanogens
Nanoarchaeota
- Nanoarchaeum equitans – This organism was discovered in 2002 and lives inside another archaea.
Psychrophiles – (sigh-crow-files)
Thaumarchaeota – a phylum of the Archaea proposed in 2008 after the genome of Cenarchaeum symbiosum
thermophilic – (a thermophile is an organism)

Eukaryote

Eukaryote (W)

Eukaryote – organisms whose cells contain complex structures enclosed within membranes.

Unikonta
- Opisthokonta
  - Animal – multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.
