Crenarchaeal
Crenarchaeal refers to things related to the crenarchaeal lineage of archaea, typically the group once classified as the phylum Crenarchaeota. Members of this group are diverse in metabolism and ecology but are commonly associated with high-temperature, acidic, or otherwise extreme environments. The term is used to describe both organisms and features linked to this lineage.
Taxonomy and classification have shifted in modern systems. Traditionally, Crenarchaeota was a major archaeal phylum containing
Key characteristics of crenarchaeal organisms include cellular diversity, typically lacking peptidoglycan in their cell walls and
Ecologically, crenarchaeal lineages are common in hot springs, volcanic and hydrothermal environments, acidic habitats, and other
