| Trait | Nitrosopumilus maritimus | Acropora millepora |
|---|---|---|
| Physical traits | Small cells require microscopic methods for study. Electron microscopy and tomography reveal cellular organization beyond what an ordinary photograph can show. | Colonies form branching structures covered by small skeletal cups that house polyps. Colony color alone is insufficient for secure species identification. |
| Habitat and range | Oxygen-containing marine conditions support ammonia oxidation. The original isolate came from an aquarium-associated marine system. | Shallow, well-lit marine reef environments support the coral and its photosynthetic partners. |
| Diet and nutrition | This archaeon gains energy by oxidizing ammonia to nitrite and uses inorganic carbon to build cellular material. The original isolation demonstrated nitrification in an archaeon. Light is not the energy source for this carbon-fixing metabolism, distinguishing it from photosynthetic marine microbes. | Polyps capture small suspended food, while algal symbionts contribute photosynthetic products. |
| Behavior and activity | Activity links energy metabolism to supplies of ammonia, oxygen and other required resources. | Tentacles and mucus help the colony interact with surrounding seawater. Recognition mechanisms influence responses to microbes. |
| Reproduction and life cycle | Cell growth and division maintain cultured populations. Molecular and physiological evidence connect strain identity with measured activity. | Colonies grow by producing additional polyps. Sexual reproduction can release gametes that develop into settling larvae. |
| Geographic distribution | The isolate is related to archaeal lineages detected widely in marine surveys. Related environmental sequences are not automatically exact species records. | The species occurs in the Indo-Pacific reef region. Species-level locality records should accompany detailed range mapping. |
| Ecological role | Its metabolism links marine nitrogen transformations with carbon fixation. | Skeletal growth contributes reef structure and habitat. Symbiotic interactions are central to energy supply and colony health. |
| Distinctive adaptations | The capacity for chemolithoautotrophy provides a route to growth without light-driven photosynthesis or an animal host. | A colonial body and partnerships with photosynthetic cells support growth in well-lit reef environments. |
| Conservation | Data unavailable | Thermal stress, bleaching and degradation of reef habitat are concerns. A source on molecular recognition does not establish a current Red List category. |
