| Trait | Sulfolobus acidocaldarius | Acropora millepora |
|---|---|---|
| Physical traits | Cells have small, irregular rounded outlines. Surface structures participate in interactions with the surrounding environment. | Colonies form branching structures covered by small skeletal cups that house polyps. Colony color alone is insufficient for secure species identification. |
| Habitat and range | The genome study describes an aerobic thermoacidophile from terrestrial solfataric springs, with optimal growth around 80 °C and pH 2. Temperature and acidity are separate features of this habitat. The organism is adapted to both, whereas many other archaea occupy environments that are neither hot nor strongly acidic. | Shallow, well-lit marine reef environments support the coral and its photosynthetic partners. |
| Diet and nutrition | Energy and carbon use depend on available substrates. The organism is studied under oxygen-containing, hot and acidic culture conditions. | Polyps capture small suspended food, while algal symbionts contribute photosynthetic products. |
| Behavior and activity | Temperature affects motility and population distribution in experimental work, illustrating an active environmental response. | Tentacles and mucus help the colony interact with surrounding seawater. Recognition mechanisms influence responses to microbes. |
| Reproduction and life cycle | Chromosome replication and cell division sustain populations. Its relatively stable reference genome contrasts with the more mobile-element-rich genome of some relatives. | Colonies grow by producing additional polyps. Sexual reproduction can release gametes that develop into settling larvae. |
| Geographic distribution | Authenticated hot-spring isolates and cultures document occurrence. Not every acidic spring contains the same species or strain. | The species occurs in the Indo-Pacific reef region. Species-level locality records should accompany detailed range mapping. |
| Ecological role | The archaeon participates in specialized geothermal microbial communities. | Skeletal growth contributes reef structure and habitat. Symbiotic interactions are central to energy supply and colony health. |
| Distinctive adaptations | Cellular machinery functions under combined heat and acidity; these are properties of this lineage, not all Archaea. | 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. |
