| Social organization | Not applicable | Generally solitary Source ↗ |
| Physical traits | Small cells require microscopy and validated taxonomic methods for study. Closely related gut methanogens need careful strain-level discrimination. | Dark stripes break up the tiger’s outline. Stripe patterns vary from one individual to another. |
| Habitat and range | The oxygen-poor distal intestine provides a host-associated environment supplied with microbial fermentation products. | Tigers live in varied habitats, including tropical forests, mangrove swamps and temperate forest. |
| Diet and nutrition | Hydrogen-consuming methanogenesis uses products released by other community members, contributing to methane formation. | Tigers mainly hunt large mammals, including deer and wild pigs. |
| Behavior and activity | Surface glycans, adhesin-like proteins and nutrient competition help explain persistence in the intestinal environment. | A tiger usually hunts by stalking its prey and attacking at close range. |
| Reproduction and life cycle | Cell multiplication occurs within suitable anaerobic conditions. Genomic comparisons distinguish strains and newly separated related species. | Data unavailable |
| Geographic distribution | Human-derived isolates and genomic studies document host-associated occurrence. A person's carriage cannot be inferred from a species profile. | Data unavailable |
| Ecological role | Removal of fermentation products can affect interactions among members of the gut microbial community. | Data unavailable |
| Distinctive adaptations | The genome study identified surface glycans resembling those in the gut mucosa and regulated adhesin-like proteins. It also examined consumption of products made by carbohydrate-fermenting bacteria. These results explain potential mechanisms of persistence and microbial interaction; observations in experimental mice do not establish a health outcome for every human carrying this archaeon. | Data unavailable |
