Compare their characteristics
| Trait | Methanosarcina barkeri | African Savanna Elephant |
|---|---|---|
| Physical traits | Rounded cells may occur in packets or aggregates. Growth conditions and strain identity influence cell-surface organization. | Broad ears, a long trunk and column-like legs give the animal its familiar outline. The trunk tip has two finger-like projections. Both sexes can develop tusks. |
| Habitat and range | Oxygen-poor sediments and anaerobic digesters are documented habitats. A rumen-derived strain has also been characterized. | Savannas and open woodland provide a shifting mixture of browse, grass, shade and drinking water. Seasonal water availability influences the places that herds use. |
| Diet and nutrition | Culture studies demonstrate growth with acetate, methanol or carbon dioxide under the appropriate experimental conditions. Substrate combinations, hydrogen availability and changes in medium acidity influence methanogenesis. A list of usable carbon sources therefore does not mean that each substrate supplies an identical or independent route to energy. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Aggregation changes contact with the surrounding medium and with neighboring cells. | Female relatives and their young form long-lasting social groups. Older females hold knowledge of familiar routes and resources; adult males have a different pattern of association. |
| Reproduction and life cycle | Cell division within growing populations can maintain or expand aggregates. These packets are not multicellular animals or fungal fruiting bodies. | Calves are born alive and depend on milk and extended social care. Learning from other elephants is an important part of growing up. |
| Geographic distribution | Strain CM1 came from a ruminant setting, while other documented strains originate from sediments or digesters; these are distinct occurrence records. | Native to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species. |
| Ecological role | Methanogenesis is a terminal process in anaerobic carbon breakdown and contributes methane to natural and managed systems. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | Multiple methanogenic pathways allow use of contrasting substrate supplies. | Data unavailable |
