How to compare two organisms
Choose two species and trace their closest shared group. Then compare a trait with the same definition on each side. Check the units, life stage and context before interpreting a measurement or range.
Missing data means that the collection lacks a sourced value. Where a characteristic does not apply to a lineage, the comparison labels it separately. Open the two profiles for context and follow their sources before drawing a conclusion.

| Trait | Dictyostelium discoideum | African Savanna Elephant |
|---|---|---|
| Physical traits | Feeding cells are amoeboid. Developing aggregates, migrating slugs and stalked fruiting bodies have very different appearances. | 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 | Soil-associated and decaying-organic-matter environments provide bacterial food and surfaces for development. | 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 | Vegetative amoebae ingest bacteria. Resource depletion changes development rather than simply producing a smaller feeding cell. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Chemical signaling coordinates aggregation and collective movement during the developmental response to starvation. | 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 | Feeding cells multiply individually. Aggregation leads to a multicellular stage and then stalk and spore differentiation; spores can restart feeding growth. | 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 | Authenticated environmental isolates and laboratory strains have distinct collection histories. Research use is not a complete map of wild occurrence. | Native to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species. |
| Ecological role | Its transition between independently feeding cells and multicellular development makes environmental conditions central to its biology. The genome study identified many systems for producing and exporting small molecules, providing a genetic framework for investigating how an amoeba coordinates behavior with other cells. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | The transition between feeding independence and coordinated dispersal is a distinctive response to changing resource conditions. | Data unavailable |
