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 | Bdellovibrio bacteriovorus | African Savanna Elephant |
|---|---|---|
| Physical traits | The accompanying electron-tomography slice shows a microscopic bacterial cell. This is a scientific imaging view, not its appearance to the unaided eye. | 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 | Documented isolates include freshwater fish-pond water and activated sludge. Different isolates need not have identical growth preferences. | 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 | Susceptible Gram-negative bacteria provide resources for growth. Experimental prey panels demonstrate that susceptibility varies among bacterial species. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Predation can occur against free-living cells and cells in biofilms. A mixed-species community does not necessarily protect susceptible prey. | 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 | Growth is linked to access to suitable prey. An increase in predator abundance therefore depends on both prey identity and availability. | 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 | Data unavailable | 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 activity can influence the structure and function of natural and engineered microbial communities. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | Predatory specialization has encouraged aquaculture and wastewater research, but experimental promise is not evidence that every application is established or safe in every setting. | Data unavailable |
