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 | Tetrahymena thermophila | African Savanna Elephant |
|---|---|---|
| Physical traits | A ciliated cell contains two functionally different nuclei. The micronucleus carries the germline genetic material used in sexual reproduction; the macronucleus is the principal center of everyday gene expression. Both occur within one cell, illustrating a division of genetic roles without the organism being multicellular. | 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 | Freshwater-associated environments and laboratory cultures provide conditions for a predatory single-celled lifestyle. | 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 | Cells acquire nutrients through feeding processes and transport systems, using microbial and dissolved resources according to conditions. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Cilia contribute to locomotion and feeding. Cellular signaling links behavior to environmental conditions. | 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 | Vegetative division maintains cells. During sexual processes, the micronucleus transmits germline information and new somatic nuclear organization is established. | 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 | Research strains document particular lineages. A broad freshwater-ciliate range should not be substituted for verified species 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 | The organism consumes resources within microbial communities and can itself be consumed by other organisms. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | Division of labor between germline and somatic nuclei supports a complex cellular organization without a multicellular body. | Data unavailable |
