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 | Nostoc commune | African Savanna Elephant |
|---|---|---|
| Physical traits | The visible jelly-like mass is a colony containing many microscopic cells embedded in extracellular material. A colony is not a single large cell. | 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 | Terrestrial colonies can alternate between wet and desiccated states as local conditions change. | 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 | Photosynthesis captures light energy. Laboratory measurements track oxygen production as one sign that photosynthetic activity has recovered after rehydration. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Dry colonies can become metabolically inactive and resume measurable activity when water returns. Recovery is not unlimited and depends on storage 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 | The studied colonies persist through drying and rewetting rather than behaving like short-lived mushroom 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 | 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 | Intermittent hydration makes the species relevant to understanding photosynthetic communities on surfaces exposed to drying. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | Long-term storage experiments found better preservation under cold conditions than at room temperature. Such experimental survival should not be turned into a universal lifespan claim for every wild colony. | Data unavailable |
