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 | Emiliania huxleyi | African Savanna Elephant |
|---|---|---|
| Physical traits | Calcifying cells carry intricately shaped calcium-carbonate plates called coccoliths. Electron microscopy reveals their detailed architecture. | 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 | Illuminated marine waters support photosynthetic growth. Different strains have contrasting ecological capabilities. | 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 fixes inorganic carbon. Calcification is a separate process and should not be equated with a simple net removal of atmospheric carbon dioxide. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Population blooms occur under suitable conditions. Different genomes and metabolic repertoires contribute to environmental responses. | 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 life cycle includes a diploid phase, commonly bearing calcium-carbonate coccoliths, and a non-calcified haploid phase with two flagella. Diploid cells can also be non-calcified. A field mesocosm study detected both calcified and non-calcified cells during bloom succession, so lack of a visible coccolith covering does not by itself exclude this organism. | 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 | The cited genomic study describes extensive strain variation associated with habitats from equatorial to subarctic waters. | Native to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species. |
| Ecological role | Organic-carbon production, calcification and export to deeper water give the group a complex role in the marine carbon cycle. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | Coccolith formation and substantial between-strain genomic variation are distinctive features. | Data unavailable |
