Compare their characteristics
| Trait | Prochlorococcus marinus | African Savanna Elephant |
|---|---|---|
| Physical traits | Individual cells are tiny and require microscopy or other analytical methods for study. Pigments and genetic markers assist identification. | 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 these phototrophs. Different ecotypes occupy contrasting light and nutrient conditions. | 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 supplies energy and fixes inorganic carbon. Dissolved nutrients remain necessary for growth. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Physiological performance depends on environmental light and resource availability; ecotypes have distinct genome and protein signatures. | 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 increases cell number through division. Ecotypes describe biological variation, not separate life stages of one cell. | 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 group is important in warm oceanic waters. Ecotype-specific records are more informative than a uniform global range. | Native to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species. |
| Ecological role | These cells contribute primary production to marine microbial food webs and biogeochemical cycling. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | Small cells and differentiated light responses help explain ecological success in dilute ocean environments. | Data unavailable |
