| Physical traits | This diatom can occur as oval, spindle-shaped or three-armed cells. A comparison of the Pt3 strain showed shared features of the plastid, nucleus and cytoskeleton across those forms, alongside differences in protein secretion. The oval form released proteins faster in that experiment, showing that changes in outline can accompany functional differences. | 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 | Marine and coastal-associated culture conditions support this model diatom. Strain and environmental conditions affect the observed growth form. | 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, with dissolved nutrients supplying the other materials needed 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 | Cells respond to changing resources and conditions through physiological and morphological variation. | 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 cell division expands cultures. This account does not infer a sexual schedule merely from that of other diatoms. | 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 | Authenticated isolates have individual collection records; their laboratory distribution should not be used as a global occurrence map. | Native to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species. |
| Ecological role | Diatoms participate in aquatic primary production and nutrient cycling, with species differing in physiology and structure. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | A genome shaped by gene-family changes and ancient gene transfers provides a varied metabolic repertoire. | Data unavailable |
