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 | American Black Bear | African Savanna Elephant |
|---|---|---|
| Physical traits | Black coats are common, but brown and other color forms occur. A relatively pale muzzle and the absence of the brown bear’s prominent shoulder hump can help 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 | Forests with cover and diverse food sources are important, although the species uses a broad range of wooded and adjoining habitats. | 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 | Leaves and other plant growth, fruits, nuts, insects and animal foods contribute in different seasons. Human food can alter natural foraging and create avoidable conflict. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Black bears climb well and often forage alone. Activity can shift with season and disturbance, so a single daytime or nighttime label does not describe every population. | 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 | Females give birth to dependent cubs in winter dens. Cubs remain with their mothers while learning to find food and negotiate the landscape. | 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 Mammal Diversity Database v2.5 records this species in Canada, Mexico, United States. | Native to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species. |
| Ecological role | Data unavailable | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
