TraitAfrican Savanna ElephantAmoeba proteus
Physical traitsBroad 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.An irregular outline and flowing extensions distinguish a moving cell. A nucleus and vacuoles can be observed using suitable microscopy.
Habitat and rangeSavannas and open woodland provide a shifting mixture of browse, grass, shade and drinking water. Seasonal water availability influences the places that herds use.Freshwater environments with microbial food and suitable surfaces support its crawling and feeding activity.
Diet and nutritionGrasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth.Pseudopodia surround food particles and small organisms, bringing them into vacuoles for digestion.
Behavior and activityFemale 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.The cell forms pseudopods as its shape changes. Direct pressure measurements found that internal pressure rose before movement and decreased around pseudopod formation, supporting a role for hydrostatic pressure driven by the contractile cell cortex. This links movement with the mechanics of a living cell rather than an animal-like limb.
Reproduction and life cycleCalves are born alive and depend on milk and extended social care. Learning from other elephants is an important part of growing up.A growing cell can divide after nuclear replication. This profile does not assign a complex reproductive stage from another amoeba species.
Geographic distributionNative to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species.Recorded cultures have particular collection histories. Identifying every large freshwater amoeba as A. proteus would overstate its distribution.
Ecological roleFeeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations.Consumption of microorganisms connects it with freshwater microbial food webs.
Distinctive adaptationsData unavailableA deformable cell surface supports both movement and feeding. Contractile-vacuole activity helps manage water balance in freshwater.
