The '''African bush elephant''' (''Loxodonta africana'') is the larger of the two [[species]] of [[African elephant]].
{{Featured article}}
 
The '''African bush elephant''' (''Loxodonta africana'') is the larger of the two species of [[African elephant]]. Both it and the African forest elephant have in the past been classified as a single species, known simply as the '''African elephant''', but recent preliminary evidence has seen the forest elephant classified as a distinct species (although this status is not conclusively accepted due to concerns over conservation strategies until the reclassification is formalised).<ref name=IUCN/>

Adult males usually live alone. Herds are made up of related females and their young, led by the eldest female, called the [[matriarch]]. Infrequently, an adult male goes with them, but those usually leave the herd when reaching adolescence to form bachelor herds with other elephants of the same age. Later, they lead a solitary life, approaching the female herds only during the mating season. Nevertheless, elephants do not get too far from their families and recognize them when re-encountered. Sometimes, several female herds can blend for a time, reaching even hundreds of individuals.{{citation needed|date = June 2015}}
