Loxodonta africana – African Elephant
Taxonomic notes: Preliminary genetic evidence suggests that there may be at least two species of African Elephant, namely the Savannah Elephant (Loxodonta africana) and the Forest Elephant (Loxodonta cyclotis) (Roca et al. 2001, 2005). A third species, the West African Elephant, has also been postulated. The IUCN SSC African Elephant Specialist Group currently accepts the single species proposa...
متن کاملThe Release of a Captive-Raised Female African Elephant (Loxodonta africana) in the Okavango Delta, Botswana
Wild female elephants live in close-knit matrilineal groups and housing captive elephants in artificial social groupings can cause significant welfare issues for individuals not accepted by other group members. We document the release of a captive-raised female elephant used in the safari industry because of welfare and management problems. She was fitted with a satellite collar, and spatial an...

متن کاملThe skull and mandible of the African elephant (Loxodonta africana).
In the present study the bones of the skull, excluding the hyoid apparatus, are described. All the bones are aerated by sinuses. In the occipital bone the squamous part is aerated from the sinus of the parietal bone, the lateral part is aerated from the tympanic bulla and the basal part from the sinus of the basisphenoid bone. Condylar foramens and hypoglossal canals are absent. A small interpa...
متن کاملEstimating exposed pulp lengths of tusks in the African elephant (Loxodonta africana africana).
Captive and wild African elephants frequently suffer tusk fractures. Several institutions shorten the tusks of captive elephants to reduce fractures and injury as a result of behaviour within enclosures. Fracturing or coronal amputations that expose pulp lead to pain for the elephant. Estimating coronal pulp lengths may thus help to minimise the risk of pulp exposure during amputations. We aime...
