Teeth are not replaced by new ones emerging from the jaws vertically as in most mammals. Calves have brownish or reddish hair, especially on the head and back.

African elephants make use of 8—10 distinct call types [ 24 — 26 ], which grade with intermediate cross-forms between and within different call categories; this affects acoustic parameters including formants [ 27 — 31 ]. These cavities give the inside of the skull a honeycomb -like appearance. Males stay with the family until they reach 12 to 15 years of age, when they leave the herd and live alone or join up with other bulls.
