Ivory is obtained from the large teeth and tusks of several mammals, including the elephant, hippopotamus, walrus, extinct wooly mammoth, and narwhal. In these animals, an upper incisor grows throughout life into a large tusk. In elephants, for example, the average tusk weighs 7 kilograms, but in large males the weight might be much more. A major factor endangering the continued existence of these extant mammals has been the value of their ivory.
