Content: walrus tusks are upper canines. Tusks and teeth are formed of the same four parts: enamel, cementum, dentine and pulp cavity. These parts are shown in an elephant tusk above but are included in all other forms of ivory regardless of animal species. The mammals which provide ivory are: 1) elephants (order Proboscidea) which include species alive today (extant) as well as prehistoric elephants now died out (extinct) like mammoths; 2) walrus; 3) whales --sperm, killer and narwhal; 4) hippopotamus and 5) warthog. These groups represent the main sources of commercial ivory used over the years.
