Tusk
From Wikipedia, the free encyclopedia
A tusk is an
extremely long tooth of certain mammals that protrudes when the mouth is
closed. Tusk-bearing mammals include elephants, warthogs, walruses, and narwhals.
Tusks are used to produce ivory,
which is used in artifacts and jewelry, and formerly in other items such as piano
keys.
Since most tusk-bearing
mammals are endangered (especially the African elephant), the ivory trade is
severely restricted by the United Nations Convention on International Trade in
Endangered Species of Wild Fauna and Flora (CITES). It is unknown if or when
this restriction will end.
