  • SRC The tusks are composed of ivory ( dentine ) beneath the outer layer of enamel , but the peculiar diamond pattern of the elephant ’s tusk gives it a distinctive luster that ivory tusks of other mammals such as hippos , warthogs , walruses , and sperm whales do n’t have , and African elephants are sometimes killed by poachers just for their ivory tusks .
