During Sparring, Dueling, Greeting or during the formation of Coalitions, such as High-Fiving or End-Zone-Dance, elephants may click or clank their tusks together. In affiliative and coalition building contexts this has been referred to as Tusk-Clicking, but the sound is much more of a clank during Sparring or Dueling. In the former two or more closely allied elephants may stand either parallel or face-to-face, adopting Head-Raising, Open-Mouth-to-Open-Mouth, and Trunk-Twining may (apparently purposefully) click their tusks together.
