Bending or kneeling down and tusking the ground and, often, uplifting clods of soil and vegetation. When elephants engage in Mud-Wallowing they often Tusk-Ground. This is particularly true of Mud-Wallowing musth males who will engage in an exaggerated form of Tusk-Ground along with other components of a musth male display. In an Aggressive context Tusk-Ground is seen in the manoeuvring between two males during an Escalated-Contest, apparently as a demonstration of ‘look what I will do with you’.

In an Attacking & Mobbing context an elephant may Kneel-Down and Tusk a person or other animal into the ground to kill or maim it. During Social Play elephants engage in a gentle form of both Kneel-Down and Tusk-Ground, behaviors that encourage other elephants to Climb-Upon.
