Folding the trunk under and holding its end off the ground by tucking it between the base of the trunk and a tusk or, alternatively, folding it sideways and laying the lower end tucked back on top of a tusk.
A young male engages in Trunk-Tuck as he Contemplates whether to engage in a bout of play with another young male. He stands with Trunk-Tucked and then walks over to him and touches him Trunk-to-Genitals. He considers a bit more, returning to his Trunk-Tucked posture. Notice his Ears-Stiff - attentive. As a third young male arrives and reaches Trunk-to-Mouth to the middle male, the first young male abandons his Trunk-Tuck stance and Reaches-Over the middle male. They walk off together. (Amboseli, Kenya)
