Using the trunk to briefly grasp the tail of another. This is perhaps most commonly observed during social play, but males may sometimes grasp the tail of an estrous female, and mothers may hold the tails of their infants apparently to get their attention.
An adult male tests Arora B Trunk-to-Genitals and then sniffs her anus and then continues to Grasp-Tail as she tries to walk away. (Amboseli, Kenya)
