Trunk-to-Genitals

Reaching of the trunk to touch, or near touch the genitals of another. Trunk-to-Genitals is a common behavior and occurs between elephants of all age/sex groups in a broad range of contexts. It is likely that such behaviour is often related to assessment of physical or sexual state, such as male assessment of female receptivity and female and male assessment of male musth state, or assessing the physical state of an infant.

Yet, it is not always the case that this behavior has an olfactory function. For instance calves Soliciting-Suckling have been observed to touch and even ‘pinch’ their mother’s genitals in an action that appears to be aimed at getting her attention. Likewise, mothers and allomothers touch the genitals of infants, apparently to get their attention before moving off or in an attempt to Guide them toward or away from something. Mothers and allomothers also regularly touch the genitals of infants in what appears to be a gesture of reassurance.

Trunk-to-Genitals often occurs during greetings between various age/sex individuals and during Sparring mostly between males. Elephants are very tactile animals with a tremendously perceptive sense of smell. More research is required to fully understand why elephants touch the genitals of other elephants.
