elephants are conspicuously expressive and joyful creatures. when celebrating a birth or reuniting with old acquaintances, elephants will intertwine their trunks together and engage in friendly trunk wrestling. when trying to console a loved one, or simply showing affection, elephants will stroke or caress each others’ heads and backs with their trunks. the end of an elephant’s trunk is more sensitive than a human’s fingertips. photos by mario moreno
