Elephants utilize their keen sense of touch in social interactions and communication by using physical contact to bond with one another, show affection, and convey emotions. They use various forms of tactile communication such as touching each other's trunks, bodies, or ears to communicate information like reassurance, greetings, or establishing dominance within the herd. Touch also plays a crucial role in the care of elephant calves, as they rely on physical contact with their mothers and other herd members for comfort, guidance, and protection.
