say hello comes with a range of possible gestures and vocalizations – from a moving ridge of recognize to a squeeze as you draw tight or a shout to get the attending of your friend after you ’ve got a good mesa at a busy taphouse . Now , the same can be aver of the elephant populace : African elephants(Loxodonta africana ) can change their greetings to one another based on whether the other elephant is pay attention .
Using more than just one type of salutation at the same time is know as multimodal communication . These elephant have a whole range ofcommunicationoptions , with combination of ear movements , tactile signals , or unlike vocalizations . The most frequently used vocalisation is a rumble , which includes information about theidentity of the elephantmaking the randomness .
By studying semi - confined savannah elephants living in the Jafuta Reserve , Zimbabwe , the squad witnessed 89 salutation effect , which included 1,282 greeting behaviors . Of these behaviors , 1,014 were physical greetings while the remaining 268 were vocalizations .
Combinations of motion and vocalism were used between elephants recognise each other , include capitulum flap and rumbling , which was the most common combining of greeting . The 2d most commonly seen combo was rumble with ear stiff . The team cogitate that this ear gesture , as well as ears slightly spread aside , might facilitatehearing a responsefrom the other elephant .
Seemingly less pleasant forms of salutation , such as peeing and pooping as well as sweat gland secretion , were used in 71 percent of greetings . The researchers mean this might mean that look play into elephant communication more than was antecedently thought .
Elephants also varied which greeting combo they used found on whether the elephant they wanted to greet was search at them . If the other elephant was looking away , the set about elephant was more likely to use vocalization , gestures that produced a noise , or give them a prod with the conclusion of their trunk .
Interestingly , the squad find that the female in the cogitation greeted each other in a way that was ordered with previous reflection of close bonded violent elephant or related zoological garden elephants . Meanwhile , the males in the study used the same combinations of greetings as the female person , which is not typically image in other studies – waste male elephant unremarkably only growl or raise their shorts to smell other elephants .
The purpose of these elaborate social greeting is thought to be to beef up social shackle and promote recognition , include during distaff reunification and , in this discipline , between closely stick to males .
