Elephants communicate with sounds within the audible range of the human ear, but also with infrasonic sound. These are very low frequencies that are not audible for humans. But they are for elephants. With these sounds, elephants can communicate over very long distances.
The group of elephants in Emmen is of interest, as it is the largest herd of elephants in Europe. It was noted that Radza, the bull, did not ‘talk’. The seven females and six children, on the other hand, ‘talked’ remarkably much. For now, it is assumed that Radza does not need to ‘talk’ in order to communicate. No one challenges his authority, he is the only male in the group and weighs 7,2 tons. The heavy chattering in the rest of the group, compared to other groups of elephants, is probably caused by the high amount of youngsters.
