Acoustic behaviour of bottlenose dolphins under human care while performing synchronous aerial jumps

Synchronous behaviours occur when two or more animals display the same behaviour at time. However, mechanisms underlying this synchrony are not well understood. In study, we carried out an experiment to determine whether Bottlenose dolphins use acoustic cues performing a known synchronised exercise. For this, recorded three while they performed requested aerial jumps both individually synchronously in pairs, with hydrophone array and 360° underwater video camera allowing identification of subject emitting vocalisations. Results indicated that their 100% Whether jumped alone produced click trains before after 92% jumps. No whistles burst-pulsed sounds were emitted by during The localisation process allowed successful vocalising 19.8% all cases (N = 141). Our study showed (n 28) but one localisations, individual. It is worth noting individual was oldest female group. This paper provides evidence suggesting synchronous behaviours, cues, particularly trains, coordinate movements; possibly eavesdropping on clicks echoes leading navigation.
