english: Now, the signature whistle is a whistle that's specific to an individual dolphin, and it's like a name. (Dolphin whistling noises) And this is the best-studied sound, because it's easy to measure, really, and you'd find this whistle when mothers and calves are reuniting, for example.
non_english: Charakteristické zahvizdnutie je zahvizdnutie príznačné pre konkrétneho delfína a funguje ako meno. (Hvízdavé zvuky delfína) Tento zvuk je najlepšie preskúmaný, pretože sa dá ľahko zmerať. Stretnete sa s ním napr. keď sa matky a mláďatá znova stretnú.
