Dolphin whistle varies according to where they live – Mágica Mistura を

Various species of dolphin they have specific whistles for each individual – as if they were a name. They use them to identify themselves, if communicate e maintain bonds, and are able to imitate the whistles of close friends and family.

new study revealed that dolphin location and demographics have a greater influence on the differences in these signature whistles than genetics.

Scientists collected 188 hours of bottle-nosed dolphin recordings (Tursiops truncatus) in the Mediterranean Sea and analyzed the differences in whistles from six different populations. Just as we have accents, dolphins had similarities in their signature whistles according to where they lived. Dolphins from regions with seaweed had higher and shorter whistles, compared to those from areas where the seabed was muddy, for example.
