They discover that the names that can hide more information
Los Dolphin They are very social animals with complex communication systems. As with humans, these cyttakin lives in societies and depends on interactions between them to maintain a healthy social balance. His way to define others is through Distinguished yellowsNow a recent study indicates that these biles can contain more information than identity.
As the marine environment scientist also explained ekaterina ovsyanikovaFrom the University of Queensland (Australia), in an article in ConversationDolphins “use different sounds, such as Storm and zero pulsesTo communicate. “These biles can be classified into two adorable categories: those distinctive, distinctive and unique biles for each individual, the rest, not distinctive.

A certain contrast In the whistle versions produced by each animal. “
For this reason, the research team analyzed “balance between Stability and change Of the distinctive whistles to check if it can contain More information From the simple identity of Westler. “
To do this, they recorded frequent audio recordings for a group of young dolphins in Indopacific. “We collect Many cases Distinctive whistles produced by the same animals. We also use the historical data collected from the same group 15 years ago.
After analyzing the data, the researchers discovered that “although the whistles frequency patterns were exceptionally stable, they somewhat varied.” According to Ovsyanikova, “this indicates that although the distinctive bile frequency patterns cod the identity, it is also possible to do so They convey more informationhow Emotional or contextual signals“.
The results also indicated that “” Males show greater contrast In its distinctive tractions that females can, “which” are linked to the differences in its social roles and the nature of its interactions with others. “

Like the distinctive whistles, our faces combine stability and volatility in their” information package “.
