When it comes to making friends, it seems like dolphins are like us and form close friendships with other dolphins who have a common interest. The findings, published in Proceedings of the Royal Society B by an international team of researchers from the universities of Bristol, Zurich and Western Australia, provide further insights into the social habits of these remarkable animals.

Shark Bay, a World Heritage Site in Western Australia, is home to an iconic population of Indo-Pacific river dolphins and the only place where dolphins have been observed using marine fungi as feed tools. This learned technique, which has gone down from generation to generation, helps some dolphins, "fungi," find food in deeper water channels. While the tooling technique is well studied in female dolphins, this study specifically looked at male dolphins.

Use of behavioral, genetic and photographic data collected from 1

24 male dolphins during the winter months of Shark Bay for nine years [2007 to 2015]analyzed the subset of 37 male dolphins, consisting of 13 fungi and 24 non-fungi.

Fungicides spend more time associating with other male fungi than they do non-fungi. These bonds are based on similar propagation methods and not related or other factors.

Dr. Simon Allen, co-author of the study and senior research assistant at Bristol's life sciences school, explains: "Fungus feed is a time-consuming and largely solitary activity, so it was long considered incompatible with the needs of male dolphins in Shark Bay to invest time in forming close alliances with other men. This study suggests that, like female counterparts and, like humans, social bonds based on common interests form. "

The study gives new insight into gay behavior in the social network of tools using dolphins.

Manuela Bizzozzero, lead author of the study at Zurich University, added: "Male dolphins in Shark Bay exhibit a fascinating social system for nested alliance formation. These strong bonds between men can last for decades and are critical for every man's mating success. very excited to discover alliances of fungi, dolphins form close friendships with others with similar characteristics. "
