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 river dolphins in the Indo-Pacific region, 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 techniques used for tools are well-studied in female dolphins, this study specifically looked at male dolphins.

Fungus sponges spend more time associating with other male fungi than they do non-fungi, these bonds are based on similar feed techniques 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 believed incompatible with the needs of male dolphins in Shark Bay – investing time In forming close alliances with other men, this study suggests that, like their female counterparts, and indeed as human beings, dolphins constitute social bonds based on common interests. "The study gives a new insight into homosexual behavior in it. 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 of nested alliance. These strong bonds between men can last for decades and are critical to every man's mating success. very happy to discover alliances of fungi, dolphins form close friendships with others with similar characteristics.
