A fishing community in southern Brazil has an unusual ally: wild dolphins. Accounts of people and dolphins working together to hunt fish go back millennia, from the time of the Roman Empire near what is now southern France to 19th century Queensland, Australia. But while historians and storytellers have recounted the human point of view, it’s been impossible to confirm how the dolphins have benefited — or if they’ve been taken advantage of — before sonar and underwater microphones could track them underwater. In the seaside city of Laguna, scientists have, for the first time, used drones, underwater sound recordings and other tools to document how local people and dolphins coordinate actions and benefit from each other’s labor. The most successful humans and dolphins are skilled at ...

Male bottlenose dolphins form the largest known multi-level alliance network outside humans, an international team led by researchers at the University of Bristol have shown. These cooperative relationships between groups increase male access to a contested resource. The scientists, with colleagues from the University of Zurich and University of Massachusetts, analysed association and consortship data to model the structure of alliances between 121 adult male Indo-Pacific bottlenose dolphins at Shark Bay in Western Australia. Their findings have been published in The Proceedings of the National Academy of Sciences (PNAS). Four male allies and a female dolphin.

The lagoon houses about 155-165 dolphins and 10.5 lakhs water birds, representing 105 different species.

Read MoreFishermen battled on Sunday to save dozens of injured dolphins washed ashore in Mauritius where in recent days at least 40 of the animals were found dead in a lagoon near the site of an oil spill from a Japanese bulk carrier which struck a coral reef. Yasfeer Heenaye, a fisherman near Pointe aux Feuilles on the island’s eastern shore, said he had counted at least 45 dead dolphins since they were first discovered on Wednesday, and said half a dozen more dolphins were in the bay fighting for their lives. He said he believed the animals’ vision was impaired by the spilled oil, which is how they ended up on the reef where they sustained fatal injuries. Dolphins are seen as they swim near the shore of the Indian Ocean near Pointe aux Feuilles, Mauritius August 28, 2020. Picture taken ...
