Watch: Netting some fishing help from dolphins

The fishing community of Laguna, Brazil have had an unusual partnership for over a century. They work with bottlenose dolphins (Tursiops truncates) to search for fish—a spectacle that has dazzled tourist and boggled the minds of scientists. Biologists have wondered, what do the dolphins get out of the deal? In a recent study in the Proceedings of the National Academy of Sciences, researchers found these cooperative dolphins eat better and gain an edge in survival. The dolphins tip off humans to where the fish are. The net casting breaks up the schools and makes it easier for the cetaceans to catch.
