00:03dolphins are pretty amazing creatures in fact they're likely the second most intelligent ones
00:08on the planet next to humans and that might be why our two species work so well together in fact
00:13on
00:13the southern coast of brazil fishermen and dolphins have been working together to catch
00:16fish for nearly one and a half centuries but how well the dolphins swim into the shallows where
00:21fishermen stand ready then they chase schools of mullet towards the fishermen who then cast
00:25their nets catching many more than they likely would have otherwise simply by waiting it's a
00:29wild natural synergy that has developed over time with the dolphins even signaling for the
00:33fishermen to cast their nets it's what researchers call mutualism where two species help one another
00:38out so what do dolphins get out of it well when the fishermen cast their nets the dolphins often
00:42dive deeper and increase their vocal clicks with researchers saying they believe the fishermen's
00:47nets might disrupt the schools of fish and underwater footage actually reveals the dolphins are able to
00:52snag fish from the nets themselves with the mutualism both increasing the fishermen's catch
00:56while also increasing the dolphins fish intake bettering their chance for survival
