Dolphins are incredibly intelligent creatures. The ocean-dwelling mammals are pretty much the people of the deep, blue sea, so it makes sense that a group of bottlenose dolphins have teamed up with fishermen in the Brazilian town of Laguna to keep each party equally happy with their haul of the day.
A group of about 20 dolphins in the area have chosen to work with the humans.
While other dolphins hunt on their own, these guys seem to prefer the symbiotic relationship.
Scientists believe that the behavior must be passed from the mothers of this group down to their calves…
Similar to the way the fishermen teach their children to work with the dolphins.
The men and women of Laguna can recognize each individual dolphin by its markings.
The dolphins use special signals — like a language — to let the fishermen know when and where to cast their nets.
Incredibly, their combined efforts have been going on for over 120 years.
Other collaborative human-animal relationships like this are very rare…
But in this instance, both sides win.
The fishermen don’t need to necessarily divide their spoils with the dolphins, because the fish swimming away from the nets head right into the dolphins’ mouths.
But there’s no real rhyme or reason to it…
The dolphins show up to fish whenever they feel like it, often leaving the men hanging with their nets.
