Dolphin creates ‘net’ using sand. Moments later camera catches unique ocean phenomena


People living in the municipality of Laguna in southern Brazil, derive practical benefit from the proximity of dolphins: these animals help them to catch fish. In turn, dolphins also learned something from people. Biologists from the Federal University of Santa Catarina have been studying the behavior of bottlenose Dolphin species from the Brazilian Lagoon for many years.

Living here marine mammals actively cooperate with man, “working” in team. First dolphins drive shoals of mullet towards fishing vessels or the shore, and then with nods or blows tail on the surface of the water to signal people where to cast their nets. They also don’t go hungry: fish, not get caught in the nets, floats in it’s mouth.
