You think you are a good fisherman? Well, you are probably not as good as these dolphins. It’s easy for people to catch fish with nets, but can they do it without them. These dolphins have a fascinating tactics for catching a huge amount of fish. They swim in circles beating the floor with their tail to raise the mud, thus they create a kind of a mud net. Then they go on swimming in tighter and tighter circles until they force all the fish on a small area where they capture them! Fascinating!
