It is believed that on the intelligence scale, dolphins come just below humans. They have big brains in relation to the size of their bodies, are self aware and have a huge capacity for processing emotions. It is no surprise to then see what the dolphin in this video is doing. She swims in a circle around a shoal of fish creating a net of mud so the only way for the fish to escape is by jumping out… straight into the mouths of some hungry dolphins! How clever is that? Take a look!
