Dolphin doesn't discriminate. It is his nature to help out any creature in need. He offers his help in treating depression in human beings at some therapeutic centres. He has once gained fame by helping a female pygmy sperm whale together with her calf find their way out of shallow water where they were stranded several times in New Zealand waters. He also has been known to protect humans from shark attacks by bending his brothers together and swimming in a protective circle around the human. Too bad humans are doing little to protect them as they continue to be unwitting victims of unsustainable purse seine fishery.
