File Under "Dolphin Altruism"

From New Zealand via Yahoo news:

WELLINGTON (Reuters) - A pod of dolphins circled protectively round a group of New Zealand swimmers to fend off an attack by a great white shark, media reported on Tuesday.

Lifesavers Rob Howes, his 15-year-old daughter Niccy, Karina Cooper and Helen Slade were swimming 300 feet off Ocean Beach near Whangarei on New Zealand's North Island when the dolphins herded them -- apparently to protect them from a shark.

 

"They started to herd us up, they pushed all four of us together by doing tight circles around us," Howes told the New Zealand Press Association (NZPA).
