A story in our world news column of our local paper...Thought it was
REALLY cool! Enjoy! ------------------------------------------
Whangarei, New Zealand. A pod of dolphins is being praised for
providing a protective barrier around a group of swimmers who were
being threatened by a great white shark off the northeastern coast of
New Zealand. Rob Howes and three other lifeguards were on a training
swim about 100 yards off shore at Ocean Beach near here when the
dolphins raced in and herded the group together. "They started to herd
us up, they pushed all four of us together by doing tight circles
around us", Howe said. He said he spotted a 10-foot-long shark cruising
toward the swimmwers. They were surrounded by the dolphins for 40
minutes before they were able to make it back to shore.

I think this proves that they are friends of men.
