Whale breaches out of water
Spectacular: The huge whale shows its splendour as it jumps out of the water
For the next hour they watched the whale breach around 40 times and then dive down waving its tail above the water. 
Michael said: 'We all believed it was a least a show of pure joy, if not thanks.
'We were all proud and thrilled that we saved this fantastic young life.
'It was an incredible experience that none of us will ever forget.'
On the video a small girl can be heard saying: 'I know what she is doing. She is showing us that she is free.
Her mother replies to her: 'I think she is showing us a thank you dance.'
Michael spends two months every winter photographing whales in the Sea of Cortez.
He is the co-founder of the Great Whale Conservancy (GWC) Blue Whale Protection Program, set up to protect whales along the California coast from ship-strike caused injuries and death.
