Thousands of dolphins block pirates?

I had to look through this several times, and still don’t believe what I see.  Take it with a grain of salt, as the original story comes from China.  I thought I’d post it here anyways, as it is certainly interesting, and if true, absolutely amazing. Because we don’t even see the dolphins and the suspected pirates in the same photo, I wonder how true this story is.  I also wonder who is taking the photo?  The photos are a bit grainy, but if you look closely at the ship in the background, it does look like there might be firehose streams from the deck.

The Chinese article reports (with translation errors)-

The Chinese merchant ships escorted by a China’s fleet sailed on the Gulf of Aden when they met some suspected pirate ships. Thousands of dolphins suddenly leaped out of water between pirates and merchants when the pirate ships headed for the China’s.

The suspected pirates ships stopped and then turned away. The pirates could only lament their littleness before the vast number of dolphins. The spectacular scene continued for a while.

China initiated its three-ship escort task force on Dec. 26 last year after the United Nations Security Council called on countries to patrol gulf and waters off Somalia, one of the world’s busiest marine routes, where surging piracy endangered intercontinental shipping.

China’s first fleet has escorted 206 vessels, including 29 foreign merchant vessels, and successfully rescued three foreign merchant ships from pirate attacks.

BEIJING, April 14 (Xinhuanet) -- Thousands of dolphins blocked the suspected Somali pirate ships when they were trying to attack Chinese merchant ships passing the Gulf of Aden, the China Radio International reported on Monday.
