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 befor the vast number of dolphins. The spectacular scene continued for a while.
The NY Times is skeptical, though it concedes that the US military has been training dolphins for years, so maybe the Chinese have perfected the use of dolphins as an anti-piracy force.
