I thought about this
Upon reading this.
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.
What the story doesn't cover is how the laser equipped dolphins melted the medulla oblongata of the Somali pirates. Sweet.
