Can you distinguish which part is good,the Chinese merchant ships and Somali pirate ships?It can't be a problem for a man.But is it a problem for the dolphins of the Gulf of Aden?Ha,ha,certainly not,either.Why ? For the dolphins of  the Gulf of Aden can tell justice from evil.They are good judgers.From the news of the China Radio International  on Monday,we can know that the dolphins "drove the Somali pirate ships away "when they tried to attack the Chinese merchant ships.They just did as  the Chinese fleet had done.How wize the dolphins are!

     The dolphins is said the cleverest animals except man,I heard.So,I hope the human being can do more to protect them just like what they have done when the human being need "help".Do you think so?
