S. Ramakrishnan refers :
Sea Turtles sail through several thousand miles from far east to Tamilnadu / Orissa shores.. they can sail about 85 Km a day, but they could cover vast distance by floating without swimming - using the undercurrent in sea !! Atleast 53 such shores through out East - Far East - have somehow or other related to Tamil names / cultures / traditions !! It can be evidneced that Ancient Tamil Kings used these guidelines and well connected through sea-ways : SAYS ( OUR RESPECTED MEMBER )ORISSA (kalinga) Balu !!
