This foto was taken in Kanniyakumari (கன்னியாகுமரி) Tamilnadu - India, The best part in the foto is that, you can find three oceans joining at the edge of India. Three oceans named Indian Ocean, Bay of Bengal and Arabian sea are joining at a point with which you can clearly see the difference in the color of sea water with your naked Eye. Hope you can differentiate between the color of water in the picture.
