As I was swimming through the azure waters of Roca Rartida I saw a Giant Black Manta – a beautiful contrast to the endless deep shades of blues before me. It was like a dream, I couldn’t believe I was seeing this with my own eyes. I had to pinch myself and was so glad that I was sharing this small space in the world with such a rare and mysterious creature. I had always wanted to do something like this and Nautilus Explorer made everything possible for me.
