This guy kind of took us by surprise. I was busy taking photos of hundreds of black-axil chromis when all of a sudden he/she emerged from the depths. Obviously feeding on the fine plankton in the water that was also attracting the chromis. Pretty thrilling, once you get over the shock of 4-5 metre wide manta ray swimming straight at you! I love mantas!
