For over a decade, John Ng has been diving in the waters around Hong Kong and overseas, taking amazing photos of the extraordinary sea life and marine animals.

John is a diving coach and a self-taught underwater photographer, and also the captain of his own boat, the "Scuba Monster", reports China Daily Asia. 

Before becoming a diver and underwater photographer, John was in the rental business. But he left it as the 9 to 5 job left him no time to be close to the nature.

Watch this video of his amazing works in underwater photography.
