When darkness falls, the world in the ocean is a different place. Diving during the daytime allows you to enjoy many things from far away, but at night, all you can see is what is directly in front of you.

Watch the video to see marine life in the dark ocean off the coast of Nan'ao County, south China's Guangdong Province.
