If you can enjoy the wonderful world of underwater then I think this video is a must-watch. It is an hour-long but can be watched on full screen. The quality is very good.
It's fascinating to see how the ocean floor changes when the sun goes down! A whole different environment takes place where different creatures emerge from dark volcanic sands. The astonishing behaviour of corals feeding while glowing in the dark. Crustaceans, Cephalopods and Nudibranchs sharing one amazing Underwater World!
