Seaing is believing. Seeing, and hearing, for yourself the amazing life, colors, and dynamics of the ocean environment is invaluable. Divers invariably have a greater appreciation of the underwater world after experiencing it first hand. Not only do you get to see things you don’t normally see walking on the shore or even snorkeling, but you experience the alien deep water environment, with the changes in pressure, currents, and changes in light and sound. Different locations seem like different worlds – even the same location at a different time of day is completely different. Some organisms are active during the day, some at night, some at twilight or dawn.
So dive in and experience the ocean world for yourself. Just make sure to get the proper training, and always go fully informed, with the proper equipment, and a buddy you trust.
Diving at night reveals a different world. Animals such as snapping shrimp are more active at night. Turn off the light and note the natural lights and sounds around you.
