FLUORESCENT NIGHT DIVING – A DIVE CHANGING EXPERIENCE! Even the most seasoned divers respond with amazement to their first fluorescent night dive. The reef is simply another world all of a sudden. Terms often used to describe the experience are; “Extraterrestrial”, “Disco diving” and “a different dimension”. Fluorescence is a completely passive phenomena that occurs in some aquatic creatures. It costs them no energy, and the evolutionary purpose of the reaction is still not fully understood by scientists. What is known is that some aquatic animals and corals simply glow when a specific wavelength of light is shone on them, while others look no different than they do on a normal night dive. Coral conservationists use the fluorescence to identify “coral recruits” on reefs. Coral recruits are coral polyps that have attached themselves to the reef substrate to form a new colony. They are tiny and hard to see during the daylight, but are very visible during a fluorescent dive as bright little dots. The dive will be at The Hole in the Wall.
