U V Night Diving

Dive into another realm with psychedelic colours, fluorescent corals and glowing sea life.

What is coral fluorescence? Under Blue Ultra Violet light some species of corals exhibit a phenomenon known as fluorescence where the coral appears to glow in shades of green, red or blue. Corals that normally appear dull brown in the daytime or under white light can take on vivid rainbow hues at night. This is only visible with use of our Blue Light UV Torches and special Visors.

Corals fluoresce when certain pigments inside them react to the strong light, absorbing the cooler blue end of the spectrum and reflecting back shades of greens and reds.

The phenomenon of Coral Fluorescence is still full of mystery and the reasons why certain corals fluoresce are to this date unknown. Strangely enough not all corals fluoresce, and only a few species possess this unique property, which further complicates the search for the reason why corals glow in the first place.

There are several theories provided by scientist, and perhaps the most likely reason is that it acts as a kind of “sun block” for the coral protecting the zooxanthallae inside the coral from the harmful rays of the sun. Marine Biologists say that this property could perhaps protect shallow coral from bleaching or provide deeper coral the ability to absorb the UV light from the sun and reflect it back to the zooxanthallae allowing them to photosynthesize in the absence of sufficient sunlight.

Prepare to be hypnotized by a magical array of psychedelic colours- fluorescent orange, blue, yellow, green, red and purple. Glowing corals, sponges, fish, shrimps, moray eels, crabs and other sea life, you won’t be disappointed
