Bio-Fluorescent Night Diving

We’re always looking to bring you the next new and exciting trend in diving. Over the last couple of years more and more of our diving guests have got to know the psychedelic dance club colours of Glow Diving, or is that Fluo Diving?

Not to be confused with phosphorescence, or bio-luminescence, if you’re Fluo Diving, you’re out to find the Bio-Fluorescence of the coral reef, and its inhabitants.

Fluorescence is the absorption of one colour (wavelength of light) and the re-emission of a totally different colour. Corals do it, reef fish do it and invertebrates do it too! Bio-fluorescent reef inhabitants, under white light, reveal to us their natural colours. Under Ultra Violet light (UV light) they absorb and transform the blue into a brightly glowing, totally different colour.

So whether you refer to it as Fluo Diving, Glow Diving, Fluro Diving or Fluoro Diving. At the end of the day, literally, it’s all about Bio-Fluorescence Night Diving.

Around the world more and more dive centres are taking ‘Black Lights’ out on night dives. Using a UV flashlight underwater on a night dive, the corals and anemones glow brightly. As do critters like Lizardfish and Mantis Shrimp. All Fluorescing for your enjoyment.

Bio Fluorescence underwater is a relatively recent discovery and much is still to be learnt about which creatures fluoresce and why they do it. Perhaps fluorescent proteins act as a sunscreen, or is it part of the photosynthesis process. It may even be used as some form of communication.

Why not find out for yourself on a dive holiday to one of the following dive destinations:

Sulawesi, Indonesia

Formed by fire Sulawesi’s four large peninsulars are mountainous and volcanic, with lush vegetation and off shore islands fringed by coral reefs. Off the western tip of North Sulawesi are the Bunaken Marine Reserve and Bangka Island. Off the peninsular’s north east side is the Lembeh Strait. Bunaken and Lembeh can be combined to experience the best of both in one holiday. Extend your holiday and fly via Java to explore its temples and volcanoes, or via Singapore and add a city stay.

Dumaguete, Philippines

The Negros Island is considered to be outside the Philippines’ typhoon belt, so it enjoys all-around good weather. Rainfall is usually light, although there can be a few heavy rains per year. The wet season covers the period from June to November, and the dry season starts from December to May, the hottest being April and May. December to January usually encounters the “dirty Northeastern winds”, as the locals called it, while the southwestern wind is experienced in July and August. The temperature for the entire province of Negros Oriental ranges from between 22ºC and 24ºC. Maximum temperatures can reach 35ºC in the month of July. The lowest temperatures were recorded in the month of April at 20ºC.

East End Cayman, Grand Cayman

There are numerous things to see underwater around the Cayman Islands such as, pristine reefs, brightly hued sponges, corals and fans, and if your visiting at the right time, 5th, 6th and 7th night after the 9th full moon of that calendar year, you will have the opportunity for a night dive to see coral spawning. Swimming with stingrays at ‘Stingray City’, which is suitable for all ages and levels. Night dives, including ultraviolet night dives, an awesomely eerie experience. One of the best has to be diving down to the Kittiwake Wreck, which was originally a Submarine Rescue vessel.

Bonaire, Dutch Antilles

The diving on Bonaire is a mixture of both boat dives to neighbouring Klien Bonaire (approx 20 minutes away) and shore diving. The Bonaire Marine Park has marked about 80 yellow stones around the shore line marking dive site entry points. All the dive centers offer drive through filling stations (car hire is a must) giving you complete freedom to dive the island with your buddy at your own pace – this is what attracts so many visitors to Bonaire, the freedom to dive where, when and how you want at your own pace. Of course guided dives are always available if you wish.


Within our Maldives liveaboard collection you will find a boat to suit all tastes and budgets. From a simple traditional dhoni design to a purpose-built full service luxury yacht. Maldives liveaboard itineraries are just as varied. Still the most popular is the 7 night Central Atolls itinerary followed by extended 10-14 night itineraries. We also offer ‘fly dive’ itineraries, getting you quickly into remote outer atolls, and two liveaboards permanently located outside Male, one in Meemu in the Southern Atolls, the other in Far North Haa Alifu. Our aim, as always, is to match the perfect boat and ideal itinerary with your diving requirements and holiday expectations. Take advantage of our extensive knowledge of the Maldives island Resorts to add a resort extension either before or after your liveaboard.
