Critters at Lembeh Resort Dive Centre Manager Brigitte Gassner is a huge fan of blackwater and bonfire diving where she is able to spot and photograph critters at their larvae stages. Many of the sightings during these dives are critters which are unseen by the majority of underwater photographers and scuba divers. Brigitte has even been able to spot a paper nautilus at one of Lembeh Resort’s closest dive sites.
Brigitte is passionate about sharing these new diving experiences with guests staying at the luxury Lembeh Resort located on the banks of the Lembeh Strait. But what is bonfire and blackwater diving and how is it different to other night dives?
It all Starts with Plankton
There are two types of plankton; zooplankton (which is animal based) and phytoplankton (which is plant based). These two forms of plankton drift with the ocean currents and are the source of all marine life. The word “Plankton” is derived from the Greek word “Planktos” which translates into English as “drifter” or “wanderer”. Did you know that in one teaspoon of sea water there are literally billions of life forms?
What is Blackwater and Bonfire Diving?
Blackwater diving takes place over deep water, away from the reef. In Lembeh, blackwater dives usually take place in the middle of the Strait. Bright lights are suspended in the water column at various depths up to 25 meters. The lights attract plankton in the water column which in turn attracts intriguing and rarely seen larvae stage critters.
Bonfire diving takes place at shallower depths on the reef or sandy slope – in Lembeh, there is no shortage of suitable dive sites. Bonfire diving is also based around the use of bright lights to attract plankton and both larvae stage and more mature critters.
Blackwater and Bonfire Underwater Photography Subjects
The most iconic blackwater and bonfire dive critters include crustacean and cephalopod larvae and of course the paper nautilus which, to many, is the ultimate of all critters. Other common subjects include jellyfish and other critters which drift freely in the open ocean. Many larvae stage critters do not yet display any coloration and are often translucent as they are still in the early stages of development. Both types of diving feature a lot of critter behavior spotting and imaging opportunities.
Jellyfish are often behavioural hotspots, look out for jellyfish playing host to a range of species from tiny amphipods through to jackfish. The jackfish will enter the jellyfish and use it for protection, it’s often possible to see the jackfish going in and out of the jellyfish as it exits it host to breathe before re-entering.
Blackwater and Bonfire Photography Techniques
Blackwater and bonfire photography require using fast shutter speeds – typically sync speed, as you are capturing images of larvae which is moving. A fast shutter speed will help to “freeze the action”. Shooting with a small aperture, which gives more depth of field, allows for more of the critter to be in focus as opposed to only a small section which is closest to the lens.
Best Times for Blackwater and Bonfire Diving
It’s technically possible to blackwater and bonfire dive at any time but Brigitte says the most abundant dives are around the new moon – up to 4 days before and 3 days after. Around the new moon there is little moon light so the bright dive lights become more active. When there is a full moon there is already light on the surface so the level of activity is dispersed and less centered around the dive lights.

Photo Gallery: Dive Fest Barbados
In our Gallery feature, we let the photos tell the story… Each Gallery showcases a selection of outstanding images on a chosen theme, taken by our Underwater Photography Editor Nick and Deputy Editor Caroline of Frogfish Photography. This time they reflect on their visits to the Caribbean Island of Barbados for the annual Dive Fest celebrations.
Dive Fest Barbados is a week of celebrating the marine life, diving and snorkeling this idyllic island has to offer. There are activities organised each day for all those that attend that include wreck diving, marine conservation, learning to dive, snorkeling and one an unusual dive for us – riding a submarine to the bottom of the Caribbean Sea! Dive Fest Barbados allows divers to get the very best out of a trip here, with plenty of diving, but also to sample the unique atmosphere, mouth-watering food and drink, stunning scenery and beautiful beaches.

Video Series: The CCMI Reef Lectures – Part 4 (Watch Video)
Introduced by Jeff Goodman
Never before since human beings have had major influence over our earths climate and environments, have we come to so close to the brink of global disaster for our seas and marine life. We need to act now if we are not going to crash headlong into irreversible scenarios.
A good start to this is understanding how the marine environment works and what it means to our own continued survival. We can only do this by listening and talking to those with the experience and knowledge to guide us in the right direction.
CCMI (Central Caribbean Marine Institute) are hosting an annual Reef Lecture series that is open to the general public and Scubaverse will be sharing those lectures over the coming months.
Part 4: Stop Whining! Life as an Ocean Ambassador; Ellen Cuylaerts
Ellen Cuylaerts shares her insights on how to act, practice what you preach and use your voice to contribute to constructive change. Ellen is a wildlife and underwater photographer and chooses to take images of subjects that are hard to encounter like harp seal pups, polar bears, orcas, beluga whales and sharks, to name a few. By telling the stories about their environment and the challenges they face, she raises awareness about the effect of climate change on arctic species, the cruel act of shark finning and keeping marine mammals in captivity.
During this seminar, Ellen will take you on a virtual trip and show you the stories behind the shots: how to get there, how to prepare, how to create the most chances to come home with a shot, and how to never give up!
Ellen Cuylaerts is an ocean advocate, underwater & wildlife photographer, explorer, and public speaker.
