Tanglefoot, Australia’s only cold-weather deciduous species, attracts thousands to witness ‘the turn’. However, few will have seen them glowing in gold tones. The organism emits garish colours in response to UV light in a process called bio-fluorescence. This particular evening brought subtle aurora and airglow, a rare synergy in these forests.Photograph: Benjamin Alldridge/Australian Geographic

The fire salamander is biofluorescent. The amphibian emits turquoise light when exposed to ultraviolet radiation. This phenomenon had gone unnoticed despite decades of study. 😱 What is the purpose of biofluorescence, and what substance causes it?

A recent study reveals that 37 out of 45 birds-of-paradise species exhibit biofluorescence, absorbing UV or blue light and emitting it as vibrant colors. This phenomenon enhances males' courtship displays and may serve as camouflage for females. Nature's wonders never cease to amaze!

#Biofluorescence: Unseen world of the #Celtic #rainforest revealed by UV
By Paul Pigott, February 17, 2024
"An eerie glow has been emanating from #Wales' #forests and #rockpools for the country's annual dark skies week.
"David Atthowe, a nature guide from Norwich, was invited to shine his ultraviolet (UV) torches on some of the best nature spots in Pembrokeshire and Monmouthshire.
"His photos of temperate rain forest in Wales reveal shapes, structures and colours that rival a coral reef.
"'It is hidden from our human senses, waiting to be discovered,' he said."

A survey of hundreds of frogs in South America shows that far more frogs are biofluorescent than previously thought. Could it be that the ghostly colors may have a role in the way they communicate with members of the same species? Science News dives in.

Fluorescent Friday : Hurghada Departure
Some creatures underwater have the ability to absorb light and re-emitted at a longer wavelength.
Coral, Red Sea, EgyptUsing a yellow filter scuba divers can observe this awesome aspect of nature. The filter can be attached to a divers mask. Underwater photographers and videographers will also need to add a yellow filter to their camera lens to capture the light spectrums.
Lizardfish, Red Sea, EgyptThese underwater photography were taken during night dives in the Red Sea, off the coast of Egypt.
Coral, Red Sea, EgyptHere are more details about my camera set-up and approach to capturing fluorescent images during night dives.

Fluorescent Friday
I have always been intrigued by how and why some creatures fluoresce above and below the waterline.
Biofluorescence is the absorption and reemission of light from living organisms. Fluorescent organisms have proteins built into their skin or other tissues that absorb energy from light and reemit it as a different colors. This results in a wonderful display of color.
In the ocean, blue light penetrates through the water, where some organisms absorb that energy, and then emit light at a lower energy in colors such as green or red. This article from Dive Photo Guide dives into the science of fluorescence as it applies to underwater photography.
Scuba divers need special yellow filters to see the reemitted light. In addition to my normal camera set-up, I used a blue light, and yellow filters on my camera lens and on my mask. Below are the additional items I used to capture the video above.
- Sealife Sea Dragon Mini Fluoro Light
- This light came with yellow filter for a scuba diver’s mask.
- Since this was my first experience with fluoro diving and I was not sure how it would work. I selected a lower end mini model and was pleased with the results. However, if I have the opportunity to upgrade, I would go with the higher model that has a wider beam range. For non-photographers/videographers, the mini would suit them well.
- Tiffen Yellow Filter
- The yellow barrier filter blocked any reflected excitation light and transmit only the fluorescence from the subject.
- Basically, allowed me to record exactly what I was seeing through the mask filter.
- It’s a wet lens, so I just attached it to the front of my underwater camera housing.
I shot this video off the house reef at Six Senses Laamu Resort during our first night dive there. The Laamu Atoll is located in the Maldives.
Overall, I was amazed by the color captured during the night dive. I will plan to try again on my next night dive. Hopefully, I can schedule the night dive around coral spawning. This is the time when corals colonies reproduce by releasing their eggs and sperm all at the same time. However, with a global pandemic, I’m not sure if I’ll be able to coordinate this year.

This is cool. Frogs and salamanders are biofluorescence.
"Amphibians, one of the world's most imperiled groups of vertebrates, can biofluoresce. Frogs, salamanders, and caecilians can absorb light from their environment and then emit it at different wavelengths, resulting in brilliantly bright greens and other colors."
