Chain catshark! 

You don’t have to get out of the water—these sharks (Scyliorhinus retifer) are very small. The catshark was first witnessed to be fluorescent during an August 2005 research cruise in the Gulf of Mexico, but no photos were taken. This is one of the first images to capture this shark’s biofluorescence! Captured by David Gruber, Vincent Pieribone and John Sparks.

Marine biologist and National Geographic Emerging Explorer, David Gruber, has discovered a “glowing” sea turtle, the first of its kind to encounter humans. Gruber was filming coral off the coast of the Solomon Islands when he came across what he described as a “bright red and green spaceship”. The strange UFO turned out to be the first biofluorescent sea turtle ever discovered.

Hippocampus erectus!

Biofluorescence of the seahorse, Hippocampus erectus, recorded using a Red EPIC camera at the Mystic Aquarium during a nighttime photo shoot. The red on the body is likely due to algae on the outside of the skin; the green from the grass is due to fake seagrass. But, the compound causing the green fluorescence in the eyes  is still unknown! This is one of the first images of seahorse biofluorescence. Photo: David Gruber, Vincent Pieribone, John Sparks.

Biofluorescent Hawsbill Turtle!

This biofluorescent hawksbill turtle was first imaged on a full moon night in a remote region of the Solomon Islands.  Although the Solomon Islands possess the largest rookery for hawksbill turtles in the oceanic South Pacific, globally E. imbricata is critically endangered and remains under threat from climate change, illegal trade, by-catch and legal subsistence take. The novel observation of fluorescence in E. imbricata highlights the urgency to understand and better protect and manage this critically endangered species.

Hippocampus erectus…

Biofluorescence of the seahorse, Hippocampus erectus, recorded using a Red EPIC. Seahorses are unique because the male get pregnant! After an elaborate mating ritual, the female transfers her eggs to the male’s pouch, where they are fertilized, develop and hatch. When the babies are born, he undergoes sharp labor contractions to expel the newbies. This beauty is the star of Reefs Illuminated. Photo: David Gruber, Vincent Pieribone, John Sparks

Just clowning around

A non-fluorescent clownfish illuminated by its fluorescent anemone home. This image was taken at night at a reef in the Western Province of the Solomon Islands called Shark Point. Two divers held home-rigged bright blue lights while cinematographer Ken Corben hovered above with a underwater Red EPIC camera system.
