Coral fluorescence is one of the many mysterious things that draws aquarium hobbyists to reef tanks like moths to a flame. And it apparently draws a lot of divers to venture out on dangerous night dives as well. Armed with intense blue lighting rigs, the crew from FireDive Gear took to Masbat Bay in the Red Sea to view various marine organisms, and the resulting footage just blows us away. Demoed in the annotated short version above, the clip shows images of the corals during the day followed immediately by a video clip of each of the fluorescing corals at night. The list of animals featured in the video includes a Tridacna maxima clam, feather starfish, hermit crab, a handful of different fish, cuttlefish, octopus, and a neon green carpet anemone. While the video above is a couple of years old, we couldn’t pass up the opportunity to share its beauty with all of you. MORE: Amazing Fluorescing Corals Seen During Red Sea Night Dive
