Photographing a Coral Wall’s Inhabitants

From the Field posts

Curator John Sparks is blogging weekly about the upcoming exhibition, Creatures of Light, which opens on Saturday, March 31.

One of the amazing things about working on an exhibition is having the chance to incorporate our own research—sometimes, very recent research.

Within the past year, including just last December, my colleague, Museum Research Associate David Gruber (CUNY), and I have gone on multiple expeditions to the Cayman Islands and the Exumas, Bahamas, to photograph a coral wall and its inhabitants at night using special lights and filters to capture biofluorescence.

The phenomenon of biofluorescence results from the absorption of electromagnetic radiation at one wavelength by an organism, followed immediately by its re-emission at a longer, lower-energy wavelength. With special cameras, we captured brilliant red, green, and orange fluorescing corals, anemones, mollusks, marine worms, and a myriad of fishes, including sharks and rays.
