Photographed off the coast of Okayama, Japan, The Weeping Stones is a photo series by the creative duo Trevor Williams and Jonathan Galione of Tdub Photo that captures the eerie blue light emitted by a native species of bioluminescent shrimp. More commonly referred to as sea fireflies, these rare creatures live in the sand in shallow sea water, floating somewhere between the extremes of high and low tide. At just 3 mm in length the shrimp are extremely small light sources, but when grouped together they take on abstract patterns that light up the water around them.

In order to group such a large number of sea fireflies, or Vargula Hilgendorfii, together Williams and Galione had to collect the creatures by luring them with raw bacon into jars and repositioning their tiny bodies on the rocks. Photographing and placing the bioluminescent shrimp next to the shore ensured that the photographers did not harm them, and allowed them to quickly return the animals back to the water below.

This fall, Tdub Photo hopes to shoot more bioluminescent images by focusing on glowing mushrooms. You can see an earlier project the duo created with bioluminescent shrimp on their website, and see more of their travels over on their Instagram and Facebook.
