Thousands of glowing shrimps on the cliffs of Seto beach

The members of Tdub Photo happened to witness this interesting phenomenon in 2015. At that time, their plan was to take pictures of fireflies at the beach at night. Trevor Williams and Johnathan Galione – two photographers from Tdub Photo saw the interesting biological phenomenon and quickly worked to capture one of the rare moments in their career.

“The pictures are very good quality, but honestly I think we can do better. That has motivated us to work on the work in the latest edition of the group. This time, we captured the moment these creatures climbed a cliff at the beach and it made us feel like the rock was crying,” the two photographers shared on their blog.


The scientific name of the strange shrimp is Vargula Hilgendorfii, but many local residents prefer to call them “umihotaru” – sea fireflies. They live mainly in shallow water near the coast and feed by swimming around the shore during high or low tide. This shrimp has the ability to glow for about 20-30 minutes and they can repeat the bioluminescence process when exposed to seawater.

Tbud Photo’s creations provide a detailed look at how they took the photos and include instructions on how to capture and release those special shrimp back into the ocean. At about 3mm small, these shrimp look exactly like blue diamonds moving across the sand.


To be able to catch them, you need to use some container with a lid. During this trip, the 2 photographers used an 8-liter jar, punched holes in the ends and then dropped the bait inside.

This shrimp needs to add more seawater so that they can glow longer and more brightly.
