Ocean fireflies may gleam like the fireflies that convey lawn guides around evening time, however that is about where the similitudes end between the two species. Researchers call the bioluminescent shellfish washing over these stones Vargula hilgendorfii, and here in Japan they’re ordinarily known as umi-hotaru. They’re noticeable around evening time in the shallow ocean waters and sea shores of Japan, albeit different types of the sort Vargula can be seen gleaming in the waters of the Gulf of Mexico, the Caribbean Sea, and off the California bank of the US. Every ocean firefly is about the size of a sesame seed, yet as a gathering they set off a noteworthy emanation. Their gleam escalates relying upon the saltiness of the ocean water and other physical boosts. Other than illuminating the shores around evening time, the shellfish do their part tidying up the sea shore by chomping on sandworms and dead fish. That is only one less thing for wanderers to stress over during a glinting shoreline walk.
