Have you heard about the famous firefly squid found in Toyama Bay, Japan? These fascinating bioluminescent squids grow to about three inches long. Their bodies are equipped with special light-producing organs called photophores, which emit a blue light. You can find these photophores on their tentacles and around their eyes, and there are even tiny ones within their bodies, allowing them to glow all over. Toyama Bay, located in the center of the Sea of Japan, is home to many of these unique creatures.
Firefly squids typically live about 1,200 feet underwater. During certain times of the year, the waves push them to the surface. From March to June, which is their spawning season, millions of these squids migrate to Toyama Bay to lay their eggs. This period is famous for the spectacular light display created by the gathering squids, attracting thousands of tourists to witness the event. As squids die, other sea creatures and birds feast on their decaying bodies. The squid is also considered a delicacy in Japan.
In the early dawn, boats leave the fishing port of Namerikawa, which also hosts a museum dedicated to these creatures. The fishermen’s nets, located two kilometers from the shore, capture the squids, and as the nets are pulled in, the light from the squids causes the sea’s surface to glow blue. Many tourists eagerly wait with their cameras to capture this mesmerizing sight.
Scientists believe the light displays serve several purposes: communication among squids, evasion of predators, and attraction of prey. The squids can flash their lights on and off to lure small fish, which they then catch with their tentacles. If you’re planning a trip to Japan, make sure to visit Toyama Bay. While you’re there, don’t miss the chance to taste the delicious squid prepared with vinegar and miso.
