  • Bioluminescent Firefly Squid (Watasenia scintillans) ( ほたるいか , hotaru-ika ) emits intense flashes of light from three tiny luminous organs (photophores) that are located at the tip of each of a pair of ventral arms. Light is also produced from hundreds of other minute organs that are scattered over the body. It is thought to be used for Counter-illumination as a method of active camouflage and they can be used to communicate with potential mates or rivals. The Firefly Squid, is only 8 cm and the luminescence of their tentacles light up like glow sticks during mating season or do to prey defence. In Toyama Bay, in the central Japan Sea, the squid are found in abundance. Normally living at 400m underwater. Toyama Bay lies above a deep, v-shaped canyon in which the sea floor drops away suddenly. The flow of the ocean currents usually wells up from the bottom of this canyon and pushes the squid to the surface. Occasionally the squid can be found washed up on the shore in large numbers. Toyama Bay, Japan | Der Leuchtkalmar (Watasenia scintillans) besitzt drei kleine Leuchtorgane (Photophoren), die sich an der Spitze eines jeden ventralen Armes befinden und biolumineszieren können. Weitere kleine Leuchtorgane befinden sich über den Körper verteilt, aber hauptsächlich auf der unterseite des Tieres. Es wird vermutet, dass sie dazu dienen den Schattenwurf (Counter-illumination) gegen die Oberfläche zu vermindern. Aber sie werden sicherlich auch zur komunikation von Tieren untereinander verwendet.

  • Bioluminescent Firefly Squid (Watasenia scintillans) ( ほたるいか , hotaru-ika ) releasing eggs into the water. The spawning season of the firefly squid runs from March to May. During this time, the squid can be seen gathering in large numbers in Toyama Bay in Japan. They gather here by the millions to lay their eggs. Once the eggs have been released into the water the adult squid begins to die. This completes the one-year life cycle of the squid. Toyama Bay, Japan Dawn in Toyama Bay, Namerikawa, Japan  | Die Leuchtkalmare (Watasenia scintillans) haben ihre Laichsaison von März bis Mai. Während dieser Zeit kommen die Tintenfische in flachere Wasserschichten. Die Eier werden aneinander gereiht, wie an einer Schnur in das Wasser abgegeben. Damit ist der einjährige Lebenszyklus des Tintenfisches abgeschlossen. Toyama-Bucht, Japan

  • Dawn in Toyama Bay. Fisherman haul up glowing nets of florescent sea critters. Those are the neon blue flashes from thousands of Firefly Squid (Watasenia scintillans) ( ほたるいか , hotaru-ika ) squirmed around in the nets. It is Hotaru Ika season for the fisherman: every year in spring, these bioluminescent cephalopods come to Toyama Bay to lay there eggs in the open water.
