The Firefly Squid is a bioluminescent squid growing to a length of only three inches.
The squid is equipped with special light-producing organs called photophores that emit a deep blue light.
Large photophores can be found on the tips of the tentacles as well as around the eyes.
In the Toyama Bay, in the central Japan Sea, the squid are found in fantastic abundance.
The spawning season of the firefly squid also runs during the same period.
Millions of squid come together to fertilize and to drop their eggs in the Toyama Bay.
Firefly squids is also considered a delicacy in Japan.
These light shows are thought to serve several functions.
They can be used to communicate with potential mates or rivals.
They may also be used to disguise the squid’s shape and confuse predators, allowing it to escape.
