From March to May every year, many tourists come to Toyama Bay in Japan to see the blue glittering beaches, and in the dark of night, the blue light dots the coastline of more than ten kilometers, which is a beautiful landscape, and these blue lights are emitted by the "fireflies" known as the "fireflies" on the seabed- the fireflies!
Firefly squid is one of the small squid, squid body length is generally 6-8 cm, living in the middle of the ocean zone, in the 182.9-365.8 meters deep sea activity, in the deep sea glowing, through the light source to attract the arrival of prey, when the prey "self-casting net", quickly with powerful tentacles to catch the prey!
During the day, the firefly squid live in the depths of the sea at a depth of 100 meters, and at night, they will come to the shallow layers to find food, especially during the breeding season of the firefly squid, they swim to the sea very close to the shore, so you can see the blue light emitted by the firefly squid dotting the coastline!
Why is Toyama Bay in Japan the best place on earth to see the firefly squid? It is due to the special geographical structure of Toyama Bay, because Toyama Bay has a V-shaped submarine valley, where the seabed suddenly falls, and the current often surges up from the bottom, pushing those firefly squid to the top, so that is the best place to watch the blue coastline!
The glowing squid's luminous device grows in the tentacles, but the glowing place of the firefly squid is not only in the tentacles, the whole body of the firefly squid can emit light, because its body is distributed with tiny light emitters, through coordination, it can be consistent or alternately glowing, forming a beautiful blue pattern, attracting the eye!
The glower and the photosensitor interact with the firefly squid, according to the degree of light, if the light is bright, the firefly squid will not emit light, but the life of the firefly squid is very short, the average life is about one year!
