Watasenia scintillans

Watasenia scintillans, commonly known as the Firefly Squid or Sparkling Enope Squid, is a species of squid in the family Enoploteuthidae. It is the sole member of the genus Watasenia.

Description

The Firefly Squid is small, growing to a length of only 3 inches. It is notable for its light-producing organs known as photophores, which emit a deep blue light. The squid uses this bioluminescence for various purposes, such as attracting prey, communicating with others, and confusing predators.

Distribution and Habitat

Watasenia scintillans is found in the Western Pacific Ocean, particularly around the coasts of Japan. It inhabits deep waters during the day and migrates to shallower waters at night.

Behavior

The Firefly Squid is known for its spectacular displays of bioluminescence, particularly during mating season. Large groups of these squids gather near the surface of the water, creating a stunning light show that can be seen from the shore.

Diet

The diet of Watasenia scintillans consists mainly of small fish and crustaceans. It uses its bioluminescence to attract and disorient its prey.

Reproduction

The Firefly Squid has a short lifespan of about one year. It reproduces once in its lifetime, laying thousands of eggs before dying.

In Culture

In Japan, the Firefly Squid is a popular delicacy and is often served raw as sashimi. Its bioluminescent display is also a popular tourist attraction, particularly in Toyama Bay where the phenomenon is known as the "Blue Tears".
