Upon donation or selecting "Tell me more about this!", Blathers the curator will say:

The firefly squid is a wee migratory squid that barely reaches three inches in length. And though they usually live in deep water, they do venture to the coast to spawn. Like their firefly namesakes, these sparkling squid emit a blue bioluminescent glow. This glow may be used to threaten enemies, communicate with friends, or, perhaps, to lure food in. Truth be told, we do not know for sure why the firefly squid glows. We remain in the dark, as they say.”

Further Information

Main article: Firefly squid on Wikipedia

The firefly squid (Watasenia scintillans), also commonly known as the sparkling enope squid or hotaru-ika in Japan, is a species of squid in the family Enoploteuthidae. It is the sole species in the monotypic genus Watasenia. These tiny squid are found on the shores of Japan in springtime during spawning season, but spend most of their life in deeper waters between 200 and 400 metres (700 and 1,300 feet; 100 and 200 fathoms). They are bioluminescent organisms and emit blue light from photophores, which some scientists have hypothesized could be used for communication, camouflage, or attracting food, but it is still unclear in the scientific community exactly how this species uses their bioluminescence. The firefly squid is a predator and actively hunts its food, which includes copepods, small fish, and other squids. The lifespan of a firefly squid is about one year. At the end of their lives females return close to shore to release their eggs, then die shortly thereafter.
