Firefly Squid By: Haley Tapper and Alexx ThomasThe Firefly Squid
My Scientific Name: Watasenia ScintillansMy Other Names: Sparkling Enope SquidI am a member of the Cephalopod familyI am famous for the amazing light show that happens when millions of my species gather to mate of the coast of Japan
Geographical RangeI am found throughout the western pacific ocean around depths stretching from 600-1200 feet.During mating season I migrate in large numbers to Toyama bay in Japan
Toyama BayPhysical TraitsI am a cephalopod about 7-8 centimeters long.The photophores on me are special light-producing organs found throughout my body producing a blue body light.The projected light can be flashed in endless patterns, serving many functions such as communications with mates or rivals.I am the only member of the squid family that has color vision. In addition, I also have a double-layered retina in the back of my eyes.These adaptions for color vision helps me decode the patterns of light created from other members of the species I have arms and tentacles and one series of suckersMy mouth cavity has dark pigmentation Bilateral symmetry The animal divided on one plane into two mirror-image halves Heterothermic having a temperature that varies with the immediate environment Ectothermic- must use heat gathered from the environment and behavioral adaptions to maintain constant body temperaturehttp://www.arkive.org/firefly-squid/watasenia-scintillans/video-00.html
Diet and Feeding I flash my blue lights in patterns in which I turn on and off to attract prey and then pounce on them with my tentacles.At night, I migrate to the surface in search for food then return at depths of 1,200 feet.Carnivores Consuming shrimp, crabs, fish and planktonic crustaceans.
Predators My photospheres can be used against as a warning signal against predators or as counter-illumination camouflageThe northern fur seal is a known predatorHumans I can be eaten raw or cookedSperm whalesSharks Larger fishLarger squidCrabs
I use my photospheres to disguise my shape, confusing predators and allowing me to escape
My bioluminescence is a handy survival adaptation that I employ in a handful of different ways. I can intimidate predators with my lights. I can bewilder predators with them, making the outlines of my body unclear and thus buying me extra time to flee hazardous scenes. I can even draw in possible mates using my lights.
ThreatsWe reproduce rapidlyPeople eat us
Breeding season runs from March to May.We gather in large numbers in Toyama Bay in japan to lay our eggs.The adult squid die once their fertilized eggs are released into the water.This completes our one-year lifespanOur eggs hatch in 6 to 14 days depending on the water temperature which can vary between 6 to 16 degrees Celsius.Sexual reproduction
Super cool factsDuring an event referred to locals as squid drowning themselves, we can be washed up on the shore for an interesting light show.As fishing boats haul in their catches, the surface of the sea glows bright cobalt blue.I have over 800 lights on my bodyI spend the day at depths of several hundredmeters& return to the surface when night fallsI can light up my whole body to attract a mate, matting season usually lasts from March to JuneWe are commercially fished in Japan, accounting the annual catch in thousand tons
