Glowing blue objects turning up on Toyama beach


The photo at left has been showing up on various websites recently depicting glowing blue objects lining up along a shore. This beach is in Toyama, and for the locals, this isn’t such a crazy sight.

These are firefly squids who spend their days in the deep Pacific Ocean only to go hunting near the ocean’s surface when the sun goes down.

The reason for their blue glow resembling a new streetlight is bioluminescence, which is a chemical reaction inherent in some animals that cause them to generate light such as these guys’ namesake, the firefly.

The glowing parts are located on half of their limbs and at points along their backs. Their undersides don’t glow to protect them from predators. It may be hard to tell from the picture but the squids are quite small measuring only a few inches in length.

If you’d like to learn more about them, then swing by the Hotaru Ika Museum (Firefly Squid Museum) also in Toyama.

When I lived in Toyama hospitable locals used to love serving up these little creatures as a local delicacy. Virtually any invitation to a meal came with a guarantee that there would be hotaru ika on the table at some point. The one (fire)fly in the ointment in what is otherwise a very nice part of Japan.

I hope this is not a forecast that a big earthquake is hitting Japan any time soon. The Tohoku area is still in a state of shock even though they are moving along. Anyway, this is a wicked picture. I like it a lot actually.

Do they bite? Seriously.

Another horribly misleading headline from rocketnews...

Those squids are pretty cool, just a shame they aren't really all that bright.

Hotaru Ika is really delicious, especially that variety where they are "drowned"/ put in Sake directly from the sea, used as a rice topping.

I find that there are a lot of bioluminescent creatures in the Seto Inland Sea at this time of year. When I swim at night my strokes leave a wake of glowing green.

What are they? Well it says right there in the 2nd paragraph - they are firefly squid, a species of bioluminescent squid that emit their own light.
