Between the BBC and Google images, it wasn’t hard to find the image or the incident. They are Humboldt squid, Dosidicus gigas.

No where as good as the beach orgy shot in the same directory.

They’re part of the flying squid family, Ommastrephidae.
Yep. It was Ommastrephes gigas at one point, until a revision of the genus.
I used to find the beaks of this species in the stomachs of another Ommastrephid that I was studying;
Ommastrephes bartramii – known as the neon flying squid. They tend to have a slightly larger distribution than O. gigas up the west coast of America as they are a highly migratory oceanic species.
Thanks so much for the Friday Squid….it’s a real nice pick-me-up for this lowly civil servant. And it’s been quite a while since I’ve been out to sea to observe these critters live.
Did someone order a large calamari?

Once you know to search on “La jolla Cove”, there are lots of hits involving squid.
Perhaps you should try a local squid dish if you are ever passing through Bruce.

While I’m sure local squid dishes might be tasty, I wouldn’t want to try one that’s passed through Bruce.
Perhaps one in an area Bruce has passed through?

I don’t want to be on that beach in a couple of days. Pew!

For a guess?
How about a capsized squid fishing boat dumped it’s haul.
Of course, it seems to me that it’s more likely it’s a natural phenomenon.
I did some looking about and found that it’s been happening for years and scientists don’t know for sure what it is.

Last month thousands of large squid mysteriously beached themselves on California shores.
It was not the first time such a mass “suicide” has occurred. Observers say it seems to happen every few years.
But what causes the Humboldt—or jumbo—squid (Dosidicus gigas) to end up on land?
“We don’t know,” said William Gilly, a biologist at Stanford University’s Hopkins Marine Station in Pacific Grove, California. “It’s a mystery of large size what’s killing these squid.”
Gilly has studied squid for more than two decades and has been tagging the jumbo squid in Mexico’s Gulf of California as part of a larger study of their movements in the Pacific Ocean. He speculates that the cause of the recent deaths might be a combination of the squid spending too much time in warm water and the squid eating something toxic.
Sarah Allen, a senior science advisor with the National Park Service at Point Reyes, California, said around 30 squid died on Drakes Beach, north of San Francisco.
The squid did not seem to wash up dead on the shores but instead appeared to swim into shallow water where waves carried them onto the beach. According to Gilly, the Hopkins Marine Station biologist, that suggests there may be something neurologically wrong with the squid.
“They appear to be mentally deranged, not physically ill. It’s clearly something abnormal,” he said. “They’re big-brained, intelligent creatures. It’s not like they’re attracted to the lights of the city or anything like that.”
He speculates that the squid are eating something toxic and that this leads to their aberrant behavior.
The toxin, Gilly said, could be domoic acid, which is produced by several species of microscopic algae known as diatoms.
Studies have shown that domoic acid causes convulsions and even death in marine mammals that feed on the same things that squid do. The acid is found in organisms, including sardines and krill that eat the algae and that are in turn eaten by the squid.
“In addition,” Gilly said, “I suspect there is an environmental wild card that augments the effects of the toxin, most likely thermal stress to the squid from spending too much time chasing food and eating in relatively warm surface water.” —-

Mad Squid Disease? If cows can be infected by prions, why not squid?

This appears to be from somewhere in Mississippi.

Haven’t you seen “Supersize Me”? They ate at Mickee D’s. 🙂
