They are Humboldt squid, Dosidicus gigas. Posted by: John Moore at March 30, 2007 3:33 PM No where as good as the beach orgy shot in the same directory. Posted by: Anonymous at March 30, 2007 3:53 PM They're part of the flying squid family, Ommastrephidae. 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. Posted by: Jeff Parkhurst at March 30, 2007 3:54 PM Once you know to search on "La jolla Cove", there are lots of hits involving squid. http://news.nationalgeographic.com/news/2005/02/0223_050223_giantsquid.html Perhaps you should try a local squid dish if you are ever passing through Bruce. Posted by: Browser at March 30, 2007 4:34 PM 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? Posted by: Anonymeese at March 30, 2007 5:17 PM I don't want to be on that beach in a couple of days. Pew! Posted by: bear at March 30, 2007 6:04 PM 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. --- from: National Geographic on 2/23/2005 ( http://tinyurl.com/5mta9 ) 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. 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." ---- Posted by: David Donahue at March 31, 2007 1:03 AM Mad Squid Disease? If cows can be infected by prions, why not squid? Posted by: nostromo at March 31, 2007 10:45 AM This appears to be from somewhere in Mississippi. http://scienceblogs.com/deepseanews/2007/04/hurricanes_leads_to_the_incurs.php Posted by: Squid vs. Calamari at April 1, 2007 9:12 AM Haven't you seen "Supersize Me"? They ate at Mickee D's. :) Posted by: FooDoo at April 4, 2007 4:35 PM Post a comment
