The massive Humboldt squid has adapted to climate change. But that’s a challenge for fishing communities who depended on it.
Climate change is forcing the creatures of the Earth to adapt or perish. This is the story of one creature that adapted but, in doing so, forced a more painful adaptation on some human creatures.
Michael Fox reports at PRI’s the World, “On a late afternoon in Kino Bay, Mexico, Gerardo Hernandez is repairing his fishing nets. He strings them out in front of his home, made from old pieces of plywood and corrugated tin.
“He lives along the Gulf of California, the body of water that separates most of Mexico from the Baja California peninsula. Hernandez, a seasoned fisherman now in his 60s, can still remember the time of the giant Humboldt squid — a massive invertebrate that used to grow up to 6-feet long. Their abundance made for a robust squid industry fueled by 2,000 fishing boats — the vast majority being small pangas like Hernandez’s.
‘There were always a ton of squid,’ Hernandez said. ‘You would go out, and you’d see them on the surface of the water. The more squid you took, the more there were.’
“The days of the giant jumbo squid are over now. About 13 years ago, after a hurricane and an abnormally warm El Niño year, the squid disappeared from the Gulf. Eventually, they returned. But by 2015, they were gone again. Scientists attribute the shift to animal adaptation amid a rapidly changing climate.
“Hernandez’s kids say they want him to retire now. But he still goes out fishing every night with other members of his small fishing cooperative, and they mostly catch Pacific Sierra fish and crab. He said he brings home enough — but not nearly as much as he did in the days of the Humboldt squid.
“ ‘They’ve left,’ Hernandez said. ‘They’ve emigrated. Only God knows where they’ve gone.’
“But scientists think they have an idea. They say they haven’t actually disappeared. Instead, the Humboldt Squid that live in the Gulf have shrunk from about 6-feet long to less than a foot, and they’re sticking to deeper depths and cooler waters offshore.
“Stanford University biologist William Gilly said the squid seem to have developed this strategy long ago to deal with fluctuating water temperatures that come with El Niño cycles. … It’s a species that seems evolved to adapt to the warming waters brought on by climate change. At least, that’s the theory.
“ ‘There’s a lot we don’t know,’ said Rufino Morales, a fisheries biologist and the coordinator of the Producto Calamar subcommittee, a Mexican group that researches and supports squid fishers. ‘We assume that the shift is due to climate change, or global warming, or because it coincides with El Niño, but these are scientific theories. We haven’t been able to prove them yet.’
“The squid seem to be adapting. The fishing communities they used to support are trying to as well.
“On a warm afternoon in La Manga, a fishing village about an hour west of the port city of Guaymas, a handful of residents gutted a stack of manta rays, whitefish and parrotfish caught that morning. …
“ ‘When the squid was abundant, this was another Guaymas,’ said Maria Collins, a member of the Francisco Flores small fishing cooperative in town. ‘We lived well.’ When the squid left, a lot of people lost their jobs. …
“Many fisherfolk now work in factories off the highway on the northern side of town. Others are doing construction, gardening or plumbing.
“Some boats began to hunt for jellyfish, which they sell to Asian markets. But the season is short. Locals up and down the coast say none of the catches are doing well. They blame the large sardine ships for overfishing and depleting stocks.
“ ‘We are fishermen in danger of extinction,’ said Hernandez as he repaired his fishing net. ‘I think everything that’s happening in the ocean is our fault. Like, we aren’t taking care of it. Or, we don’t care for it, and there’s the proof.’ ”

Good story. I remember hearing about making jellyfish a delicacy. I’ll have look that up and Humboldt squid.
You are a true adventurer!
That the best compliment ever 😊
Sad changes. Sorry to hear the squid no longer get so large.
But they’re living!
Can’t help but feel glad for the squid even if it is hard for those who fish.
It’s the first time I realized that some of our endangered species may be able to figure out the next stage on their own.
Species can evolve quicker than was previously thought by Darwin, etc.
Man’s slow destruction of so many species is frustrating and sad. In the last month, I read a book about the grizzlies, saw a film about the snow leopard, and am now listening to a book about striated cara caras, a fascinating bird in the Falkland Islands. All of these animals will probably be extinct in my kids lifetime.
Interesting about the squid adaptation. You’d think they’d have some Humboldt squid DNA lying around that they could compare with the DNA of the miniature versions to see if they’re related.
The proliferation of movies and books like that are spreading ideas about how to help. But you are right: for some species, it may be too late.
I feel as though I’ve been hearing about this stuff since the age of 10. Occasionally, ecologists manage to impact human awareness and political will to the point where the destruction slows down but there’s a steady march toward creating a planet that may have difficulties supporting even human life if we keep it up. A quote from a book I’m reading: “Definition of progress: cover in 10 hours what Marco Polo took 4 years to cross.” Humans have distanced themselves so far from nature that I think many never give it a second thought. Sorry for the rant. I know we’re basically on the same page.
