Friday Squid Blogging: The Evolution of Squid Eyes

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2022/01/friday-squid-blogging-the-evolution-of-squid-eyes.html

New research:

The researchers from the FAS Center for Systems Biology discovered a network of genes important in squid eye development that are known to also play a crucial role in limb development across animals, including vertebrates and insects. The scientists say these genes have been repurposed in squid to make camera-lens-type eyes.

Friday Squid Blogging: Deep-Dwelling Squid

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/friday-squid-blogging-deep-dwelling-squid.html

We have discovered a squid — (Oegopsida, Magnapinnidae, Magnapinna sp.) — that lives at 6,000 meters deep.

:They’re really weird,” says Vecchione. “They drift along with their arms spread out and these really long, skinny, spaghetti-like extensions dangling down underneath them.” Microscopic suckers on those filaments enable the squid to capture their prey.

But the squid that Jamieson and Vecchione saw in the footage captured 6,212 meters below the ocean’s surface is a small one. They estimate that its mantle measured 10 centimeters long — ­about a third the size of the largest-known magnapinnid. And the characteristically long extensions observed on other magnapinnids were nowhere to be seen in the video. That could mean, says Vecchione, that this bigfin squid was a juvenile.

Friday Squid Blogging: UK Recognizes Squid as Sentient Beings

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/friday-squid-blogging-uk-recognizes-squid-as-sentient-beings.html

This seems big:

The UK government has officially included decapod crustaceans–including crabs, lobsters, and crayfish–and cephalopod mollusks–including octopuses, squid, and cuttlefish–in its Animal Welfare (Sentience) Bill. This means they are now recognized as “sentient beings” in the UK.

Friday Squid Blogging: Squid Game Cryptocurrency Was a Scam

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/11/friday-squid-blogging-squid-game-cryptocurrency-was-a-scam.html

The Squid Game cryptocurrency was a complete scam:

The SQUID cryptocurrency peaked at a price of $2,861 before plummeting to $0 around 5:40 a.m. ET., according to the website CoinMarketCap. This kind of theft, commonly called a “rug pull” by crypto investors, happens when the creators of the crypto quickly cash out their coins for real money, draining the liquidity pool from the exchange.

I don’t know why anyone would trust an investment — any investment — that you could buy but not sell.

Wired story.

In what maybe peak hype, Squid Game has its own cryptocurrency. Not in the fictional show, but in real life.

Friday Squid Blogging: Squid Eating Maine Shrimp

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/10/friday-squid-blogging-squid-eating-maine-shrimp.html

Squid are eating Maine shrimp, causing a collapse of the ecosystem. This seems to be a result of climate change.

Maine’s shrimp fishery has been closed for nearly a decade since the stock’s collapse in 2013. Scientists are now saying a species of squid that came into the Gulf of Maine during a historic ocean heatwave the year before may have been a “major player” in the shrimp’s downturn.

In 2012, the Gulf of Maine experienced some of its warmest temperatures in decades. Within a couple of years, the cold-water-loving northern shrimp had rapidly declined and the fishery, a small but valued source of income for fishermen in the offseason, closed.

Anne Richards, a biologist at the Northeast Fisheries Science Center in Woods Hole, Massachusetts, and Margaret Hunter, a biologist with the Maine Department of Marine Resources, studied the collapse and found that it coincided with an influx of longfin squid, a major shrimp predator.

Netflix has a new series called Squid Game, about people competing in a deadly game for money. It has nothing to do with actual squid.
