Friday Squid Blogging: New Squid Species

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2022/08/friday-squid-blogging-new-squid-species.html

Seems like they are being discovered all the time:

In the past, the DEEPEND crew has discovered three new species of Bathyteuthids, a type of squid that lives in depths between 700 and 2,000 meters. The findings were validated and published in 2020. Another new squid species description is currently in review at the Bulletin of Marine Science.

Friday Squid Blogging: Ten-Foot Long Squid Washed onto Japanese Shore — ALIVE

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2022/04/friday-squid-blogging-ten-foot-long-squid-washed-onto-japanese-shore-alive.html

This is rare:

An about 3-meter-long giant squid was found stranded on a beach here on April 20, in what local authorities said was a rare occurrence.

At around 10 a.m., a nearby resident spotted the squid at Ugu beach in Obama, Fukui Prefecture, on the Sea of Japan coast. According to the Obama Municipal Government, the squid was still alive when it was found. It is unusual for a giant squid to be washed ashore alive, officials said.

The deep-sea creature will be transported to Echizen Matsushima Aquarium in the prefectural city of Sakai.

Sadly, I do not expect the giant squid to survive, certainly not long enough for me to fly there and see it. But if any Japanese readers can supply more information, I would very much appreciate it.

Friday Squid Blogging: Squid Skin–Inspired Insulating Material

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2022/04/friday-squid-blogging-squid-skin-inspired-insulating-material.html

Interesting:

Drawing inspiration from cephalopod skin, engineers at the University of California, Irvine invented an adaptive composite material that can insulate beverage cups, restaurant to-go bags, parcel boxes and even shipping containers.

[…]

“The metal islands in our composite material are next to one another when the material is relaxed and become separated when the material is stretched, allowing for control of the reflection and transmission of infrared light or heat dissipation,” said Gorodetsky. “The mechanism is analogous to chromatophore expansion and contraction in a squid’s skin, which alters the reflection and transmission of visible light.”

Chromatophore size changes help squids communicate and camouflage their bodies to evade predators and hide from prey. Gorodetsky said by mimicking this approach, his team has enabled “tunable thermoregulation” in their material, which can lead to improved energy efficiency and protect sensitive fingers from hot surfaces.

Friday Squid Blogging: Do Squid Have Emotions?

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2022/04/friday-squid-blogging-do-squid-have-emotions.html

Scientists are now debating whether octopuses, squid, and crabs have emotions. Short answer: we don’t know, but can’t rule it out.

There may be a point when humans can no longer assume that crayfish, shrimp, and other invertebrates don’t feel pain and other emotions.

“If they can no longer be considered immune to felt pain, invertebrate experiences will need to become part of our species’ moral landscape,” she says. “But pain is just one morally relevant emotion. Invertebrates such as octopuses may experience other emotions such as curiosity in exploration, affection for individuals, or excitement in anticipation of a future reward.”

Friday Squid Blogging: Squid Migration and Climate Change

New research on the changing migration of the Doryteuthis opalescens as a result of climate change.

News article:

Stanford researchers have solved a mystery about why a species of squid native to California has been found thriving in the Gulf of Alaska about 1,800 miles north of its expected range: climate change.

Friday Squid Blogging: Unexpectedly Low Squid Population in the Arctic

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2022/03/friday-squid-blogging-unexpectedly-low-squid-population-in-the-arctic.html

Research:

Abstract: The retreating ice cover of the Central Arctic Ocean (CAO) fuels speculations on future fisheries. However, very little is known about the existence of harvestable fish stocks in this 3.3 million­–square kilometer ecosystem around the North Pole. Crossing the Eurasian Basin, we documented an uninterrupted 3170-kilometer-long deep scattering layer (DSL) with zooplankton and small fish in the Atlantic water layer at 100- to 500-meter depth. Diel vertical migration of this central Arctic DSL was lacking most of the year when daily light variation was absent. Unexpectedly, the DSL also contained low abundances of Atlantic cod, along with lanternfish, armhook squid, and Arctic endemic ice cod. The Atlantic cod originated from Norwegian spawning grounds and had lived in Arctic water temperature for up to 6 years. The potential fish abundance was far below commercially sustainable levels and is expected to remain so because of the low productivity of the CAO.
